A few days ago I went to start my car to go to work. It cranked but would not start, I noticed my fuel light was in and the gauge read empty.I assumed somebody has siphon the gas out of it, seeing as how it had a half of tank when I went to bed the night before, I put gas in and nothing changed, I checked the fuel pump relay and fuse, both were fine, so I removed the seat to inspect the pump, when I pulled the electrical connection gas started pouring out of it. I disconnected the battery, and removed the top of the pump, only to discover that the wires had burnt a hole into it, I replaced the pump, connected the battery and primed the system and tried to start it. No crank, all the lights gauges accessories worked but no crank. First I checked the anti-theft system, that was not the issue, the check engine light has always been on, for an oxygen sensor, I used my OBD2 and pulled the codes, nothing new, I pulled and visually inspected all fuses in vehicle and tested them with my meter, all were good, I tested all the the relays in the vehicle, all had about 72 ohms, all functioned properly and had continuity between leg 30 and 87/87a. Then I checked the starter by jumping the wires, it turned over and started properly. Next I tested the starter relay location, I had constant power at terminal 30, but no power on 85 or 86 (somebody was holding the key in the start position when I tested it), I then checked the the ignition switch and the actuator pin, both were in good working condition, I have power going to and leaving the switch. I inspected the transmission shifter and cable thinking it was the transmission range sensor. Everything checked out, I checked for continuity between the fuse box and PCM through the yellow wire and green/orange wire, both were good. I called the dealership, and they said it could be the key, I had it tested, it failed, I had a lock Smith come by and make/program a new key. Did not work, I have checked every possible ground connection on the vehicle, and cleaned all that needed it, all grounds have less than 2 ohms, I tested all power connections and all had less than 3 ohms. I have done everything I can think of except checking continuity of the wire leaving the ignition switch. I have not been able to find a valid wiring diagram that says where the ignition switch wire (hot on start) goes to from the switch, it does nit seem to go directly to the pcm and if it does, the wire color must have changed because there are no wires at the pcm that match the wires at the ignition switch. Also the right side daytime driving light and the high beam do not work, there is no power coming to the wires, there is continuity between the light and pcm, the left side works fine, though, I am worried the pcm might be bad, but I was to exhaust every possible thing before I condemn it, any ideas as to what it could be or what I could do to figure it out?
