Well, checked the fuel pressure from the fuel distributor and got 65 psi. Let it sit for 10-15 minutes and it slowly went down to 50 and stayed there. This tells me that the fuel pump and accumulator are working well. Tried to start it today..turns but will not start. I am not getting a spark again. I'm still wondering about that EZL. Usually, an ignition module will work or it won't. Internittent issues with ignition modules are very rare. i did see it a few times with a GM HEI system.
Before I consider replacing this part..which isn't cheap, any suggestions as to what else I may look at?
