It's the cylindrical thing about 2/3 of the way back Posted by RS [Email] ![]() ![]() ![]() In Reply to: FPR....what is it, where is it, & how do I test it if.., Jake in Atlanta, Thu, 23 Sep 2004 19:34:00 Members do not see ads below this line. - Help Keep This Site Online - Signup |
of the head, with a vacuum hose and two fuel lines attached to it, one of which goes to the back of the fuel rail. The picture below will give you a good idea of what to look for.
The easy test (but not a foolproof test) is to take off the vacuum line that goes to the FPR and see if there's gas in it. That means that the diaphragm has ruptured and, in that case, it's daid fer sure.
That said, the spring inside can weaken and dump in too much fuel.
A couple of things to look at before you get digging into fuel delivery:
Are the spark plugs fresh?
Are cap, rotor, and spark plug wires recent?
Is the vacuum hose between the intake manifold and the vacuum port on the FPR all connected?
I've had some no-start conditions with wet plugs. Drying the plugs didn't help, but fresh plugs were an instant cure.
Where are you located in ATL? I have a spare FPR you can try.
