24valve white smoke
Ok I have hard start, whit smoke comes out not much, won't start with lift pump plug in.
After I um plug pump it starts missing little. Plug back in lift pump then I rev it up and will break up on top end never going under 10psi on lift pump and blows whit smoke when it breaks up what could be whrong thanks |
VP44, have you checked it for codes?
|
Haven't checked codes the service engine light not on also sometimes start up fine run then the oil light pressure goes 0 and lift pump off. And strarts runin crappy and break up top end and white smokes I took a jumper wire and plugged in lift pump and turns back on. does the injection pump also have a power source that would turn off?
|
check it for codes anyway. the lights dont always work.
|
Yea I think you VP44 took a Crap, how much PSI is the Lift pump pushin at Idle?
|
I'll check codes and let u know. I have idle 16 psi.
|
Ok so I checked fuel pressure and still 16 but when disconnect pump goes down 0 fast I have check valve on the pick upside I think plunger in injector punp bad and getting air in lines If I put another check valve at end of return lie do your think that it wont leek back.thanks for help.
Also I tried to scan com and no communication to scanner? |
check your fuses sounds like you dont have any power at the data port.
and i still think your pump is bad, just because the psi go's to 0 dosnt mean there is air in the line, you just unplugged the pump there is no more pressure the fuel is just sitting there |
if scanner won't connect check fuses, i can't remember which fuse it is, but I'm sure someone on here will... just because you have fuel pressure doesn't mean the vp can't go out. instead of adding another return check valve replace the one on the vp.
|
even changing the OFV will be pointless if it has a p0215 code or any other pump code, since the codes have still not been checked
