Suspect the crankshaft/camshaft sensor may be bad which controls timing of both spark and injector firing. The check engine light should be on--rent a scanner, read any codes and pursue to repairs. Hope you installed the new distributor exactly as the old one.

These trucks like the blazers are notorious for the fuel pumps going out in them, as well. So listen for the fuel pump to engage when you turn the key over. This isn't the only way to check it but its one of the easiest.

89 gmc jimmy 5.7L it gets spark from coil to distributer but not from distributer to motor. Spark plugs and wires are brand new, module is fine, cap and rotor is fine.


if im correct in saying this, i think there is a small cylindrical looking piece with one wire comming out from the front in the distributer under the distributer cap next to the points this is could a condenser you could try changing this for a new one all so check the gape your points make if to small you will get no spark as well if to big

HAVE A 1996 GMC JIMMY 4.3 NUMBER 1 PLUG IS NOT GETTING ANY FIRE TO IT .I CHANGED PLUGS ,PLUG WIRES , DISTRIBUTER CAP AND ROTOR BUTTON SO WHAT COULD BE MY PROBLEM?


it does not mean new parts are alway good. subtitive a known good wire and check for spark at the wire, if there is spark then check the plug.
if there is no spark then go back to your cap.

Number 2 spark plug


Are you sure it's the spark plug that's faulty or the ignition wire?? How old are plugs and wires?
If you don't know if it's your spark plug not firing or your ignition wire you could move spark plug to number 1 then check your code reader.
Or you could do an ohms continuity test on your number 2 ignition wire to verify that there is no break in the wire. Common problem to check for. If wires and plugs are old and high mileage maybe should change all including cap and rotor on distributor. Fresh wires plugs cap and rotor always improve mileage and performance.
Good luck, sorry can't help with tranny.
