Was the hole in the cam pulley lined up with the notch on the top of the front bearing mount when crank pulley is at TDC?

Was there a timing tang extending from the circumference of the pulley (see below)?

Was the wiring electrical interference shielding damaged?

Yes the cam was lined up with the notch and the crank was TDC.

The cam timing tang did not look as the one illustrated in your link but a smaller one was there.

I found no damage on wiring or connectors.

I did check the resistance to the crankshaft sensor it was 2,133 ohms cold and the specs I have state it should be b/t 985 to 1,600 ohms.

Could this be causing the cam positioning sensor to appear to be the problem?????

Anyway please let be know what you think. I'll be gone for a week and will work on it when I return.

Thanks again

The crank sensor has its own trouble code.

Check wiring/sensor resistance at the ECU wiring connection. Should be the same as sensor.

Try checking for a sensor signal using the voltmeter method. Do you know of any one with a oscilloscope?

Toyomoho, thanks for all the suggestions.

I thought it over and concluded that you thought it was a timing issue and I thought it was a timing issue. So I took it apart (again) and even put on a new timing belt, lined up the timing marks, and put it back together. Now it runs fine. I must not have got the timing right the 1st time.

The check engine light is still on; I'm guessing I just need to have the code cleared out.

I must say it was hard for a slow big handed man to get those bolts out and in again.

Thanks again

The second time was the charm. Good job!

The computer will self check, if fixed clear the code.

If having a code reader, clear codes and determine if it comes back.
