94 astro will not start

I have 94 astro, run fine, before putting the front end up on jack stands to replace most of the suspension. It was up for about a week. After taking it off the jack stands, the van will not start. It turns over but will not fire. And suggestions.

If it turns over I'd check for spark with a timing light. If you have spark I'd check the fuel pressure next.

i have a 91 was told its the ignition module, wih no spark

Fuel : Is the fuel pump in the tank ? Do you here it hum when you turn the ignition switch to on ? My 86 does.
Do you have fuel in tank ? Dumb question but.....
Another suggestion: take off the air filter cover and squirt a shot of starting fluid...."I mean just a shot". Crank it over. Does it fire up for a sec ?

Try checking your crankshaft position sensor. It is mounted on the on the front of the engine next to the harmonic balancer on the crankshaft. If you accidently hit it or damaged it in anyway the van will not start REB
