So, I hooked up my brand new HF fuel pressure gauge (thanks for the tip at $19).
Sure enough, starts, runs fine for a minute, starts missing, fuel pressure drops, engine dies as pressure gets under 20lbs. Wait a minute, engine starts back up, repeat cycle. All of a sudden, I see a spray of fuel coming from injector #1. Can't really tell if it is coming from the short hose from fuel rail to injector or the injector seal. I assume that I caused this problem while moving the fuel rail around when hooking up the pressure gauge to the test port. The only way to make it leak is to put everything back, but then there is too much stuff in the way to see where it is leaking. The injectors have been replaced by me in the past, but it has been over 15 years. Should I just bite the bullet and replace all 4? Can I get mine rebuilt (do they replace the hoses?) I found injectors reman'd by Standard Motor Products for $35.79 ea on Rockauto - are these any good, or junk? Thanks |

Pressure dropping after start and then recovering after a few minutes sounds like a fuel delivery issue. Kink in the fuel line or dirty filter/tank sock. Basically the pump is pumping faster than the gas coming in. Turning off the engine allows it to replenish and pump at pressure until it depletes again.
As for injectors, the oem green tops for 2.0s are getting hard to find or long in the tooth. I had a set of 4 that I sent to mr injector and 2 failed. He recommended the Standard Products FJ67 as a direct fit replacement. I have 4 new ones running in my engine now and they run great |
