The vehicle cranks but wont start. I have replaced both cam sensor. The crankshaft sensor and battery. Per the computer I have 63psi fuel pressure. I can crank it over but wont start. Every now and then it will start for just a second, but wont stay running. I have tried starting fluid and still will not start. Timing belt was changed 20,000 miles ago. No codes in the computer. Cannot be sure about the security features. I have tried both keys and still no start. I have always said I am a pretty good mechanic, but this one is kicking my butt.

Also, I know it is not the chip in the key. I tried a non chipped key and it wont even turn over then.

Yes and it is hit and miss. When there is spark it starts right up. I have the ECM at a re-builder now having it checked.

Yes and it does not show any rpm's while cranking. Which is why I decided to have computer checked after replacing the crankshaft sensor.

Computer was tested and the processor was bad. But since it is isuzu they can't rebuild it. I got another one online but I have not gotten the chip in the key programmed so I still can't start the car
