Today is day 4 of being a Delorean owner and I already have an issue where the car won't start. In all honesty I figured stuff like this would happen so I'm not too upset, but I hope you all can help me troubleshoot. I'm going to give you a little background on the car because I'm not sure if any of this info is relevant. The car was always starting great, although I bought it knowing it had a WUR problem. You had to let the car warm up for roughly 5 minutes or it would die on any constant acceleration. Sometimes if you blipped the throttled you could get it to eventually rev up during the warm up period. After warming up it would run great and didn't have any warm start issues. Yesterday I removed and tried cleaning the screen on the WUR (but in all honesty it wasn't that dirty). I put it back and had the same problem so I figured I'd have to have it rebuilt. Last night I accidentally ran down the battery while playing the radio and working on cleaning the car. I didn't think I had the radio on long enough to kill the battery (maybe 2-3 hours) so maybe there is something else wrong? Anyway, I couldn't get it to start last night, even after jumping the car with another car. It cranks great, but that's it. No attempt to even start. My first thought was fuel pump, so I read up about testing the pump, jumped the RPM relay and heard the fuel pump turn on right away. I'm getting roughly 9 volts from the fuel pump contacts. I can't find exactly how many volts it needs so I'm not sure if this is where it should be or not. I know the fuel pump had been replaced, but it was still the old style pump. The car wouldn't start even with the fuel pump running.
Four other recent observations I had made was that a wire was unplugged in the drivers side rear wheel-well (picture attached). I think this might be a ground? I plugged it back in on Friday night when I adjusted the parking brake and the car still ran fine on Saturday morning so I don't think this was it, but still curious as to why it was unplugged. The second observation I made (just this morning) was that it looks like there is a ground wire that isn't connected to anything that was hanging behind the engine. (Pictures attached) It is possible I bumped this off somewhere when I was tracing the vacuum lines, but it definitely wasn't secured on properly to a bolt. Could this be causing the no start issue? The third observation is that there is also a plug behind the engine that isn't plugged into anything (picture attached). I don't see anywhere that this should be plugged into and I don't think it's ever been plugged in since getting the car so I'm not sure if this is the issue. Lastly, I found a tiny bit of oil on the ground and see that it is coming from a plug on the driver's side rear of the engine block bolt/plug. (picture attached) It looks like that there is a wire going into it. Not sure what this is or if it could be causing my issue either.
Any advice and/or help is greatly appreciated. Thanks!
