Agian - When and how did it stop running? Were you driving it? Did you go out one morning and it wouldn't start? Did you drive it to the store and come out and it wouldn't start?

Ok, when you put the new Cap on did you make sure the Firing or was correct. In other words, did you replace the cap and rotor first and leave the wires on the old cap and moved one at a time from old to new placing wires on correct tower.

Once fuel pressure is tested turn key off watch fuel pressure for about 2 minutes, pressure should only drop about 1 - 3 psi. If drops more or drops as soon as key is turned off the fuel pressure regulator is bad and will need replacing.

Well if all else checks out then it is a good possibility that the Fuel Injection Assembly or as some mechanics call it the Spider Assembly has gone bad. Check out pic. It is located under the Intake.

Only one other thing comes to mind, and that you did check. Cylinder Compression. Which could indicate a Blown Head Gasket.

Check your Oil - Does it look like Milk Chocolate? If so good indication of blown head gasket.

Check for Oil in Coolant - another good indicator.

Check out link below for how to check compression

Sorry go to get to bed have to work EMS in am. Hope this has helped some anyway.
