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.

Check for a bad distributor cap and or rotor..........a bad cap and or rotor can caues firing (cross fire)across the terminals and introduce spark to the wrong cylinders at the wrong time.......
hope this helps.....good luck!

try the oil pressure switch, that was a common problem on Gm trucks when I used to work on them, the oils switch was bad and woulden't allow it to start and the ones I worked on were on the back of the distributor.
SOURCE: 96 gmc safari engine turns over but wont start,
buy a can of starting fluid, spray into intake hose, see if engine starts, possible fuel pump prob.

not starting or turning over indicates towards multiple possibilities. It can
be issue with battery or weak battery. But if battery checks out ok, then it
can be starter issue or faulty alternator or problem with low fuel pressure or
no spark at spark plugs due to dirty spark plugs or faulty ignition
coil or injectors getting cracked or dirty and needs to be cleaned.
To
confirm the problem, the basic troubleshooting is required.
