It has fuel pressure, compression, and timing is new and is correct, but it has intermittent spark, one every four or five revolutions new crankshaft sensor, cams sensors work fine hook up a computer on a auto mechanic shop, they said is a internal mechanic problem. I am running out options.
Do you

Thank you for your input. The security light goes away when key is turned to on position. And the intermittent pulse is on the coils and the injectors.

Thank you for the tip, but I tried all of that and more. I just find out the injectors also have intermittent signal. It may be the IEPM? Fuse box. I just want to make sure before I spend the money.

Is there any trouble codes? It could be the crankshaft sensor going out they had problems with that car.

If the shop says it's an internal problem then ask what they meant or it may be a ring on crank is loose or something that is a fluke.
