98 Chevy Astro

rc,

Last time my ole '91 Astro did that it was the ignition module inside the distributor. If it's got a carb like mine, one easy way to check it would be to remove the dog house and top of the air cleaner and pour a SMALL amount of gas directly in the carb... if it lights, then it's a fuel issue, if not, probably the ignition module.

Good Luck

You need to verify:

1) Fuel delivery 2) Spark delivery 3) Ignition timing (if #2 is ok) 4) Engine timing/compression

It's one of those 4. Figure out which then we can take it from there!
