When ever I go to start the blazer either in the morning or when (blazer) is hot it doesn't start up on the first shot.

The blazer has a new: distributor, cap & rotor, plugs, wires, starter, Coil(from ebay), and the control module next to the coil (forgot the name of it) and installing that module I did put thermal past on it.

I cannot figure out why it is doing this, I'm leaning towards the coil from ebay.

But this has been happening even before I had or installed all the new parts... so I am at a loss....

Thank You in advance

Jim
