I don't know. I suspect the armature wobbles in the bearings at
Or the brushes are at the end of their travel.
Like you said, you may not get a low reading until the pump acts up.
But then you might. If it's under 40 psi, I would probably replace
it anyways, considering the year of car.
Also, don't forget to check the regulator! It could be the problem.
I just put a gauge on the rail. It reads a steady 34 PSI at idle.
So, where's the pressure regulator?
On the supercharged, I don't know. On the non-super it's at the other
end of the fuel rail. There is a vac hose attached. Vac opens the
regulator and allows fuel return to the tank. No vac = closed.
Pull the hose off, if there is a strong fuel smell in the reg or hose,
the reg is bad. With your fuel psi gauge attached there should be an
increase in psi with hose off - from 34 to ~50 or so. 34 would be a bit
low for a non-super engine. 44 would be better. You will need to look
up the specs for your engine - Chiltons, etc.
You could check it off the vehicle by pressuring up and seeing when it opens.
I have never heard of these people before but the article is worth reading:
Another symptom, perhaps related to the herky-jerky thing. Now, after
the cold engine the RPM oscillates. It first runs up to a little over
2000, then drops
down to below 1000. After repeating this a couple times it settles
down to the normal cold idle
of about 1100. It began doing this after I had fiddled with it a bit.
I took the vacuum
line off the pressure regulator to smell it and inspect it. There was
a faint odor of gasoline.
The line looked ok.
Could this be related to the herky-jerky thing?
