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. |

Thanks for stopping by Tim. The chart is basically what I pulled from some of your replies to a similar topic. Thought it would be best to knock out the things you were probably going to ask. I may need to layout the whole harness wiring as it doesn't seem to line up with some of the pins you've pointed to. For instance there is no terminals in hole 8.
Also, to be clear my fuel pump is not currently wired to the dual relay (probably wired like a 71 D-jet) so that pin is open on the relay. Not sure if the jumping of terminals will get it to turn on since it's not part of the relay. Mine is wired into a factory looking harness that runs in front of the engine over to the relay/ECU area. I did jump it out to a battery previously to see if the car would run, but it would still die upon release of the key. As for the fuel regulator if what is pictured is correct then should I also have one with a screw? I have both in the system....remember thread title is Frankenstein so not sure what I have from the PO and various people that were under the hood. I also tried applying a vacuum to this and did not get any flow through it. With it out of the system and the screw regulator one still in I have 35psi and flow back to the tank. If I put this back it I will have 75psi and applying a vacuum won't open it. |
