Crank no start issue 1993 Toyota pickup 22re/1993 Winnebago Warrior.
Went from being reliable to randomly not starting one day, sat for a few weeks then started right up randomly, then shut off about 3 miles down the road, wouldn't start for a few minutes then started and got me too my destination. Since it has been sitting it has not started again, no fuel pump hum when I put the key in the run position, jumped B+ too FP and hear pressure in the rails and hum in the tank still would not start on jump. Checked EFI and it may be bad not sure if I could feel the click, swapped with headlight relay and still no start. Went to the auto parts store and was given a relay w the part number "T05 SH121" still not sure if I could feel the click with this relay in, but still no luck. Also tired headlight relay in EFI and new relay in headlights place and it seemed too function as without the headlight relay it it wouldn't crank before, but still no start. Jumped the diagnostic so I could get a engine code and the code I was given was '12'. Not sure what too do from here as I have little too no experience working on vehicles, should my next step be too check the circuit opening relay? Anyone who knows what their talking about that could help would be greatly appreciated.
