I checked asd relay .ignition fuse fuel pump relay. Pcm fuse. Just went for runnining ones. Will check others tommarow. I believe it was still no check engine light when unhooked.

"It is also reading empty on the gas gage while having fuel in it. When I turn the key I can hear the fuel pump running but it doesnt stop running idk"

--------------------------------------------------

Just for the heck of it pour a couple of gallons of gas in it and see what happens.

It just seems strange to me that the fuel pump keeps running.

The fact that the fuel pump keeps running I think is key here. Since it is only supposed to prime and then stop, and given the strange other behavior, I vote for a short or bad ground somewhere.

If you're not getting a CEL lamp check from the PCM, the PCM is not working (assuming you know the light was working earlier). Since it is sending a ground to the fuel pump relay, it's not completely dead. You can reset it by disconnecting the negative battery cable. After you disconnect it, turn the ignition to start to discharge any residual voltage. Then, take the keys out and put them in your pocket. Then go out and clean your battery cables if you haven't done so lately and reconnect them.

As a long shot you can try swapping the ASD and fuel pump relays with the horn and intermittent wiper relays.

I did try the second one. Had yad battery unhooked but never had turned it on while unhook will try it. Could it be a possible alternator failure?

take battery cables off, pull plugs on PCM, clean them, reassemble and try it.

have you tried spraying some instant start down the TB to see what happens ?

Have you checked for spark and for fuel at the rail ?
