New problem with the efi conversion!!

Post by B.O.B. »

So I am trying to fine tune the beast know and all of a sudden the ele. fuel pump won't kick on when I turn the key. Check the power going to the fuses and relays and the box is getting power. The relays are not kicking in (reworked harness from KOLIBAR). The other weird thing is that now I have a wire under my dash that is overheating and gets really hot. Never happened before and i dont think that the two are linked but the problem is now happening. Any ideas what It could be?

Is the under dash harness original? If so there is a resistor wire in the harness, it is a specific length and if it is cut, spliced or damaged, it can overheat and cause all kind of problems.

I would rather not mention how I know this, but I do...

It is the orginal wiring but nothing was spliced into it. There were 4 wires to hook up and 2 went straight to the battery and 2 went to the solenoids.

Re hooked up all the wires to the battery and so forth and the overheating wire is gone and fuel pump is working. Could this be a bad solenoid? Don't really want a problem that just shows itself and then goes away.
