Hello Fellow Feline Friends!!




To start from the beginning here we go. I gave someone a jump, went home and several hours later my car would not start. After being at the shop for a month or more they came to the conclusion that my ECM was fried. ECM was sent out and confirmed fried. I found a ECM, matched the numbers up(Thanks to You Guys!) and took the car to the Dealership to be programmed. The dealer said the car was programmed with no issues but still would not start. That's when they discovered the fuel reservoir was clogged and allowed water into my fuel tank. They told me I needed a new fuel pump installed. Installed the new pump and still not starting. Any suggestions friends?

 

Have they checked that the coils are actually firing? There is spark?

Sufficient fuel pressure? Injectors are spraying?

Basic stuff but that's what you need to be looking at now...

 

Should these things be checked again? They were checked before the ECM and fuel pump replacement. How can I check for Spark? I know the shop did compression, I just don't know how

 

You can put a clip-on timing light on the wires that run to the coils, it'll flash when the coil fires.

If the car was in a workshop trying to get the engine started i'd expect them to have checked these sort of things?

 

I'm assuming the watery gas was drained and replaced with fresh fuel during the fuel pump replacement?

 

I assume it's turning over but just not firing. At the most basic level an engine only needs three things to run:

1. spark
2. fuel (gas/air misture)
3. compression

but in your case I would check the spark plugs first. Take them out and visually inspect them. Maybe there's water in the cylinders

 

Have they checked to see if the inertia switch is set. Maybe bumped bumpers when you jumped the other car. Does your other key also not start the car: keys lose their codes, especially with a new ECM.

Fuel, spark, compression! But lots of things effect those three on modern cars.

It would be useful to know what year and model: bore wash, washes oil off the cylinders and you get no compression.

 

I would try a hard reset first.

 

I would check the ground for the ECM, be sure they relayed it.

As much as we would like to be good samaritans, any car made 97 and later should not be used to jump other cars. Buy a jump box, or as I highly recommended in another thread (I have one and its great), get one of these or one like it....

 

I don't see a problem jumping if you disconnect the battery first. Of course, you end up with a reset then, but that shouldn't be a major deterrent.

 

Thanks a lot for all of the suggestions, I will be trying everything mentioned here. I really appreciate you guys, I will be updating my findings A.S.A.P.

 

Yes true, but with the XP10 (or the like), you don't have to try and maneuver the cars so the cables reach. Check their video out on YouTube, that's what convinced me to buy one.
