OK here's the story.
I bought a 96 blazer that needed head gaskets, put everything back together, charged the battery over night, changed the oil, filled the coolant, etc.

new ignition(coil, ICM, Cap, rotor, wires) and I'm getting a weak spark from the wires , tested spark from coil=strong,
tested spark from plug wires=weak and almost non-existent

Any ideas?

 

Get a/c delco cap and rotor nothing else is good on our blazers

 

It turned out that the pick up coil was bad too

 

Pickup coil? Are you meaning the crank sensor?

 

Yah, the same part was listed under both the pick-up coil and crank sensor.
Now it won't start with the Mass Airflow Sensor plugged in and there is a knock that has turned out to be a bent rod, probably from the pressure of the coolant that was in the cylinder on top of the piston....uggghh


When I bought it, it seemed like a good deal, $1,000 with only 154,000 miles on it and all it needed was a head gasket. Well, I tear it down and both intake manifold gaskets leaked and there was coolant in the #5 and #6 cylinders. Now about $250 later after gaskets of all sorts, new ignition parts oil, coolant, plugs and now new push rods I'm starting to think not such a good deal.


Just frustrated, thanks for listening.

 

Your 96 doesn't have a pick up coil, what part did you replace, (where is it located on the engine)?

 

on the back of the distributer, if not a pick-up coil then probably the crank position sensor

 

That would be the cam sensor. The crank sensor is located at the front bottom of the engine.

 

Yup, camshaft position sensor is in the distributor, and it can not cause a no start condition, (the engine will start and run with the sensor disconnected). After replacing the sensor, camshaft retard must be checked/adjusted using a capable scan tool.
