Most likely the electric fuel pump in the tank is bad. You will here it hum while cranking. The failure is that the pump is not pumping enough fuel to keep the engine running. There are plastic tubes on the pump that deteriorate and get pin holes in them and leak fuel and lowering the volumn of fuel.

Also remove the vac. line to the fuel pressure regulator on the fuel injector rail. The fuel pressure regulator has a history of leaking fuel into the vac line and flooding out the engine. (Wear saftey glasses when removing lines)

Engine stalls on Isuzu I-370 truck after warm up


The Cam sensor usually senses the position of the timing belt or timing chain gear and tells the computer when #1 cylinder is at top dead center. In other words, when #1 cylinder comes up. Crank sensor tells the computer when to fire the spark plugs in the rest of the cylinders. In other words, as the crank shaft goes around it tells the computer when each piston comes up so it can fire it's spark plug


so replace the crankshaft sensor

Have you checked Google I found this hopefully it's not your timing or it may be flooded but doubtful have you tried spraying starting fluid into the intake while cranking it

1995 pontiac bonneville stalls


I just went through lots of troubleshooting and expense on my 1996. Whenever I would lift my foot off the accelerator and was below about 30 mph, the rpm's would starts jumping around and sometimes it would stall. If I gave it a little gas (accelerator), I could sometimes keep it running. It also backfired once in a while. Starts right back up. Also, if I let it idle while in part, it would die after 1-2 minutes.

I ended up finding a hole in the fuel regulator. About a ~$70 part if you get an AC Delco, but very simple to change.
