Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Hello and welcome to just answer Dodge. This sounds like 1 of 2 things: 1, a failed ASD relay because of high resistance across the relay's contacts, or 2 a failed PCM (ecm). The ASD relay supplies voltage to the ignition coil and the injectors, and then the PCM pulses the ground circuits of the injectors and coil. Try this: swap out the ASD relay with another like relay (horn, ac, etc.) and then see if that helps. If you still have an issue, check all fuses for poor connections. If she still won't start, suspect a failed PCM.
Hope this information helps, and let me know if you need more assistance with this.
Hmmm, The no compression thing may be caused by the cylinders being washed down with fuel, like the injectors staying energized. Pull the spark plugs and see if they are wet with fuel. Do this right after cranking the engine and let me know what you find.
Hi Chris, You are welcome, and let me know how it goes when you get the PCM back. I am assuming the engine ran after the timing belt and water pump job, and then quit 3 days later. If that is the case, and the marks still line up, then engine mechanical is probably ok. Again, let me know how it goes,
Sounds good, I will look for your reply down the road,
Hi Simon, the cam and crank sensors should show "sync" while cranking if they are actually in sync. You say that they said compression was very low, did they give you the actual compression test numbers? Also, I have never seen a sync problem caused by a bad PCM (yet). I see that you said " so I must of put it on wrong bent the valves then put it right..." Do you think you got the belt on wrong at first, cranked it and then re timed the belt? If so, then you may have bent the valves .
Maybe you should pull the head yourself and check to see if the dealer is correct?
Sounds good Simon, Ley me know, and thank you for the accept!
Hi Simon, Sounds to me like you were correct in setting the valve timing if there is no visual evidence of valves contacting the pistons. As far as the cost of a PCM, that sounds very high to me. A re manufactured PCM should be no more than $300.00, and no more than an hour of labor. You may want to call another dealer and ask them what they charge to replace a PCM on this vehicle ( pretend you are just a regular customer asking around). If you need me to, I can check on the price of a PCM from my dealer. Let me know and I will be happy to do that for you.
