SOURCE: Fuel pressure regulator

Very easy if you have the new one just look at how it is mounted, most times just a couple of retainning screws and it comes right out, bleed the fuel system of pressure before you take it out or put a rag over it, there will be about 40 PSI in the fuel rail.

30-40psi. one thing to check first is the vaccumm hose at the fuel pressure regulator, take it off, if it leaks fuel, replace the regulator. when the engine is running you should have approx 30psi, with vaccumm hose off, approx 40psi.

When you turn the key on excessive fuel flows into the air intake. its a 1989 6 cylinder 3.1 fuel injected


You could have either an injector that is stuck open or a fuel pressure regulator that has developed a leak. A leaky injector will usually only leak fuel into one cylinder as it is located just above the intake valve in the lower part of the intake while a leaky fuel pressure regulator will leak fuel into the front end of the intake manifold [behind the throttle plates] and the fuel will acuumulate throughout the upper intake plenum. When a fuel pressure regulator develops a leak the fuel that is escaping from it flows through the small 1/8" diameter plastic vacuum line which goes from the top of the regulator to the intake manifold. Even a trace of fuel in this line means the regulator is bad. I've seen both leak items leak but probably replace 10 regulators leak for every one injector. Good luck, hope you find your problem!

Stalls when hot


Try a crank sensor. It's just above the oil pan center between the engine and transmission. Look and see if the old one is cracked.
