Guest jjohart Posted March 4, 2004 Share Posted March 4, 2004 My 280ZXT mechanic called me and said the "as new" injectors Z Barn sold me must be varnished, as they aren't working, even though they hooked up a fuel gauge, checked the fuel rail and firing computer...absolutely NOTHING!!! I'm stuck with a dead car in their possession, and the guy at Z Barn is slow to reply. Is there anything my unassuming mechanic can do to fix these, other than letting the gasoline "sit" and perhaps "work its way down" so they might eventually break the varnish free?!!? IF I have to send these back, can anyone tell me if Merkur/SVO/Ford brown top injectors are plug and play? Is there a FAQ or page anywhere which clearly spells out such a set-up proceedure? Other than a Bosch High pressure Fuel Pump (which I have, have been saving!), what else will I need to increase performance, or at least have the Merkurs work out of the bag!?! Thanks John- 83 ZXT 5 speed Quote Link to comment Share on other sites More sharing options...
SleeperZ Posted March 4, 2004 Share Posted March 4, 2004 I realize it is risky, but I may have had the same issue when I bought brand new turbo injectors... Mine would not fire, and it seemed as though the pintles were stuck in the seats. Using a toothpick, I gently pushed up on the pintles and they snapped off the seats, and started working. I ran the injectors 2 years without any further issues. Quote Link to comment Share on other sites More sharing options...
Tim240z Posted March 4, 2004 Share Posted March 4, 2004 When I first tried to fire my LT1 when I finally got all teh wiring etc finished (it had been sitting for a couple of years by this point, between me and the wrecked Z28), it would not run on all 8 cylinders (running on 5 or so). What I did was (with the car running) tap on the injectors with the handle of a screwdriver. Worked like a charm, and I haven't had a problem since.

Guest jjohart Posted March 4, 2004 Share Posted March 4, 2004 Hey y'all, a bit of Techron, gasoline and time was enough to convince the injectors to move, first only a couple, but gradually into all 6! Thanks for the help! Seems like injector changeovers can be a bit hair raising, even though it ain't that many labor hours in it. In closing, if I ever go to higher flow injectors, I'm probably better off paying Jim Wolf than buying off E bay--or maybe not!?!

TEST the injectors before installing them! Quote Link to comment Share on other sites More sharing options...
Guest jjohart Posted March 6, 2004 Share Posted March 6, 2004 HOW does one "test" injectors...who is the sort of person in the phone book (outside of CA!) who has a "bench" to flow test...what does that mean, anyway?
