I haven't been worried about my injectors because my A/F ratio was good, but I just checked my IDC tonight and with just the bolt-ons in my signature sitting at 86%...I'm scared to think of what it was on the nitrous. (couldn't test because my bottle is empty, but I don't think I want to risk it til I get new injectors.)

So..especially you dry shot guys, stock 28.8# aren't enough..hah

I'll be buying some 42s soon..

86% IDC with those mods probably means that your fuel-pump is giving up the ghost.

I know your pain though. I'm at 98% IDC with my mods, and it shouldn't, meaning that the pump is giving out.

With your mods, I would think your injectors would be good. I agree with TA-Swede, you may be looking at a pump issue.

Hes right, there is no way you should be at that IDC with just those mods. Wouldn't hurt to get the 42's but the pump will be needed soon

Do these fuel pumps normally go out at 50k miles?


Maybe I should have posted this in the fueling section

Some do, some don't. Mine's at 71K, so..

There's many cases where the factory pump gives up early in life or can't keep up to any additional HP over factory.

remember that GM pumps have a nice failure rate when people run their tanks down below 1/4 of a tank..
The pumps really need to be submerged... Even though they still go..
I have seen alot of pumps go from keeping low fuel tank....

Once I kept my tanks above 1/2 at most times... I have not lost any more pumps, as to when we ran our tanks in 3 different gm vehicles to almost empty.. I have replaced alot of in tank pumps.
