Check your grounds

I assume your battery is still at 13V?

it's a new battery i bought a couple weeks ago, everything has 12V except the injector plugs.

i'll check battery volts tonight

Well there is your problem, Now the real question, Why.

Well my friend told me to get an eBay fuel pump. So now I ordered a real one. Hopefully that's it. But I doubt it would do anything since the injectors are only at 6v

Fuel pressure is at 2psi...
Also volt meter to the wiring harness ignition clips only have 6 volts

So it must be low fuel pressure? Do you have a new regulator? What if you cycle the key/fuel pump a few times. Will it build enough pressure then?

Do yourself a favor and get a nice fuel pressure kit that will connect to the schrader valve.

checking the fuel pressure tonight. i cycled the key a ton of times and still nothing. i had the fuel pressure kit on it like a month ago when it started the last time, and it was at 60psi. i guess we will see tonight what it's at. if it's at the 60 then it's injectors.

starts on starting fluid.
took the injectors out and they're spraying but it looks weak
drained all the old gas out and put new gas in it hoping that would fix it.
still the same.
going to get a fuel pressure gauge tonight and test it again.

If there's an injector wiring problem or blown injector fuses, the injectors won't fire.

Using the starting fluid is an essential troubleshooting step to determine whether the problem is "upstream" or "downstream" of the fuel delivery.

If the engine fires and runs on starting fluid, that means that the crank triggering and ignition systems are working correctly and the problem is with fuel delivery.
If the engine doesn't fire on starting fluid, that means there's a problem with the crank triggering or ignition systems.
If your not smelling fuel after extended cranking, you're probably not getting fuel into the engine at all.

i'm getting the PCM back tomorrow so i'll get a can and try it out

^ buy something similar to this and plug them into the injector harness. Turn the car over. If they don't light up, your injectors are not getting signal to fire. Regardless of how much pressure is at the rail or if the pump is working, if the injectors aren't firing no fuel is getting into the engine.

As someone mentioned earlier, spray a quick shot of Ether into the throttle body (don't over do it) as your cranking the car. If it starts, you have an answer and a defined system to troubleshoot.

fuel pump primes and i took the hose off, put the hose in the bucket turned the ignition on and let it rip. fuel was coming out into the bucket.

and i know i have spark for sure.

I don't think you get it.... so good luck dude.

Take the rail off put each injector in a water bottle hit the key you will know pretty quick

[Reyhan335]

If the injectors are not firing then u still wont get fuel into the engine.

I didn't check injectors because I didn't think all 8 would go bad at once.
