Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose).
With the throttle body open while cranking will it start using starting fluid?
What compression readings were you getting and did you do a leak down test?
I have to agree on it either spraying fuel at the wrong time or sparking at the wrong time. Monitor the cam and crank sensors for an inconsistent reading. If they are fine then I would replace the computer.
Now that I have posted a partial or complete answer, you will see you can rate me. The deposit you have already paid is not transferred to me until you rate me. I would like to receive nothing less than 5 star excellent ratings. So if we are not there yet, please reply and let me help more. If you're not pleased, let me know because rating bad does not result in a refund, there are better options. Rating now will not close this post nor prevent replying. Thanks Chris
The computer which controls the injectors the plugs is what I would go after next. Everything else is doing its part.
I still feel like the computer is to blame in this case not firing the plugs or injectors at the correct time based on all the other tests you have done assuming that info is accurate.
Hello Chris here again,
