I’ve just been doing a bit of reading on s14.net and have come across this check for the fuel pump. I know Ian Haynes has mentioned this to me before, but I thought that if I post it on here I might remember to check this out in the future, as I fear my fuel supply isn’t quite right.

“Locate and remove the fuel pump relay. Flip the relay over and look for T30 (12V constant) and T 87(power to Fuel Pumps). Look for the corresponding terminals on the relay plug and jump them. The Main Pump should run. If it does not, the wiring to the pump is shorted or more likely, the main pump is dead. If the pump runs…follow the OBC bypass procedure.”
