If you went to that extent and still haven't located the issue I would suggest two things. First, check and see if you're ECU has gone bad. Try to locate a temporary donor, install it, and see if that's the problem. If that isn't it, you may have slipped a couple teeth on your timing belt. When you did the check your referring to on the timing belt I assume you lined up your timing marks, correct? A buddy I had an identical issue on his GSR and I had to argue back and forth until he decided to line up his timing marks and found that to be the problem. Good luck!I am having the same problem, but i have delved in much deeper into the problem. I had diagnostics run, bought a whole new distributor, which replaces the ICM, the IGNITION COIL, the CKP (Crank Position Sensor). Checked the main relay, the fuel pump, the fuel filter, the timing belt, the relay's to the whole system. Did a full obdII scan and found nothing on the ECU. Reset ECU and tried again. no luck. Checked injectors, they're spraying. Checked spark, great spark. Checked grounds, all secure. Checked everything!!!! So pissed. this is my daily and I need it running. If anyone has any input it would be greatly appreciated. Thanks a ton.
Did you check your ecu like I suggested? I doubt all or multiple injectors clogged at once. Even if one was clogged, the car more than likely would run. I think if you correctly went through and checked everything you claim then your ecu is shot. It isn't rare to have an ecu go bad. Also, I assume you've already checked relevant fuses, correct?Anyone?
