1994 GMC Safari my van won't start.

Engine Mechanical problem
1994 GMC Safari 6 cyl Two Wheel Drive Automatic 172, 00 miles

I went to start my safari van and nothing. I could hear the fuel pump run for a few seconds and it would stop. I changed the relay and the filter but it still won't start.

Do you
have the same problem?

Pick your symptoms

Cranks but no start condition:

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 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, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. 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, cam and crank sensors and computer Note: If it doesn't apply disregard it.

If both fuel and spark is present-check the valve and ignition timing, this will lead you to problems
with compression and valves opening and closing at the wrong time/broken or jumped timing

No crank at all/nothing/nada when key is engage to starting position

Could be a blown fusible link, the starter, starter relay, clutch switch/park and neutral switch/transmission position switch and ignition switch assuming the battery and connections are good. Note:If it doesn't apply disregard.
