Has anyone ever heard of having spark at the beginning of cranking then it would go away after a few seconds? Is my module going? Or am i just seeing things. It won't start and I'm running out of thoughts of what it could be.

 

Check power and ground at the coil.

 

Did it voltage is good, ground is good. I replaced the module just to be sure still the same. I'm starting to think the ecm is bad. Any suggestions?

 

Did you check the pick up coil inside the distributor? I have come across a similar problem and found that the pick up coil was falling apart and not doing its job fully.

 

yes I checked it. It looked in good condition and I checked it per the manual It read 975 ohms or something I don't remember exactly. So its within specs. This is just racking my brain because I do have spark, Its timed right, there is compression, and I even changed the carb to rule that out and unless that one is bad too I don't know where else to go. Right now I have the timing cover off and I wanted to check to see if it jumped a tooth or something but its right on, the chain is a little loose so I'm going to change it but I don't think that's the problem. I'm thinking maybe the knock sensor is bad retarding the timing when I crank it so enough it won't start or the computer may be bad. That's what's next unless someone can point me somewhere else.
