Is there any *easy* way to determine the difference between a dead fuel pump,
and the dreaded wiring splice issue? This is on my '95. I get code 55
whenever I check the codes. That's the only code, but it seems that the
computer is alive at least. All the other electrical stuff appears to be
working, as far as I can tell. I'm guessing the fuel pump is gone, but I'd
rather not be replacing parts that don't need to be replaced.
It's been having problems starting over the past couple of weeks. First it
took a lot of cranking to get it going. Then it wouldn't idle for about the
first 30 seconds after starting. This morning, it wouldn't start at all and I
had to steal Norah's truck to get to work. (Figures, I just filled up the tank
last night two miles away from home.) I couldn't detect any pressure at the
fuel pressure test port. I don't have a gauge, but I pushed in the pin and it
went "pft" and no fuel came out. I don't hear the pump either. What's weird
is even with the way it's been running, it's been getting awesome MPG lately.
It seems like maybe it just hasn't been pumping as much fuel as it should even
when it was running, does that make any sense?
I know I can check for power at the pump connector once I get the bed off, but
I was hoping there was an easier way to tell the difference before I get that
far in to it.
Thanks,
Jason
