SOURCE: I HAVE A 1996 INTREPID.

Maybe check the flex plate. I had a 94 concorde with a similar problem. Scanner said it was the cam and crank sensors. The flex plate can get a crack around the bolt pattern which allows it to shimmy when running. throwing off the cam and crank somehow as the mechanic tried to explain to me.

SOURCE: 1997 dodge ram won't start. My fuel pump does not

First check any ignition/fuel related fuses. Check to make sure you have 12 volts coming into the pump and coil. If nothing to the fuel pump replace the fuel pump relay - if you do have power to the fuel pump then replace the pump. If nothing is coming to the coil it is either an ignition relay or a wiring issue. If you have 12 volts to the coil but no spark then replace the coil.
Also the fuel pump/relay would not kill the coil.

The red immobilizer light is staying on,the engine cranks but wont start..


You then have a ant-theft system problem an need to have the vehicle checked for DTC'S - diagnostic trouble codes . The ASD - relay supplies power to the ignition coils an too the fuel injectors .The ASD- auto shut down relay is energized by the engine computer - PCM . With the red anti-theft light on the PCM will not turn on the ASD relay cause a no start condition . You can check fuse an relays all you want ,not going to do any good . You need to see what the ant-theft systems problem is .

I have a 2002 dodge intrepid cranks but no spark.changed cam shaft sensor and crank sensor., all new plugs but still no spark....please help ..thanks


Hi Leroy, Im glad to help!

Here's a couple things you can try. First, swap the ASD Relay with one of the same type relays in the relay box. If it still doesn't start check every fuse. If it still doesn't start check power and ground at the "COIL PACK" If power and ground are good Replace the Coils Pack. If there is no power and ground at the coil pack then make certain you are getting power from the ignition switch to the ASD Relay. Hope this helps and have an awesome day Leroy.

My dodge neon 2002 has no power to coil pack


Check to see if there is power to the injectors. They are fed from the same fuse and relay. If there is no fuel pressure than the fuse would be the fist suspect sin the ASD and fuel pump relay are fed off the same fuse. The fuse is fuse 21 in the power distribution center.

If the fuse is good try swapping the ASD relay with another relay in the fuse block that is the same. If you know have spark than replace the ASD relay.

Getting gas no spark. coil and power into the coil good. 1990 dodge dakota with a 3.9.


The coil, injectors, and fuel pump get power from the ASD relay. If you have power to the coil but no spark from the coil, have you checked the pickup in the distributor ?
The pickup sends a signal to the engine computer and the computer fires the coil.

2005 dodge neon key turns nothing happens. I hear fuel pump buzz but wont turn over. can jumpthe starter to turn over but still wont start. Checked fuses,relays, what now?


The ASD relay powers the injectors and the coil.
Have you checked it to see if you have power in and out ?
The engine computer grounds the starter relay, injectors and coil, could be something going on with it.

91 buick skylark 3.3 v6 has spark but no power to injectors


your injectors get their 12v from the asd relay and the computer controls their - side. the asd relay also powers the coil, so if you have spark but no juice to the injectors then you are looking for a broken wire to the injector rail. all of the injectors get their juice from that one source.

1995 Ram 1500. Just died? No votage to coil, no spark?


The power supplied to the fuel pump, ignition coil, fuel injectors and parts of the power module is controlled by the logic module through the Automatic Shutdown Relay (ASD):
The ASD relay is closed (allowing power to flow through it) when the ignition is first turned on. If the signal from the ignition reference is lost while the engine is running, the logic module cuts power to the ASD, which in turn removes power from the fuel pump,ignition coil, injectors and those parts of the power module.  This causes the engine to shut down.

Failure of the automatic shutdown relay is often shown as inexplicable stalling or refusal to start. The ASD can be triggered by a broken wire or short in another place, e.g. the fuel pump.  Hope this helps, and did you try to retrieve any DTC codes?? Be glad to help friend.

Engine won't start


Sounds like an AUTOMATIC SHUTDOWN (ASD) RELAY problem. Fairly common on the Caravan.
Heres a brief overview of the ASD.
The Powertrain Control Module (PCM) operates the Auto Shutdown (ASD) relay by switching the ground path on and off.
The ASD relay supplies battery voltage to the fuel injectors, electronic ignition coil and the heating elements in the oxygen sensors.
The PCM controls the relay by switching the ground path for the solenoid side of the relay on and off. The PCM turns the ground path off when the ignition switch is in the Off position unless the 02 Heater Monitor test is being run. Refer to On-Board Diagnostics. When the ignition switch is in the On or Crank position, the PCM monitors the crankshaft position sensor and camshaft position sensor signals to determine engine speed and ignition timing (coil dwell). If the PCM does not receive the crankshaft position sensor and camshaft position sensor signals when the ignition switch is in the Run position, it will de-energize the ASD relay.
The ASD relay is located in the Power Distribution Center (PDC). The PDC is located on the driver's side inner fender well Power Distribution Center . A label on the underside of the PDC cover identifies the relays and fuses in the PDC
Check for good ground.
Good luck...i hope this helps, please rate me a fixya.
