Hi,
I have a ford ranger '90 2.9L EFI.
I'm suspecting a fuel pressure regulator (FPR) problem so I made a pressure test. The result is bugging me!
With the key to ON, on the first fuel pump activation I have a reading of 0 (Zero) PSI. To get the needed 40 PSI I had to activate the pump 5 times. And that's not all! If I don't touch anything, the pressure start going down until it reach zero.
Then I started the engine and got a constant reading of about 78 PSI.
With these results, should I consider that my FPR is faulty or a vacuum problem?
