We changed spark plugs & wires on our 1991 GMC & seem to have the order wrong on the distributor cap because truck won't start. need diagram


Here is the firing order diagram for the 5.0 liter (305), 5.7 liter (350) and the 7.4 liter (454) V-8 engines (note position of locking latches/screws between the 3 and 6 and the 1 and 2 terminals on the distributor cap). Let me know if you need the 4.3 liter V-6 engine diagram (hopefully not in a 2500 series truck) or if you require any further assistance.

To bypass the other switches, run a wire from the battery to the starter bendix and if it cranks then the problem is in the wiring or the switches you mention.
