Electrical problems- No Fuel

thedude · 11-04-2010, 09:21 PM

ok, so i've got the new fuel pump in, but still no power to the pump. i've checked all of the pins on the "fuel pump relay" on the passenger side under hood. none are reading any voltage whatsoever in relation to ground while the key is on. any idea what would cause this?

thanks for the link, bill.

cameroonski, where is the efi relay? i can't locate it on the diagrams or on the vehicle.

the check engine light does come on. the fuses in the drivers side kickpanel all look good save for the two 7.5A fuses. (the one for the gauges went out, and when i tried to pull the one for the dome lights, i dropped it. lol.

also, the EFI fuse in the under-hood fusebox is getting 12V, and is good.
