Ok so I'm working on a 1971 914-4 which from another thread it appears to have a 75-76 2.0 912E L-Jet FI system on it from the PO.
I have plumbed new fuel lines through out the car, cleaned fuel tank and it has fresh gas. I went through the dual relay and redid it all which I did find one wire on the wrong terminal from the diagram I had. The previous symptom was that it would start and then die when the key was released. So I threw a battery in it and yep that's what it does. It will fire and run momentarily then die. First issue is that I don't hear the fuel pump run. It's currently wired from the original harness with some PO adds ons like a fuse. It is not wired to the dual relay but back into the harness that runs to the relay box. I put a meter on it while testing and didn't ever see any voltage. So to make sure this wasn't the issue I hot wired it to run off the battery while I tested that. But that didn't fix the main issue. Next item is that the ignition switch looks like it's from the movies and has been hot wires. Of course they did it through and around the knee pad so I'm digging into that now. I unwired it so I could remove the knee pad. From the ignition switch area there looks like 4 wires. red, red/black stripe, a black and a gray. The gray one wasn't hooked to anything. (IMG:http://www.914world.com/bbs2/uploads_offsite/www.mikesjunk.com-19423-1450654793.1.jpg) From the harness there were 5 wires. The Black/Yellow and Blue/Yellow weren't hooked to anything. (IMG:http://www.914world.com/bbs2/uploads_offsite/www.mikesjunk.com-19423-1450654793.2.jpg) I'll start researching the wiring diagrams but anyone want to post a response to short cut this would be appreciated. Also the key/cylinder feels pretty bad so anyone recommend someone who can go through it? I saw a guy on ebay listing this but looking for recommendations as it will need something eventually. |

LOL, it seems to be a matter of perspective. Guess when the harness is on the bench I know which way to count but not when it's in the car. Figured that out when I had it laying on the bench again. So here's some more updates.
As for the fuel system here's it is back to how I received it but with new hoses. So you can see I have two regulators? (IMG:http://www.914world.com/bbs2/uploads_offsite/www.mikesjunk.com-19423-1450981393.1.jpg) I've updated the parts list with some more numbers. (IMG:http://www.914world.com/bbs2/uploads_offsite/www.mikesjunk.com-19423-1450981393.2.jpg) Here is my harness pin out. Note that mine does not have 2,3, 18 for the throttle but only 12 goes to the throttle switch. The rest seem to line up...when you count right.

After I got it all back together I tried again and still starts right up and then dies. (IMG:http://www.914world.com/bbs2/uploads_offsite/www.mikesjunk.com-19423-1450981394.4.jpg) |
