tired to do key on engine off and it told me

p1294 injector high side open bank 2

cleared all codes and retested 2 codes came back p1316 ,p0541

tired to do cylinder contribution test would not retest due to two codes

does anyone have an idea at per what is going one the truck has absolutly no power doesn't sound right almost kind of like some cylinders are not firing when i did a buzz test i heard all injectors firer a few did not sound as loud as others

when you do a buzz test does it do all at once then one bye one ? I counted 9 buzzes

if anyone has any ides of what direction to point me in or if require some more information please ask

 

I suggest you pull the passenger side valve cover and plug the harness back in. Then see if it runs better and try to clear the codes.

Yes, there are 9 buzzes. The first buzz is all 8 injectors hard. Then 8 more buzzes, each with 1 injector hard and the remaining 7 injectors soft.

Edit: See post #6. Bank 2 is Drivers side, which is the valve cover harness to check instead of Passenger Side like I first suggested...(Oops)

 

why would automatically assum the passenger side ?

if i did the 50 cent mode would that had pervented this if it has come unpluged ?

 

One of the codes said high side open on Bank 2 which is the passenger side.

Yes, the $0.50 mod will prevent the harnesses working loose.
Your symptoms indicate a loose harness under the valve cover as a prime suspect. It is free to check so that is why I was suggesting you look there first.

Hope this helps...

 

I agree. Open it up.

Apologies...
My error. Bank 2 is the drivers side on these engines.

I was using AE to trouble shoot an O2 sensor issue on my LT1 and bank 2 on that engine is the right side. I knew I would get myself confused one of these days....

 

Put your head between the speakers to hear this in stereo. This is how the buzz test is supposed to sound.

Thanks Tugly, that helped answer one of the questions in my injector testing thread.

This is going to be fun ........I had to move the truck to day and it ran fine for about 5 min. Then back to what I said was going on

 

Look like it was all most unpluged is there anything I should do since I have it open.

 

50 cent mod. and retorque everything

 

Retorque everything. Spec ?

 

Just wanted to say thank you for the help. Fte crew was right agene

 

Did you get the specs to re torque your under the valve cover stuff? Rocker arms, etc.

 

No never got the specs. But will do next time I'm working on it need to do the up pipes at the end of june
