I have been troubleshooting my daily driver for 4 weeks now and cannot get it to start. Car has 242k miles (still new) and symptoms started one morning in October when Car started stalling and shut down on me. Was able to restart and drove home in limp home mode- if I gave it more gas it will stall, so kept my foot off the pedal and got home.
My immediate though was AMM and I cleaned it, put it back on, car run perfect, but when I was about to leave the house- no start, so I started troubleshooting - changed RPM sensor as wires were showing from insulation, put new distributor and rotor, plugs, swapped the powerstage and the coil, still nothing, then all of a sudden spark showed up but still no start, checked the fuel pump and FPR, unplugged return line of FPR gas flows strong, swapped FPR with a spare, nothing... hooked up Noid lamp to injectors and pulse was there too, along with the spark, but still no start, drained a plastic bottle from gas tank and compared the gas with another plastic bottle - checked for water, seemed normal, was about to drain the tank anyway and fill with new gas, but then I lost spark and pulse...Oh took the ECU out and plugged it into my 780 230FT and car ran fine, also swapped ignition computers ??? still nothing
Right now I have +12V at coil even when the key is out of the ignition, ( and wire is pulled from the coil) swapped few radio sup. relays, swapped AMM with the 780 and still nothing, took apart the connectors at the strut tower F and C LH and also the other two on the RH side- silicone was bad and will need new ones, but for the time being, cleaned the wires and plugged them back in. As of right now I am suspecting a short somewhere, any thoughts?
