SOURCE: 1991 4.3L GMC Jimmy S-15 will not start. Turns

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.

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!
