I have and 89 k5 blazer 350 tbi. I am getting fuel but no spark. So far I have replaced the cap and rotor, ignition coil, starter, battery cables(positive and negative) and fixed some horrible splices that the previous owner made. Any ideas what I should do next? I was thinking maybe a bad ground but don't know where to start looking.

 

Ignition module inside the distributor? See if theres power going to the distributor. If there is then thats most likely the case

 

By ignition module do you mean the coil? if you do it is separate from the cap and rotor and I have not tested if it is getting power or not becuase I don't have a second set of hands until Saturday. My friend was saying maybe the pickup in the distributor does this sound likely?

 

do a search or three, you'll find lots of things to check!

power to dist / ing module / computer? fuses all good?

 

My bet would be on the ESC (electronic spark control).
