Hi all,
I have an '81 Spider (FI) and I'm on my 3rd fuel pump/filter and it won't run (yet again). I've gotten more mileage riding in the tow truck than in the car behind it:bang:.
So far I've replaced all the fuel lines, injector hoses and seals, air flow meter, and combination relay. I also had the fuel tank cleaned by a radiator shop.
I found a diagnostic guide and started trying to locate the problem in the FI circuit. This is where I get real confused, real fast. The combo relay seems to be feeding the fuel pump via terminal 88d. The power appears to come from terminal 88y (white/brown wire with inline fuse). The fuse was also blown but I've replaced that. What I found strange was that the voltage at the relay from terminal 88y to ground reads 12.25 volts, but the voltage at terminal 88d to ground is only about 8.3 volts.
Am I looking in the wrong place? Any suggestions on how to proceed would be greatly appreciated!
Thanks,
SeanKB
