Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Hi my name is Greg and I will try and help you. tell me what you've done so far and what your truck is doing and what happened before it failed.
Also which engine we are working with
have you checked for codes?
possible crank sensor?
possible fouled plugs?
Have you tried spraying anything into the intake to see if it fires up?
Well if you are measuring 65 psi at the test port on the fuel rail then fuel pressure likely isnt the issue.
lets go back to try spraying carb type cleaner or such into the intake and see if it starts. I am trying to help figure out if we have a injector type issue or something else it takes 60 psi to start this engine bu tif the injectors are firing for some reason then we know where to start. also If you have a test light you can disconnect an injector put the test light in place of the injector and crank the engine, it should flash. as your turning over the engine.
like I pointed out too this could be a crank sensor issue.
have you removed the dist cap? you could have weak spark or incorrect spark due to it jumping those dist caps get very corroded at times and cause strange drivability issues.
and no current codes?
tell us if your timing jumped, low or no comp and it wont start.
tell me what originally happened with the vehicle?
what about when you hook up the pressure gauge and shut the engine off does it hold fuel pressure for awhile?
and you ve replaced all the injectors?
Have you tried to see if It is a sec system issue?
does the security lamp flash?
any bcm codes?
Did you find the point of resolution for this issue?
