Hey guys I just put a new TBI Sensor on today, I do know my fuel pump is bad, It still works but when I turn the truck off then re start it, it will take a couple seconds to regain pressure in the lines. I don't know if this is why my truck is not accelerating well and my big lose of power? But if yuo have any idea why please let me know. It is very sluggish from a complete stop to 60.

I took a video from 0-60 mph, this is completely matted to the floor from a dead stop I will have the video on here tomorrow some time, It is taking awhile to upload Im not sure why. If you text me I can send you the video also. 330-614-3028

I really need to find out why my engine is running this way. Gas is killing me. Thank you and please text me if you need to see the video.

heres the video

umm. fuel pump is bad but still runs enough fuel to get it moving to some degree. What psi Is it running at. Cat cloggin up at all. Plenum (as this is adressed in every post it seems) fixed yet? videos kinda crappy but i get the point. thats probablly not how it always ran.

 

Maybe the combo of dark and the gauges was throwing me off but I didn't really see anything out of the ordinary.

Also you got some fairly big rubber on your truck, what gear's are you running in the rear?

 

Is your t case in 4wd? The transmission shop put the lines on backwards so 4wd was 2wd so the axles weren't spinning but the t case was and made it very slow

 

My truck might be slower than that lol

 

My cat is hollowed out, I have no idea about the psi I have from the fuel pump how do I check that? And I do have o2 sensor codes coming up

 

Also, how can I check my plenum before I go rip it apart

 

You check fuel pressure with a fuel pressure gauge connected to the fuel rail on the intake manifold. You can probably rent one at your friendly neighborhood auto parts store.

Oxygen sensor codes? There goes fuel economy and power right down the toilet. On top of low fuel pressure? You're lucky to hit 60MPH on the same day you mash the pedal down.

 

Okay thanks.

 

Take off your throttle body, get a little dental mirror and a flash light, look for "pools" of oil, check all around, including the corner's. If it's all nasty and dirty that's a good sign you need a plenum fix. Haven't you already fixed the gasket but not the plate? Or is that someone else I'm thinking of?

Does your truck use excess amount's of oil?
