Weird optispark harness questions
When I jiggle the opti connectors (delteq) it makes a whole s*** load of relays go off, my injectors start clicking, and the fuel pump starts priming. So im guessing if I fix whatever that problem is it will start....
Ok I pulled the engine harness out last night to rewire the injectors because my old ones were not matching and frayed. So I fixed that all along with a new TPS, MAP, ALT, IAC, IAT, connectors. I started it last night and it ran (idling) and revved up smoothly. Now, I had to pull the harness again because I made #2 injector wires too short. Fixed that and noticed my VSS wires were frayed. Fixed that. Now car will just turn over and my battery will NOT hold a charge. Wont even turn over with the 50Amp setting on my charger.
Also, I have signal voltage (5v) at all my repairs, and 12v at all injectors.
Thanks

Update. I checked the Opti connector. and I wiggled the harness coming form the delteq, and NOTHING, wiggle the opti harness, NOTHING, so theres something weird in the PCM side of the opti harness
Also, this is ALL occuring with the key in the ON position. Something is also draining the battery becasue with the harness plugged in, it barely primes the fuel pump, and as soon as I unplug it all, the multimeter reads over 14v with the charger on it
