I have a Pontiac grand am 91. I was driving down the road and it just cut off. All the fuses are good and the fuel pump is good and the fuel filter, It has spark to the plugs. It cranks over but will not start up. What else can I check?

Use a noid lite, check for injector pulse, engine cranking. Any applicable mil codes? You can check those, yourself.

Use a gage and check fuel pressure.

If the fuel setup isn't factory, I don't know what to tell you? What is the fuel pressure spec?

It's factory setup nothing new on it. No fuel injection it has a carburetor. The pressure was around like 41psi or so.

You should have fuel injection. My info shows this, below, for 2.3L engine.

How about checking for trouble codes? Use a jumper wire between A & B terminals of data link connector. Turn key just till dash lites come on, no further, mil starts flashing, you count the flashes to get the codes. Your looking for two digit codes.
