CHEVY TURNS OVER BUT WILL NOT START

1994 Chevrolet Truck

Engine Mechanical problem
1994 Chevy Truck V8 Two Wheel Drive Automatic 165000 miles

Here goes,
Turns over but will not start,
1. Fuel pump works- removed filter temporarily blows gas a plenty (hoping it would catch fire)
2. Replaced rotor, cap, coil, and eventually distributor. Could get to small coil below firing points.
Checked all fuses, swapped 30amp ones after checking with meter.

Stumped from here

Cranks and will not start: Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, If you can hear the fuel pump come On- check the fuel pressure with a fuel pressure tester designed for your fuel system to rule out the fuel filter/fuel pick-up strainer/fuel pump/pressure regulator and also listen to the injector/s are they pulsing or hook up a noid light and see if it flashing, If you don't hear the fuel pump, check the fuel pump fuse and fuel pump relay-Depends on what type ignition system is yours, No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, camshaft and crankshaft position sensors and computer Note: If it doesn't apply to your vehicle disregard it meaning if it doesn't come with one ignore it and continue testing

KISS, after replacing the distributor, I neglected to get both the plugs back on the rear of the disto. I had correctly identified the small coil pick up on the bottom of the timing inductors.

OH well. Looking for the timing specs now
