Fuel pressure

[rickta24]

where could I find what the fuel pressure should be? I'm trying to figure out if my injector pump is bad.

grab the engine manual from the sticky at the top of the forum, it has troubleshooting steps.

thanks. I tried to last night but the file was too big for my phone. I will download it when I go into town.

its a several Mb pdf file, but should have all the info you need to start the troubleshooting process.

ok i looked and the only thing i could find is on page 156 of 267. but i still don't understand. looking for what the fuel pressure should be. im going to put a fuel pressure gauge in front of injector pump and then after injection pump and see if i can eliminate it that way. but i can't find what the fuel pressure should be.

in front of the pump, the lift pump on the side of the block should be putting out ~5-7psi.
you dont have a guage that will read the pressure on the injector lines, they run at ~1900psi
