I was out messing with my "new" B2 today. I replaced the postitive cable and spliced a new plug on the coolant sensor.
Anyways, last time when i noticed the screwed up postitive cable i noticed the fuel pump wasnt priming, and obviously wouldnt crank.
After i changed the cable it cranked great....but still no fuel pump prime. The wireing to the relay is pretty spliced togther (not by me) but i checked, had 12v to one plug, like 9.5 to the others, and 1 that had zero.
I took a paperclip and shorted the 12v terminal to the 0 volt one and the pump fired up. So i figured the relay was bad. I plugged the relay back in (so i wouldnt lose it)As i was heading in to turn the key off i noticed the damn negative terminal looked loose....so i twisted it a bit and the fuel pump kicked on. I looked down and noticed by where the neg hooks to the frame then heads back the wires are all exposed and corroded.
I wiggled the cable further down and got the pump to kick on a few more times then it wouldnt any more...also one time after the pump primed i tried starting it and it cranked fine....tried to start a bit...but wouldnt. It was after that i could no longer get the pump to run.
My question is....why...or what...would allow it to crank normally but not allow the pump to run...or actually start?
I ordered a new cable...but do i have another issue going on? Was it a fluke?
i dont understand electrical.
