SOURCE: replacing fuel injector on jeep 2.5

Disconnect your Battery.
Remove your air intake and filter housing all the way to the throttle body. Then use a shop rag and release te pressure in the fuel system by the valve on the fuel rail. use the rag to absorb the fuel as it sprays out the fuel rail.
then you unsrew the 2 bolts holing the rail in place.
Then you pry the rail away from the manifold with a flat head.
being careful not to loose any of your injector seals.
when done clean both your injector seats and the rail seats.
use some assembly lube or shop grease to lubricate all of your injector seals upper and lower seals.
remount all parts as you dismounted.
reconnect your battery cylce the ignition key 4-5 times before starting the egine, and check for leaks. if there is no leak then go ahed and start your engine.

Well it sounds like you've started to do your "due diligence", but there are several things left out. Your problem could be many things. Something as minor as a vacuum hose left off, loose, or in the wrong place. And just because you changed the plugs and wires, don't mean you fixed your problem. Open your hood at night and see if you have any sparks "dancing" around. Another way to check this is to open your hood and spray a soapy water solution on your plug wires and look for sparks jumping around. If so replace your wires. You didn't mention what type of wires and plugs you used. I would reccommend NKG platnum plugs and a Bosch wire. I know this from experience,(the hard way teacher). It could even be the gas you are burning. I've owned a lot of Vettes, and I am the kind of guy who believes they should be driven. If not it's like having a beatiful wife and never taking her to bed.I know a lot of people who only drive them "once in awhile". Sitting in thier garage can cause many fuel problems, condensation, sludge in the carb, or filters etc. This can all lead to the problem you are describing.
Low speed miss- usually plugs
High speed miss- usually wires or valves
intermitten miss, fuel or electrical.
I hope I gave you some places to look to find your problem.

The 1989 corvette does not have the LT1 engine, it is a L-98 TPI. The proper rail fuel pressure with the pump running is around 42-44 PSI.

I'd be looking for a few things there. First, make sure that the temperature sender is working. If not, the computer thinks the engine is always cold so it sends more fuel even though it's not needed. Next, make sure that there aren't any exhaust leaks ahead of the O2 sensor. That will cause the sensor to think that the actual mixture is lean, again asking for more fuel. Also check that the O2 sensor is good. Out of range can do the same thing. There are other more complicated causes but those are the most common.

Got an '87 firebird that has been pieced together, looks like 5.7L T.P.I. engine. How can I identify what motor it is for sure? thanks


Look at the fuel injector cover if its fuel injected on top most say it there, it will say 2.8L or 5.7L if it is a v6 (6 spark plug wires) chances are its a 2.8 if it has V8 (8 spark plug wires) more likely to be a 5.7. Check your ECM if its what came with that motor if it is the original GM part the number on it should be 1227165 if it is it should be 5.0 or 5.7 more likely the 5.7.

Injectors on right bank not firing on 1987 corvette its not the fuses dont think its the ECU because i changed that and it did the same thing


Injectors not firing generally the ECU, or the wiring from the ECU to the injectors.

If the wiring is hard to trace, try an auto electric shop to chase the wires for you.

What is the ideal operating fuel pressure for an 89 Corvette w/ LT-1 TPI


The 5.0L injector is sized to deliver approximately 4.05 milligrams of fuel with a 2.5 millisecond pulse or 18.13 lbs per hr at approximately 36 PSI. The 5.7L injector is sized to deliver approximately 4.83 milligrams of fuel with a 2.5 millisecond pulse or 23.92 lbs per hr at approximately 43.5 PSI. This information is typical for all manufacturers and flow rates will vary slightly even between identicle injectors.
Good luck and hope this helps.
