I know it's not a B Body. But having starting issues. Sometimes it will crank right over and sometimes will not get any spark from coil. 360cid TBI. Replaced ignition switch, Fuseable links. Any ideas?

To clarify, sometimes it's getting spark and sometimes it's not but it's cranking right over fine all the time?

Just a thought. First thing I'd listen for is the fuel pump running. Open the gas cap and listen. Can you hear the pump run when the ignition is turned to on (not cranking)?
My dad had an intermittent start problem on a van. Replaced 3 fuel pumps. Pumps were failing due to the positive feed wire corroding inside.

Yes. I can be driving and it just shuts off. It will crank and crank but no start. Then ten minutes laterm it fires off with no problem

Can smell fuel from TBI

I would check if this has the oil pressure switch inline with fuel or spark circuit.

Not sure that alone cuts it as I think the pump needs to provide pressure or the automatic shutdown relay kills the ignition.

Checked all ground. Does outside temperature play into it?

ASD Relay kills the pump
