Sounds like a fuel pressure problem. Sounds like you are going to need to check fuel pressure. Or at least listen for the pump in the tank to hum when you turn the key on, or when cranking.
If do not have access to a gauge, you can remove the air intake from the engine and spray carb cleaner, brake cleaner or ether in the engine while cranking. It would make it run, but not well, if everything else is fine- EXCEPT fuel pressure. This would indicate a bad fuel pump.

You are going to have to find out if you have spark or not as well. Just because it wont start does not mean it is a fuel pressure problem.

1995 Monte Carlo Z34 just quits running

Unread post by tatman20079 » Fri Oct 25, 2013 3:27 am

My 1995 Monte Carlo starts and runs fine for a while and then all of a sudden just quits running, I check to see if it is getting fire and Nothing... an hour later I can go out and check it again to find that the fire is just as strong as ever... What is going on???

so you check and there is no spark while cranking? Check you crank signal. Crank sensor, ignition module, ECM, and even fuel injectors can shut down an engine just like someone turned off the key while you're driving. Oh yeah, the ignition switch too. You have to check to see what you have and what you are missing when it cranks over and doesn't start again.

Here is one example:

continues to run normally or does it cough and run badly?

how long does it run? How do you turn it off if it keeps running? Does it turn off if you open the door?

has anything been done with the radiator fan circuit? (Any wires spliced in to make the fan run?)
