Need Help

I pulled out of my street this morning and my truck would run really rough when I went more than 1/8 throttle. It idles fine and the truck was warmed up. I am throwing codes that injectors 1-4 check circuit. When it is at a stand still and you rev it it backfires around 2000 rpm. This happens with the stock tune and the xtreame street tune. Is this a failing FCIM? Please help!

click on the troubleshooting a no start condition in my signature and it gives you a test procedure for the FICM. Yes when you throw multipe injector codes it has been the FICM failing more often than not.

I just tested it and with the key in the on position it reads 48.6 but with the motor running it is only at 26. Does this mean the FCIM is bad?

Yep, it is bad... Try the resoldering before you plunk down the coin on a new one.
