If you changed your plugs, etc. and know that you are getting a good spark then it's really only 2 other things to check. The compression in that cylinder and the fuel. Check fuel pressure with gauge hooked up to Schrader valve on fuel line next to your distributor ( it has a black threaded cap on it). If pressure is good then you have either a dirty or clogged fuel injector or the injector quit working. Let me know what you find. Anytime you get a misfire in a particular cylinder, you should always check for spark, fuel and compression.

Cranks fine but wont start. i can smell fuel. seems like its not firing.


I would check for a spark first, but you can pull of the distributor cap and check if the rotor is still turning. If it is not turning, you may have a broken timing chain. If it is turning and there is no spark, it is probably bad spark plug wires, spark plugs, distributor cap, rotor, camshaft position sensor, or crankshaft position sensor.

My jimmy seems to be missing, but only when it rains, I would like some help. Mary


depending on what motor is in your Jimmy and if it still has a distributor, that is where i would start. moisture will get in side the distributor and cause a miss fire. This is a common problem with GM trucks that still have distributors instead of coil packs. Try haveing some one replace the cap and rotor or silicone around the cap and see if it seals.

I need a spark plug wire diagram for a 1985 gmc jimmy 350 engine


Most all Chev or GMC v8 engines use the firing order of 1-8-4-3-6-5-7-2. You have to find where #1 is on the distributor cap which is usually closest to #1 cylinder then looking toward the back of the engine go clock-wise to install the rest. Don't get too close to the headers. Plastic melts!

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.

The destributor cap was loose, engine was running ruff, replaced cap, tuck running fine. After 100 miles it is running ruff again and check engine light is on. I found a hose around the destrutor cap,...


When's the last time you replaced the spark plug wires? Try that for you mis-fire. As for the vacuum hose, there should be a routing diagram somewhere on the hood or engine compartment somewhere. Trace it out and find where it should go. Oh BTW, bad spark plug wires can ruin a distributor cap.

Spark after i changed distributor cap but wont start


sounds like you haven't indexed the rotor correctly or the cap isn't seated correctly.  Did you replace the plug wires correctly?  Dis you bump the position of the distributor?
