Answer
Hi Dennis,
Are you getting spark? How about sounds from the injectors while you are cranking it? Have you checked for pulses from the cam/crank sensors when you rotate the engine by hand (should vary between 0.3 and 5.0V) measured between black/light blue and the tan/yellow (cam) and the gray/black (crank) wires). Is there any sign of ignition occuring? Anything affecting mixture would also be of interest like a vacuum line being disconnected. A code would really be helpful so keep checking for that. Please let me know if you find something interesting.
