Item 6 covers how to test for spark. First, test all under hood and under dash fuses with a test light or multimeter and check for codes. Typically in these situations, the problem ends up being with the coil pack or Crankshaft Position Sensor.

Thank you Tx. I sprayed the crnakshaft position sensor with break cleaner, did the 30 minute key on and off, put it back together and it fired up.

Hi Tx, guess I'm playing parts changer. It appears that the head gasket, may be the cause, I plan to use the sealer by nano technology. So far I can't tell what the real problem was and if it still exists, I changed: crankshaft position sensor, water temp sensor, thermostat, ignition module, the 3 coils, fuel pump fuel filter. Inspecting the oil fill cap had some traces of the pretty color of anti freeze. Hope the nano adds to the cure,I'll try to keep you posted. Have a nice day.

05-26-10 The ignition switch may have been the no start culprit. I had to replace it, to apply the nano treatment. The next step is the block cylinder leak check. I'll use 300 miles as a break in.
