p1179 code

So I think this is finally the code to accompany my huge loss of power on road where I am loosing speed going uphill on pavement

TPS is displaying proper

I have tried several MAF all display the same

Checked for vacuum leaks

Hoping it is just the fuel pump taking a crap since I installed a used sender and pump like 6 months to a year ago due to my old sender shorting the TPS voltage

At this point truck is drivable but wants to die in startup with IACV trying to compensate then it runs so...

Guess when I return home will need to check fuel pressure and go from there

Just when I thought this thing was all fixed

At least fuel pumps are cheap and easy to change.
I just put a $100 RN pump/sender in mine last weekend, it took a half hours tops.

Pump and sender for 1998 is $$$$ Abel type like $500?

But sender can be rebuilt with cheap pump from auto zone, I did that on the last one and saved the pump when I chucked the bad sender, so I should just need a new sock and fuel filter

I may change it just because

I am home, 32 psi at fuel rail, sat for over a week when I tried starting it kept starting and dying finally kept running


MAF at idle is .08 g/s seems low is that the correct reading?

Put on an actual fuel test gauge, 28 psi, pinch the return 100 psi and runs great

She is starving for fuel pressure, replaced pump, sock, fuel filter today, no change, ordered a new fuel pressure reg. No idea what else to do

If I unplug current regulator, jumps to 35 psi

With the vacuum disconnected from the regulator the fuel pressure does not jump up when the throttles open.
I might try mine like that to see if it makes any driveability changes. Mine runes at 25psi and jumps to 30-35psi when the throttle opens.

when was the last time you changed the plugs/wires? did you check the o2's?

O2 are done, ntk and functioning proper on data stream, new magnacore in spring and ngk type r plugs, I can see by the fuel pressure test gauge there is not enough fuel pressure

I have 28 need around 35 idle, starving for fuel

get a pump from randy and swap it see if it does anything. if it doesnt send it back to him.

i think it's a different pump from the RRC or else i would say go grab the one that was in my RRC that Ryan drove to the dump

Did pump, sock, filter, squeeze return line pressure goes up engine runs good same as old pump all connections are good

Pressure regulator will be here tommorow, already torn down

Installed the new regulator and Volvo injectors seems to run fine now so guess it is fixed only time will tell

volvo injectors... enlighten me. i heard of people using ford injectors.

Volvo ford injectors got them off 2 joy Volvo actually hard to find this part number injector 0280155746
