QuestionQUESTION: hi. I replaced the fuel pump and filter and engine ran fine. now will not start and no voltage at pump. I would like to find the relay to replace or test by shorting out 30 and 87? (right)? I gad the fuse box translated into English. all fuses are good.
I will greatly appreciate all help.
ANSWER: Id retrace my steps , if after the work it ran fine, and now it does not suggests something related , try running 12 V to pump direct to make sure it is OK and then look for fuses or open shorts. Relay I believe for that car is the basic "cube relay"
