Maybe you have the injectors reversed,or the crank position sensorsor mixed up with the temp.sensor(I did that).

I did check the crank sensor and temp but not the injectors

I'm taking it that the blaze ran before the valve adjustment. Was the valve clearances ok or did you have to adjust them?

it ran started and ran perfectly before and I had Colby at CD racing do it. He said it needed 4 shims in it.

From what see if your plugged in correctly the first step here is a compresion test.

I have not seen valves needing adjustment much regardless of mileage so when all 4 needed to be reshimmed thats the first red flag. If the valves were shimmed then cams were removed .To do so cam timing can be set wrong hence a compresion check will tell you everything you need to know. Compression lower than 50psi will for sure cause a no start /backfire/fouled plug. Was this engine updated ?
