Need a little fuel issue help

[Rolnaz]

I think I may have a or multiple Fuel injectors leaking.
If I use a regular FP guage its holds at 52lbs, if I use my after markey Electronic FP Guage it starts and 52 and drops slowly to 15. I have not taken it on the road yet with teh guage fully installed. I bought this guage just to trobuleshoot what might be a fuel pressure issue at idle and take off.

Is there an easy way to test each injector, or with almost 300k on them should i just replace them all? if its replacement, then should I just stick to stock or can I get a different one that may cost a little less and work with a Factory tune.

car details:
MSD Coil, and Cap, Brand New Opti with Lifdetime Garuntee, Taylor OTC wires, BBK shorties, cool air intake, new Fuel pump (3rd 1 in 2 years), new Pressure regulator, new TPS.


any help on the recommended parts, or someway to check my injectors, or other things to check.

Just replace them with new stock 19lb(I think) injectors. Your not pushing enough power to go higher.

There is a way to test them but I can't really explain it accurately by writing. Basically you take a spare electrical connector and 9v battery, hook it up to fire the injector. This is with the injector out of the car. That will tell you if it's firing.

I need to stay out of GM tech. :ROFL:

actually you might be able to test them. Take the whole fuel rail off the intake and pressurize the inlet with air. Use soapy water on the injectors to see which is leaking, make sure you have the clips still on them so they don't blow out.

Could also be the check ball in the fuel take (I had that problem), could also be a leaking fuel pressure regulator.

You can also pressurize each individual injector. You don't need a signal to find out of they leak since they are leaking in "key off" position when they are not hot (energized).

Stock LT's should be 24s if I remember right. But with that kind of mileage I would consider replacement Just my $.02

no idea if they have ever been replaced ... so replacement it is, just wasn't sure if there was a mild performance gain from some others that might even be cheaper.

whats this check ball thing, does it mean a fuel tank replacemnet? I am also going to buy another fuel cap since it has been a fee years and almost 80K miles.

thanks for the tips, we did a fuel leak down with the off the intake and still connected to the car, no leaks. Guess i will just look at replaceing them since the 2010 Cam dosen't look like its gonna happen for me. so i will be keeping this 1 a while longer.

oh heres a 2010 link if you havn't seen it ...

These should be o.k. and half the price of the OEM brand, unless I go reman with a core.

Accel Performance; Fuel Injector

I can get the 24 or 26 for 279 on summit, maybe I should go that way.

Check ball is in the fuel pump. You'd have to replace the pump. Usually if that's the case you'd lose all the pressure eventually and not just a partial leakdown.

Third pump in little over a year, so i doubt that. but anythings possible.

I think you will be fine with those injectors.

I would also replace/rebuild the regulator at the same time just to be sure you have everything in proper working order.

regultor replaced less than 3 months ago, mabe 6k miles on it.
