I have a no-start situation with my '92 945t. It wouldn't start last Friday after my wife parked it at the curb in front of the house. After getting it pushed into the garage and running some quick diagnostics, I replaced the fuel pump because the existing one didn't sound good and showed high current draw (about 12A for both pumps). I also didn't seem to have fuel pressure at the rail.
The replacement pump is a Carter, and seems fine except for the lack of a check valve. There is fuel at the rail, as evidenced by using a tire pressure stick gauge on the Schrader valve between #1 and #2 intake. I get the prescribed liter of fuel in 30 sec of cranking from the FPR return. This works both with the fuel system relay in place, or with a jumper from 30 to 87-2 to force the pumps to run. I can hear the in-tank pump running, the in-tank is new and both pumps together draw about 9A. I think the fuel side is probably OK, although I don't have a proper gauge set.
I have spark-- I pulled the #1 wire, put a plug on it and grounded it on the intake and cranked the car-- I see good spark.
I checked the OBD system, and get 1-1-1 on sockets 2&6.
I had a bunch of radio suppression relays and 2 used power stages that I have swapped in. Still no start.
The cap and rotor were new late last summer, the RPM sensor was replaced last spring, the timing belt has about 8K km on it.
Any suggestions about what to try next? I need this car on the road again!
Thanks in advance!
