Electrical Problems
#11
A loose or bad ground will cause all kinds of havoc. I replaced mine from the battery to the back of the engine when I started having weird electrical problems. Headlights would automatically close, sometimes start, sometimes the display lighting would flicker. The regulator on the alternator can go bad as well, not receiving a good ground, or a short circuit if something is hooked up backwards even if a new stereo is hooked up wrong. The other electrical issue I had besides the bad ground from the battery was the DME. It had a mind of it's own. Car would start right up and after about two minutes it would die. Sometimes it ran fine for days. I had the DME tested and the tech found three bad components and replaced them. DME repair was $100.00 Now it runs great. Prior to that I replaced the fuel pump relay, fuel pump and the reference sensors. Only thing left was the DME. Mine too is an 87 924S.

porsche 944
Hello Guys I am new to this forum and happy I found it I bought a 944 that just lives in the shop but when it runs I love driving it My recent problem is I have a red wire that comes off the secondary fuse panel where the fuel pump fuse is my guess it is either 12 or 14 gauge solid red that goes somewhere and i have no idea where this wire attaches? It appears to be the only solid red wire under there and the fuel pump is not working . Any ideas would help and ideas on where to find a goood clear wire diagram would help beacause the front harness needs to be replaced as well Thank you guys greg

You should try searching for a driver's manual. Maybe that can help you in some way. My dad had some issues with his Land Rover. I downloaded a manual and found the exact answer to what was bugging him.
