Sounds like it could be a crank sensor or a bad coil pack

    Could it have n e thing to do with my fuel pressure regulator?

    Regulator usually they won't start up or dies after a short idle time. You can test the fuel pressure on with a pressure guage and key on, then turn key off and observe the leak down time, or loss of pressure over a five minute span. Any more than about a 5-7 PSI drop and it could indicate a bad regulator

    Iv'e also had a plugged catalytic converter do than too after a short drive the exhaust overheats and causes the engine to die. Should be some water dripping from tailpipe when engine is running, or converter could be shot.

This could be a number of things but i think that your problem sounds like a vacuum leak or an EGR problem. Try listening for leaks and try un-plugging the EGR solenoid valve one time.

SOURCE: 89 suburban. No spray from injectors after replacing ESC

The fuel pump should be in the 20s. Also it could be losing presure slowly. Leave the fuel pump pressure gage on for at least 2 to 3 hours to see if it is losing pressure - It's a start

SOURCE: have a 96 chevy cavalier. replaced IAC,fuel pump

If your oil pressure gets to low it can turn off the fuel pump. This may also have saved your engine. The ECM turns on the fuel thru the fuel pump relay for about 5 seconds. When engine is running oil pressure sender supplies the voltage to the pump. When engine shuts off check oil pressure and voltage to fuel pump.

Cranks but wont start with no spark


Check your fuel pump. It may have died. One way to check is to see if you smell gas at the tail pipe after trying to start it. If you don't, that is a good indicator that the fuel pump ma have died or your fuel filter is clogged.

MY GIRLFRIENDS 89 CHEVY CELEBRITY DIES WHEN TURNING


Try replacing the fuel pump relay, or you may have a PCM (computer) and prom failing. Underneath your hood, behind the passenger side headlight, behind the core support, is a bank of 2-8 relays. One of those relays is the relay needed for your fuel pump. There will also be a fuel pump relay fuse located there.
Inspect that area for any corrosion or loose wire (bad ground) Good luck and here is a link for you to retrieve your DTC codes and that may help you resolve the car's issue.
