Have you checked the impuse of the injectors? If you got fuel pressure, I'ld look there if it runs with adding gas through the intake.

99 grand am 3400 gt doesn't start. It ran fine , but now it won't start. It has spark and fuel . all fuses are good . Cranks over but doesn't start. It only stars if I put gas in the throttle. ????...

Check your ignition module.
My thought is, you have no fuel injector pulse. The voltage for fuel injector probably goes hot with the key on, the computer controls the ground circuit. If your missing rpm signal, no fuel injector pulse.
Another thought is antitheft/security system, where applicable.

My 2004lmpala wont start 3400 engine ?

If it cranks good but won't start, have a helper crank it while you visually check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure. Also check for fuel injector pulse.

What lights, are you talking about dash lights? If so, some of those items may not go hot until you turn on the key. Then I would check ignition switch and wiring. I haven't looked at your wiring diagrams. I would think the horn circuit would be hot all the time.

Cranks, will not start

Sounds like a bad fuel pump. Check the schrader valve for fuel, or check fuel pressure. Listen and hear if the pump is turning on when priming the ignition.

you might not be getting a injector pulse signal at # 3 cylinder ? easy way to check this is with a noid light, it plugs in to the end of the connector and as crank the engine the light should flash. if it does not flash check wire harness for a open circuit from injector to computer ( e.c.m.) if thats alright possibly e.c.m. bad . if you cant find noid light you can use a digital volt meter. good luck

1999 Pontiac Grand Am with "lower intake leak"...What does this mean specifically? Would this mean the intake for the radiator, gasket, or valve?

Usually intake has to do with the induction system, as in intake manifold , The intake manifold can have several types of leaks, the intake can have a vacuum leak, oil leak, coolant leak or a combination of any of the before mentioned....hope this helps,
