I have a the SLE K1500 5.7L/4L60. I replaced the cap and rotor, coil, spark module, and just did complete timing replacement about a year ago. It has good spark and fuel but will not start. Does not sputter or anything. I am at a loss and ready to scrap this thing. Checked all fuses as well. Any ideas or pointers are welcomed. Thanks!

Yep, lets start by checking the engine compression to make sure we are not chasing our tail.

Here is a guide:

Please let us know what happens.

Okay, I apologize, it looks like I am not getting spark at the plugs. New cap and rotor and spark control module, but still no spark at plugs.

Do you get spark from the ignition coil?
