I finally got my Raider to give me an error code from the ECU. It is still sputtering, if I hold my foot on the gas, it eventually dies. Then the check engine light comes on. I checked the code with a volt meter, it gave me 42, which is Fuel pump. Does that mean the pump is bad? Could it be the fuel pressure regulator? How do I check these two things to see which one is bad? What would trip the Fuel pump code?

I just want to tell you both good luck, and we're all counting on you.

Survey says, its the fuel pump. You can pull the hatch in the back and see if you hear it run when someone turns the key to on, and put a test light on the plug to see if it lights up. The pump only gets power for a second when you turn the key though.

I know the pump works, well sometimes, because the truck runs fine for a little while. The wires look good. I guess I will get a new pump. I dont want to go spending money if that is not the problem.

well, then, put a meter on the fuel rail, and see if it's holding pressure (it should fluctuate with inlet manifold vacuum, but stay pretty high).
If not, then tee off before the regulator to see how it's doing (this is a major pita- mitsu has a kit, but I doubt mere mortals could get their hands on it)- if that point holds steady (high) pressure, it's your regulator. If not, it's the pump. Put a meter on the pump power terminals- sometimes the relay will only work intermittently...

Hey Sparkem,
I may have dropped the ball a while ago... I've been pretty busy lately! Didn't we talk about me sending you an MPI relay to try out? If you still want me to send it to you, PM me and I'll get it out asap.

I tried the MPI relay out of the montero and it did the same thing. I bought a new fuel pump and that seems to be the problem. It has not messed up yet. I hope it stays that way. Thanks for all the help guys. <img src="/forums/images/graemlins/cheers.gif" alt="" />

Guess what messed up today...... POS. It is giving me the fuel pump code and now the ECU flatline. Dammit. I got that ecu off of ebay. I hope that works.
