does it have a spark on the plug wires?how much fuel pressure does it have while turning the starter?will it start with starting fluid?
Customer: replied 6 years ago.

Yes it has spark.

60-61lbs while turning the starter. The local auto supply house guy said to use cab cleaner instead of starting fluid because its less harmful to the motor but no it didn't start

ok

i would think you may have a weak coil..these will do this sometimes have a spark and not start also,the rotor or distributer cap on these vortec engines will cause this

...fact is,as long as the engine is in time and it has a spark..it will run on the carb cleaner or starting fluid

I was thrown off by the fact that it had spark. I replaced the all the coil, rotor, and cap. and it started right up. Is there a way to test a coil?

Testing and Inspection

Note Make sure the ignition switch is "OFF".
  1. Disconnect the distributor lead and wiring from the ignition coil.
  2. Connect a suitable ohmmeter as shown in step 1. Use the high scale. The reading should be infinite. If not, replace coil.
  3. Connect ohmmeter as shown in step 2. Use the low scale. The reading should be very low or zero. If not, replace coil.
  4. Connect ohmmeter as shown in step 3. Use the high scale. The meter should not read infinite. If it does, replace coil.
  5. Reconnect the distributor lead and wiring from the ignition coil.
