check ground wire

You might try to check the ignition module or the fuel pump relay

a faulty oil pressure switch which incorporates the fuel pumps prime
Once the oil pressure is acheived the fuel pump relay takes over running the fuel pump

Check the ground. If power is present might have a bad ground

adjust switch or replaced it and disconnect post battery and wait few minute until computer clear it self and for a/c check your blow fan and check your freon.

new engines always receive a tune up with new parts. The brochure that comes with these engines highly recommends that for the warranty to be intact. Do that first if not done yet

change the coil

15mm

bad ground, or needs a relay to handle power,

Sounds to be in your pig tail. Might take some electronic spry cleaner , WD/40 work sometimes. Should just be in the connection. good luck

yes most chevy's are very compatible...

Hi, hope I can help.
Have you checked your battery.
Make sure you have 12volt on your battery first.
Next in what condition are the battery post and connectors.
Make sure they are clean inside and out.
So remove your connections and use a wire brush and clean them post and wire side.
Next you will want to put a muilti meter and check if that 12v is making it to the starter.
Check the wire coming from your batt to your starter ,on the starter side place your meter on that post and check for your 12v.
If you have 12v there check the other large post on the starter , There are only two of them and you just checked the first one.
This one can be identified by the thick wire brade that goes from the post to the starter it self.
Now have some one turn the key as if they are starting it. (be clear of all moving part).
If you get 12v there then your starter has fail and must be replaces.
If you don't get 12v there when the key is turn we must continue to check.
Next you would have to check the small wire going to the starter.
With the key off you should not have any volts.
Now turn the key. With the key to the start position you should get 12v
If you have 12v. there and 0volts at the post with the braided wire you solenoid has failed.
You have two options to make from there.
If you handy you can just change the solenoid or you can just change the starter.
Hope this helps

P0340 OBD-II Trouble Code - Camshaft Position Sensor Circuit Malfunction

This indicates that a problem was detected in the camshaft position sensor circuit. Since it says circuit, that means the problem could lie in any part of the circuit - the sensor itself, the wiring, or the PCM. Don't just replace the CPS (camshaft position sensor) and think that will definitely fix it.

Symptoms can include:
* Hard starting or no start
* Rough running / misfiring
* Loss of engine power

Causes: A code P0340 could mean one or more of the following has happened:
* a wire or connector in the circuit could be grounded/shorted/broken
* the camshaft position sensor may have failed
* the PCM may have failed
* there exists an open circuit
* the crankshaft position sensor may have failed

Possible Solutions: With a P0340 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:
* Visually inspect all the wiring and connectors in the circuit
* Check for continuity in the circuit wiring
* Check the operation (voltage) of the camshaft position sensor
* Replace the camshaft position sensor as required
* Check the crankshaft position circuit as well
* Replace circuit wiring and/or connectors as required
* Diagnose/replace the PCM as required



P0133 OBD-II Trouble Code - Oxygen Sensor Circuit Slow Response (Bank1, Sensor1)

This involves the front oxygen sensor on Bank 1. This code indicates the engine air fuel ratio is not being adjusted by the oxygen sensor signal or the ECM as expected to do so, or not adjusted as often as expected to do so once the engine is warmed or under normal engine use.

Symptoms: You will likely not notice any drivability problems, although there may be symptoms.

Causes: A code P0133 may mean that one or more of the following has happened:
* The oxygen sensor is faulty
* The wiring to the sensor is broken / frayed
* There is an exhaust leak

Possible Solutions: The simplest thing to do is to reset the code and see if it comes back.
If the code comes back, the problem is more than likely the front Bank 1 oxygen sensor. You will likely wind up replacing it but you should also consider these possible solutions:
* Check and fix any exhaust leaks
* Check for wiring problems (shorted, frayed wires)
* Check the frequency and amplitude of the oxygen sensor (advanced)
* Check for a deteriorating / contaminated oxygen sensor, replace if necessary
* Check for inlet air leaks
* Check the MAF sensor for proper operation


Hope this helps (remember to rate this answer).

front seal or pan gasket look and see where it come from 9106545823 if you need help

Your talking about an astro van right? If so the timing is not adjustable. It is set by the computer, using various sensors, like the crankshaft position sensor, the throttle position sensor and others.

did you replace the trans harnes and solenoids? It is a very common failure
good luck

hi ,this is a problem with your fan resistor which is located near your interior fan under the dash in most vehicles ,they are normally fairly easy to access as they are a seperate replacable item ,its the size of a half a cigarette packet and are usually held in place by 2 screws with a 4 or 5 wire plug going to it ,when removed it will either have a white chalky resistor on it or a newer type alloy heat sink on it. you can replace it new from your chevy dealer or source a second hand one from a chevy wrecker ,have the part number on it ready for them when you phone up for a quote ,i hope this info was helpful as its all there is to know about this problem (note : the only other cause can be your fan switch when on high but this is very unlikely)
THANK YOU for using FixYa

scale 1 to 10 about a 6 but make sure its not the wheel bearins cause they can houl like the axles are bad and mush easyer to change

standing in front of the vehicle its the one at 4 to 5 o clock pisition the fireing order is 165432 . And if you are doing timeing chain work # 4 clinder is the one that has to be at TDC to align the timeing chain for correct timeing
