....at least now I've got fuel pressure from the main pump.
I replaced it after measuring and finding the current draw to be around 2.2A when I would power up just the main pump.
I did get a chance to go out to a 240 of a co-workers and measure his main fuul pump current and his was 7.0 Amps. The Haynes manual schematic says it should be 6.5 Amp. My new pump measure 8 amps.
My new pump ($154..AutoZone) was identical to the one I replaced (PN: E8123)
Of course my hopes were up that the car would now start but, alas, it does not.
I haven't measured the pressure but I can tell from the spray that comes out of the filter inlet that there is significanlty more pressure than I had on the old one.
SO now my next question is what can be keeping the fuel from getting to the intake.
(Recall that the engine starts when starting fluid is squirted into the intake manifold and I'm pretty sure the injectors are firing. When cranking the car if will not even "hit" except on the starting fluid.)
My next question is: "Shouldn't there be some fuel flow back out of the "return" line on the firewall running parallel to the inlet side which contains the fuel filter?"
Perhaps that is not what that line is for but could someone tell me if that line should have at least some fuel flowing back to the tank or wherever it routes to?
When I open that line there is no fuel at all. Not even a drip.
I would greatly apprecaite any help with understanding the "fuel distribution system or module" or whatever the output from the fuel filter goes to.
I also have a high pressure at the cold start valve when compared to before I changed the fuel pump, and I am curious as to why the engine won't at least start if only for a few seconds, on the cold start fuel alone. However, I am not sure if the cold start valve ever worked since my girlfriend has owned to car, but I'm gonna check it tomorrow and see if it is squirting into the manifold but even if it isn't the car should still start, or at least hit, eventually while cranking continuously.
Any insight, comments and ideas would be greatly welcomed and greatly appreciated, especiial in regard to failure modes of the "fule distribution module" or whatever it is. Perhaps someone could email me or fax me a copy of the relevent pages of a Bentley manual.
I'll keep plugging along and keeping you guys informed of my trial and tribulations and when I final succeed, I'll share with the forum my final findings.
Thanks for your time and thanks to all who have responded to my previous posts.
