injectors

[demon55]

I am having an injector issue with my 7.3 L. Left cylinder bank not firing in 2-4-6-8 , and weak on right cylinder bank. So I am trying to find out what would cause just one side to go completely out. I also put in a new fuel filter. Any help would be apreciated.

im just a rookie but see if all the injector lines on that side of the engine come together at some place cause that could be a good spot for a clog.....or get someone to hook a computer up to it and see if it is throwing any codes

I did an injector test, that is how I found out the left bank was out. I guess what I'm trying to find out is why just one side would go out just like that, and if anyone came across this problem. Thanks for your help my97blowsblacks.

It knocks real loud and won't move in drive at all with pedal to floor. RPMs stay low.

If you tested the injectors you should also be able to check your hpop pressure That would be a good place to start

hi i had a problem some what like yours first the wiring harnes is probly ok because the problem affects all cylinders i would look in two main areas your main fuel pressure from tank should be around 40 psi and check for volume also the eletric pump is located in frame rail under drivers cab the next area i would check is the high pressure oil pump it is located frount center under the fuel filter housing assembly should be around 600 psi at idle and around 3000 psi at 3500 rpm

just curious what test you ran to know which bank isnt firing ,injector buzz test or cylinder contribution test , that would lead me in a better direction to tell you what the problem is
