Hi i have a 2001 chevy silverado with a 4.8 engine my problem is that i am getting current to the driver side of the injectors but all four injectors on the passenger side are not. what can it be?

Thank you (tennisshoes) for your quick response. I did check my fuse under the hood it did checked out good. I will check the injectors because all four cylinders (2,4,6,8) are not firing, My thought was that it was not firing because the main wire that sends electricity has no power witch is the pink wire on the harness, I will upload a photo of the harness so that you can see what i am talking about. Again thank you for responding,

try a new cam sensor and crank sensor

Did you ever find out what was the problem my 2003 chevy Silverado 4.8 has the same issue I was thinking it’s maybe a bad wire or ground ?

I have had a big problem with my fuse block under hood, try un hooking and re hooking with the 2 leavers that release fuse block. It with seperate up s little, just enough to re connect. I do that everytime my truck goes into limp mode or reduced power sorry and it fixes it. Or another is re programming the key. No joke it works. Also make sure you have no other car keys on your key chain. Other key codes mess with security will make it not work.

I went through this w my 04 5.3 Yukon was a weak fuel pump and throttle plate tps was shit replaced both and zero problems since less purge solenoid not purging and cats tossing o2 codes (unrelated) the symptoms were ran good at high rpm but would run decent at idle then after about 30- 50 seconds idle would start chopping, killing the passenger side, would pop and poot at low speed take off.
