Hello,

Recap: injector is clicking (listened via stick), fuel is there at the fuel rail-fuel hose fitting, no fuel at FPR vacuum hose, CPS is ok, spark is there (runs with starting fluid - thanks Aleekat!), RSR is functioning (12v at injector plug)..

Have you RULED OUT debris blocking the injector's mouth (the tiny filter on its top)?

If debris is there you'll HAVE to replace your main fuel filter too (beside the main fuel pump underneath the car).

Even if you manage to get the fuel pressure gauge (screw connected to the Schrader valve) it just reads fuel pressure within the rails. But this high pressure won't do you good if debris is blocking fuel going thru the injector.

It is IMPORTANT to visualise the tiny filter. If it is torn then surely debris had stuck in the injector. You'll need professional help to clear this or replace the injectors.

Remember you did mention some filter debris i.e torn filter material was there when replacing the pump.

Hope this helps,
Amarin.
