Not going to get much help here on a 5th Gen (2010-2015) forum. Let's move this to “General 67-02 F-Body Tech”. Could try the “V6 Tech” forum, but not much activity there.

Need more info:

- what happens when you turn the key to “run”? Do the dash lights come on briefly? Do you hear the fuel pump run for two seconds?

- what happens when you turn the key to “start” - does it engage the starter and crank the engine, or nothing at all?

- if it cranks the engine, any sign it’s trying to start - pops or a sputters from a few cylinders firing?

- have you scanned it for codes, or have you checked the fuel pressure?

When you say “alarm”, what are you referring to - the PASS-Key (VATS) security system, the optional factory alarm system, or an aftermarket alarm system?

You indicate the “SECURITY” light doesn’t flash. When you turn the key to “run” does the “SECURITY” light come on during the bulb check, then go off after a few seconds? When you try to start the engine, does the light come on and stay on (as opposed to “flashing”? That would indicate a mismatch on the key resistor. Flashing indicates the circuit that reads the key resistance is faulty. Since the starter engages and cranks the engine, the resistance check was OK.

Then there's the fuel enable signal from the body control module (BCM) to the PCM. Is that what you mean by “an alarm interface to bypass alarm”?

Questions you didn’t answer - Have you checked the fuel pressure? There are a lot of low quality and even counterfeit fuel pumps on the market. I've seen cases where the flex line in the fuel tank has cracked during pump replacement, and even cases of the flex line connection not being tight. Then there's the possibility of a plugged fuel filter.

And... have you checked the PCM for codes?

What alarm system?. It would be easier to help you if you answered ALL the questions. Not every 96 has a factory alarm system.

You can check the fuel pressure with a $25 fuel pressure test gauge. Or, you may be able to borrow one from an auto parts store with a refundable deposit.

OK - thanks for sharing. I asked you in post #4 what you were calling the “alarm”. You never directly answered the question. You failed to answer several questions.

Since you are obviously not satisfied with my feeble attempt to help you, I'll stop bothering you. Maybe someone else will want to help you.

Might want to lose the attitude.
