After having tranny repaired a couple of days later several things turned themselves on after driving about 4 blocks including heater. Stopped and car would not start. Jumped and no problems. After starting several more times. No Start. Nothing. Changed starter. Now turns over no fire. Did the igniter bypass test both coils fired. Cam sensor, crank sensor and relays check out fine. At a loss. Please help. Computor will not communicate to throw a code.

    Checked 'ALL' fuses and anything that looks like a fuse with a tester? Computer must be able to talk to a scan tool, or it ain't going to run!
