SOURCE: Changing a cap and rotor on 2001 Chevy Astro

pull off the center console inside the van to expose the engine. the distributor will be right in front of you. remove 2 screws from the cap, and make sure you get the wires on in the exact order you remove them, or else it wont start. rotor is underneath cap, and i believe the coil is right there on the cap.

SOURCE: 1998 chevy pickup won't start. Replaced fuel pump

How many miles are on the engine? Has the timing chain ever been replaced, if it hasn't there is a possibility that the timing chain has jumped a tooth on the cam gear which throws off the ignition timing and will keep it from starting but you will still have spark and fuel.

Check the plug wire from the ignition coil to the distributor cap.
If you haven't already, replace the distributor cap and rotor.
The GM Vortec's have issues with moisture getting inside the cap and rotor and causing problems.

1989 gmc 2500 305 engine back fire's on excelleration. Replaced Rotor and Cap. Also oxigen censer. Checked plugs, Wire's.


Backfire on acceleration could be caused by a worn lobe on the camshaft especially on a small block Chevy engine. You have to remove the valve covers and check the lift of each push rod. Sometimes it's quite obvious but sometimes it requires close inspection and even measuring the lift.

96 chevy tahoe won't start?


Mine did this with a cap and rotor. I changed it six months prior, but ended up having a faulty cap from Jegs which caused it to backfire. I had crank, spark, fuel, but the cap was crossfiring and wouldn't run.

This cost me a new flexplate, two starters, still a cap and rotor just due to the backfires.
