96 cranks but wont start
I am trying to help my dad get his blazer going again. It will crank and sputter every once and awhile but won't start. I tried some starting fluid and it still wouldn't start. We changed the coil on Sunday and it cranked for longer than usual but it did start. Now dad is calling me a day later and it won't start again. I put it on my scanner. No trouble codes and it had 170rpm when cranking so the crank sensor is working. Is there anything else that would keep me from getting spark?

Sounds to me like you need to do a feul pressure test if their is not at least 55 psi at key on this is defintly his problem. Had a simmuliar problem with one not to long ago

That was the first thing I did, 61psi. It has no spark

no spark at the plugs or coil or both? if it's not at the plugs check the coil if none at the coil try a new coil pack and you might be in luck.

coil pack, ign module, distributor pickup.....possibly/probably one of those three items. TEST TEST TEST.
