fueling issuses after build

[dommel01]

OK so my brother just had his truck built with an s472, dieselmdr.dual rulers, an 100% nozzles, it will idle fine, when you put it in gear the ROMs will drop pretty low, if you accelerate, now I'm talking to like 5mph it will just flood with fuel, bog out an go no where, an bellow smoke as if you blew a boot, then when in gear will ideal low, an then rifle hi when in park or neutral, has innovatives single tune, anyone have any.ideas as to what this could be?

sounds like a bad injector to me.....but Im far from an expert. Maybe someone more experienced will chime in.

You have a scanner or anything to hook to it?

Its at hasslers right now, hell figure it out for sure but I'm just trying to speed the process up a little, the I ejectors were good before the build

Still having issues guys, it has frp at start up, when you go to go, it drops to zero, the frp sensor voltage checked out, anyone have any ideas, wanna get this truck back on the road soon

Pumps didn't get switched up did they? The front pump is reverse flowed.

I was thinking that randy, but I'd sure hope tommy knows that you would have to use the front pump on the front, I told him too

Did you buy the pump with the kit or separate?

 

[dommel01]

It was taken off one truck an out onto the other

I would check like the others had said about the way the gear is on the front pump. It needed to be flipped over before getting installed into the truck so that it does reverse the flow.

Also if you are not familiar how to do this, there are many youtube.com videos that show how to do this.

Ya I would def check to see if the pump got reversed.
