I have an 89 rs 305 tbi. Lately it has been hard to start and the code 54 has came up twice (low voltage fuel pump). It only has 5 volts at the pump but 12 at the fuse. Is there something that regulates this voltage or should I be looking for a short?
Have you replaced the Filter lately, it is the best place to start. My old S-10 was getting lazy in the starting department, Finally got around to changing the filter, it was plugged solid, new filter, starts like a new truck.
