1998 firebird formula turns over but want start

Is the security light on?

the security light stayed on blink that night.but we did not do it with the remote.we had 2 quit using the remot because of the stripped gear in hl motor.now when i go to start it the security light blinks for 5 seconds and goes off/normal/but the car turns over but want crank

You need to check for spark, if it has spark then check fuel pressure, if fuel pressure is good then check for injector pulse.

ok iwill try that this weekend. can do spark check and can borrow guage 4 fuel press. not sure about injector pulse. so u dont think its security system? also i can hear fuel pump turn on

If the security system is having an issue then it will turn the light on and leave it on. Just because the pump runs doesn't mean it has good pressure. To check injector pulse you can rent a noid light set from auto zone which you unplug the injestor and plug the noid light into the harness, crank the engine and watch for it to blink. If it blinks its getting pulse.

It might be the vats system. Check LS1tech for the fix

I have a trans am 1999 it starts up then cut off it keep resetting itself the security light comes on then go off
