Fuel pump relay comes to mind
There are a few things which would open the relay such as the inertia switch, ignition switch, and the clutch safety switch, but usually they wouldn't allow you to actually start the car
I'd hook up a fuel pressure gauge to it?
You should have a schrader valve on the fuel line to make it real easy
Hook it up, turn the key to on but not start-check the pressure, start and run-check the pressure, and when it dies check the pressure

When it's in no-start, check for spark at the plugs

Also pull the codes there may be something in there that's helpful

Can you restart it after it dies?
Do you have to turn the key off, then turn the key on again for it to start?

Yes, the engine will start. It starts every time you try starting it with the key in the off position, but it only stays running for a couple of seconds, 4 seconds at the most. If you don't turn the key off all the way most of the time, not all the time the engine will just fire off a little but doesn't run. Sometimes it will run for a couple of seconds. Thanks for trying to help me.

Still try these things, it'll help confirm or eliminate some possibilties
But I suspect it's the ignition switch which is opening the relay (shutting off the fuel pump)
Checking the FP at for spark @ no-start can help confirm this
And it's always a good idea to check the codes

Follow slickshifts advice and I'll second the motion to suspect the ignition switch. After starting the engine, hold a light finger pressure on the ignition key to prevent it from returning excessively to beyond the 'run' position.

air flow meter

Do you have the intake air ducts on and leak-free?

Many of the older pre-hotwire mass-air flow meters have a fuel pump switch. See if the meter has a door you can push open. If no, this does not apply.

If the flap does not open after a few seconds, the pump loses power. If the flap opens but the switch is no good, the pump loses power. The car senses no intake air so it does not need gas and maybe prevents flooding or leaks in an accident.
