So my 1998 Chevy Express van he's cranking but not turning over. I recently replaced fuel pump fuel filter fuel relay and it was running great. Now it is back 2 cranking but not turning over. There is fuel pressure and the pump is working. And it has compression . What would my next move be? Logically. Spark plugs? Ignition coil? Any advice would be so appreciated. I possess average mechanical skill and I am hundreds of miles from home. But I do have access to any part or tool I need. Help

haven't ruled out fuel injector.

Did you try spraying starter fluid into the intake?

Take the doghouse off, Pull a rear plug wire, check for spark.

If you remove the distributor cap use great care in removing the bolts, the base of it is plastic (thanks again GM) and the bolt holes break easily. This means replacing the distributor, although you could probably get by with a longer bolt fed through a nut with a washer depending on how much of the ear is left.

In reading up on these there's a ton of things that can cause no start. Even I found on mine the coolant temp sensor went bad and it would not start when warm because the computer believed it was -68'F and adjusted the mixture and timing accordingly. I found that with a scan tool checking live data.
