Check the ASD relay , auto shut down relay in the under hood fuse / relay box . The ASD relay supplies B+ voltage to the injectors an ignition coils plus other thing's ! This may be you device voltage code problem as well as the other codes

    Checked all fuses OK. Installed new crank senor. Still no spark. .or injector pulse. Really stumped. .tracked all wiring checking for breaks. .nothing.

    Also have power to one side on each coil pack

  • Jeff Armer May 09, 2016

    If you have power on one side of the coil ,then your missing the control side . The PCM - engine computer controls the coils by supplying a ground . Probably the same for injectors .If you do have B+ voltage on the dark green with a lite green stripe that's good , so is the ASD relay . But bad news the PCM is not grounding or controlling the coils or injectors . Could be a bad PCM or no power or grounds for the PCM .Go here to look at a wiring diagramhttp://www.bbbind.com/free_tsb.html free wiring diagrams . Also go on youtube an check out videos on trouble shooting ignition systems .https://youtu.be/01kxE1gMgio?list=PLAFYV...

    Well figured out my problem. The garage that installed the engine put a 2008 2.7 magmiun engine in a 2001 dodge intrepid and used the intrepid fly wheel.which had different timing marks. Their for the cam sensor and crank senor are not timed

  • Jeff Armer May 11, 2016

    There are a couple of videos on youtube ,about Chrysler , dodge ,jeep engine swaps cam sensor trigger wheel problems . different then the original .https://youtu.be/b6I-eXb34yk

Injectors not firing on GM 3.8 engine on buick lesabre 2004


Are you missing anything else? Engine cranking, do you have spark at the plugs? Also, use a gage and check proper fuel pressure, engine cranking. Any applicable trouble codes? If your missing spark--fuel pressure and fuel injector pulse, I'd have to check for rpm signal, usually, comes from crank sensor.
Key on, did you check for voltage on pink wire at fuel injector, use a test light to check for voltage. The computer grounds the fuel injector if rpm signal is present.
I don't know what testing you have done?

1997 pontiac sunfire crank no start condition. Have spark, no codes, have injector pulse, good fuel pressure. But it seems that the injectors are not letting fuel into the cylinder.


Did you check the actual voltage reading to fuel injectors? I wondered about a voltage drop? Your fuel pump relay supplies voltage to both fuel pump and fuel injectors.
In the diagram, the gray wire is voltage and the other color is ground controlled by computer. Did you check fuel injectors, individually?I'd want to use a gage and check proper fuel pressure. Fuel--spark--compression--timing. There are other ways to get fuel in the engine besides fuel injectors, Just to see if engine will hit? There are safety issues, safety is your responsibility.

N0 p0wer to fuel pump


I have to ask. How long since a tune-up? Are there any applicable trouble codes?
With engine cranking, if no spark at the spark plugs and no fuel injector pulse along with no fuel pump action, have to check rpm signal.
If you have spark and fuel injector pulse but, no fuel pump action, then we check the fuel pump circuit. Did you check applicable fuse, not only check the fuse, check the fuse circuit for voltage. At the fuel pump connector, gray wire is voltage for fuel pump motor and black wire is ground.

NO INJECTOR PULSE SPARK IS GOOD HAVE BATTEY VOLTAGE AT INJECTORS NO GROUND PULSE WHY


Open circuit to PCM - the engine computer grounds the other side of the injector there by turning it on an off very rapidly . This is call PWM - pulse width modulation . There is a transistor in the computer that does this . Or the PCM is bad !

Has spark no injector pulse has power to the injectors


No pulse means the injector ground side is absent, since you have power to the injectors. The ground wire goes into the engine computer to be internally grounded for the pulse. You can test the injector ground side with a test light, as a verification of it not having pulse. If it really has no pulse, but it has correct voltage to the injector solenoid, then you have a bad injector, or a bad ground wire to the pcm, or a bad pcm.

Use a test light with a ground clip and a needle-type probe. Unplug the injector connector and note which is the power wire terminal and which is the ground wire terminal. Clip the test light lead to the POSITIVE battery post, and put the probe into the injector's ground wire terminal. Now have someone crank the engine over and watch for a blinking light on the tester. If you have a blinking light, the injector ground side is working right, so check if voltage to the injector is correct, or if you have a bad injector. If you have no blinking light, then no pulse is correct. You will need to check the ground wire to the computer before assuming a bad computer. I think they are called quad drivers inside the computer that control the injector grounds.

Best way to check that ground wire is, first, take off the negative battery cable, then pull off the computer connectors, then use an ohmmeter to check resistance of wire from injector terminal to the pin on the computer's connector. Low resistance, low ohms, means the wire is good. ...But first I guess you will have to find the pin-out diagram for the computer, where and on which connector that ground wire goes in at. There's around a hundred or more wires going in, so color coding, tracing by the color of the wire would be a royal pain. Good luck, Scott.

No injector pulse


1991 this make you OBD1 . You can access a code by jumping 2 terminals together.The injector pulse is from the PCM . If you have no pulse you need to troubleshoot for spark first . If you dont have spark do spark first then injector pulse comes on. If no injector pulse check fuse in engine junction box.Use a volt meter check grounds at PCM. If all else checks out good replace PCM. You may also want to check the TPS. If this sensor short out in the WOT position you also wont get injector pulse.SO disconnect the TPS. and recheck for injector pulse

1996 buick park ave, wont start, has spark but no voltage at injectors...


