2008 4 cylinder AT. Was running fine with no issues. fires/starts then stalls immediately. No ability to raise rpms at all. Fuel pressure 65lbs. (and holds pressure) at fuel rail. Changed IAC, Changed TPS, pulled first O2 sensor to check cat. No change. No codes. Thinking Camshaft position sensor, but no codes. I would appreciate any thoughts. Thanks

If it fires and then stalls every time, you may be losing your signal to the computer that the engine is running. The computer will disable the fuel pump(or they did before anyway) after the 3-5 second run when the key is turned to ON. It will then re-power the pump once it gets the signal from the crank / cam sensors that the engine is actually running. To find out, you could jumper the pump to apply power continuously, then try to start and see if it keeps running.
I would think there was a code if one of the sensor signals was missing.

Check oil pressure sensor by oil filter and see if it is full of oil. They go bad. Replace it and do not overtighten. It is pipe thread. Dont ask how i know not to overtighten.
