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!

1991 4.3L GMC Jimmy S-15 will not start. Turns over, but does not start. Replace spark plugs and wires, ignition coil, module checked good. The plugs are gettin fire but not sending it to the motor?


You need 3 things.
Compression
Good hot blue spark to all plugs.
Good gasoline and proper fuel pressure. 13-13.5 lbs on your TBI
If you have all 3 then move on to injector pulse to both injectors.

Keep me posted and recheck your spark plug wire to make sure they are not crossed. firing order 1-2-3-4-5-6 cylinder # passenger side 1-3-5 front to back. cylinder # drivers side 2-4-6 front to back
distributor #1 is located at the 7 o"clock and rotates clock wise so next distributor post on the right working clock wise is #2. Good luck and hope this helps.

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.