Spark indicates crank sensor, ignition coils and modules-ok
no voltage at injectors; should be 12v in each of the injector wires (not the black one) with key on engine off. Voltage provided to injectors comes from injector driver circuit inside PCM, and pulses ground signals to open and close injectors.

Fuel injector won't allow gas to flow into engine, have spark, have fuel psi. All fuses ok. OBD connection won't connect to reader can't get codes.


    Test fuel injector pulse and supply voltage output (test is used for most cars). This test will tell you if the computer system has operating voltage and injector trigger signal. Remove an electrical connector from a fuel injector (it doesn't matter which injector) probe both sides of the connector with a grounded test light
    (there are only two terminals). Have a helper turn the key to the "on" position without cranking the engine and observe the test light. The test light should illuminate one side of the connector only. Next, switch the test light lead to the positive side of the battery to test the system ground injector trigger, probe the side of the connector that did not light up, have a helper crank the engine over and observe the test light, it should blink on and off. If this test checks ok continue to next step. (Note: if no injector pulse is present try disconnecting the remainder of injectors and re-test, if a fuel injector is shorted it can shut down the injector driver causing no injector pulse. If injector pulse returns plug injectors electrical connectors in one at a time until the pulse fails and replace that injector)

    If this test revealed that there was no pulse but system has power the ECM is not generating a fuel injector trigger. If there is no trigger to the fuel injector it will not allow fuel to enter into the engine. Some of the most popular reasons that can cause this condition include a shorted crankshaft angle sensor, shorted camshaft position sensor or shorted ECM/PCM. (When a system trouble code scan is performed it does not always catch a crankshaft angle sensor, camshaft position sensor failure). Tip: try disconnecting all non-essential sensors, example: oxygen sensor, coolant sensor, throttle position sensor, air intake temperature sensor, mass air flow or map sensor and EGR valve pressure differential sensor. Crank the engine over, if the injector pulse returns, one of the sensors is shorted causing the system to not operate. Plug the sensors in one at a time until the injector pulse fails then replace that sensor and reassemble.

Engine will Turnover but it will not fire up


To check injector pulse, you need 2 people. One is to crank the engine. The other is to watch the voltmeter connecting to the plug delivering the electrical signal to an injector. If during a period of cranking, there is no voltage displayed that means there is no injector pulse. Here is an image of connector port going into the injector to open its valve as needed.d63fc52.jpg

1985 corvette no pulse to injectors


Very important that if you are not savvy of working on your Vette ...you would be better off - taking your car to a dealership for repairs on your trouble codes. However if you feel that you want to, First locate your car's alcl this component is located just below the instrument panel and to the left of the center console. Remove the plastic cover the first two slots to your right are the A & B slots.
The A slot is the diagnostic slot and the B slot is the ground slot. Insert the computer key into these slots if you do not have a computer key, a paper clip or wire jumper clip will do, (with the engine off) this is very important...now only put the ignition key to on ( not start !!!) the check engine light will display a code 12 which is one flash followed by two flashes. This code will be flashed three times ..followed by the trouble code stored in your car's computer.

What ever the code is it will be flashed three times. Have a paper and pencil ready and write down the code.

Code #12: Normal No Codes. 
Code #13: Open Oxygen Sensor Circuit. 
Code #14: Coolant Sensor Circuit Low.
Code #15: Coolant Sensor Circuit High. 
Code #21: Throttle Position Sensor High. 
Code #22: Throttle Position Sensor Low. 
Code #23: Manifold Air Temperature Circuit High.
Code #24: Vehicle Speed Sensor. 
Code #25: Manifold Air Temperature Circuit Low. 
Code #32: EGR System Failure. 
Code #33: Mass Air Flow Sensor High.
Code #34: Mass Air Flow Sensor Low. 
Code #36: Mas Air Flow Sensor Burn-Off Function Fault. 
Code #41: Cylinder Select Error. 
Code #42: Electronic Spark Timing.
Code #43: Electronic Spark Control. 
Code #44: Lean Exhaust indication. 
Code #45: Rich Exhaust Indication. 
Code #46: Vehicle Anti Theft Fault. 
Code #51: Faulty Mem-Cal. 
Code #52: Fuel Calpak Missing.
Code #52(1990-91 Corvette Only): Engine Oil Temperature Sensor Low. 
Code #53: System Over Voltage. 
Code #54: Fuel Pump Circuit Low Voltage. 
Code #55: Defective ECM. 
Code #62: Engine Oil Temperature Sensor Circuit High.

Please remember that if you have the computer key installed in the alcl and you start the engine (you will ruin the engine's computer) only put the ignition to on (not to start).

If you should get a check engine soon display.. you can use the above procedure and codes to buy the right part or at the very least to keep from getting taken for a ride and be made to pay hight prices for some inexpensive module that you could have installed yourself.

If your engine displays a trouble code ... your engine will go into limp mode ..it will still run but very poorly. You might be able to reset the computer if it will not start (just to get home) by disconnecting both battery cables and re-installing them ...this is not recommended ..but if you are stranded it might help unitl you get your car home or to a repair shop..good luck.

Good luck and hope this helps.
