Hey all,
My 1992 FJ80 has been having some trouble starting. It takes a bit of time and when it does turn over, the rpm's are low (200's) until I give it some throttle. I've done the easy stuff (new battery, new plugs, cap and rotor, new fuel filter, new EGR modulator, and new air filter). I had a feeling it might have a bad fuel pump so I got a test kit and hooked it up.
When I flip the key on, there is no pressure. Zero. But when I try to crank, it fires up, eventually with some assistance from the throttle. Still no pressure on the gauge. Then over time, the pressure will build. The longer I keep it running, the higher the PSI goes until it reaches ~40psi.
I attached the test gauge on the cold start injector at the top of the intake manifold. Would this be a bad fuel pump or is the problem somewhere else? Maybe I'm not testing the pressure properly?
Appreciate the help, thanks!
