NFS257's '09 URD S/C LT PreRunner Build

O2's will throw a code of they are the cause. Was your computer relocated?

 

Even with a Valium line off it should run. I've disconnected a bunch of mine trying to find a leak and test the evap switching valve while I was hunting down issues with my supercharger. It will idle weird, but still run. I'd guess it's a wire more than likely for the ecu

 

Problem happen after huge overhaul on truck, start checking grounds, loose wires, fuel system since I'm Assuming they had that apart ..

 

It will run without o2s, it should at least sputter with a mad problem

 

He's been helping me. We are both at a loss.

Computer and wiring are all stock.

I have an external fuel filter and when cranked fuel pumps out. I have traced all the grounds I can find and all are clean and tight. I'm sure it's a wire somewhere just haven't found it yet.

 

so then maybe fuel rail, injectors, you already checked the MAF and its all good right? scan for codes and see what pops up if anything. just spit ballin here.

 

Check the basics, is it getting spark, is it getting fuel into the cylinder, I know you said the pump is working but maybe not the injectors

 

Have you thought about calling @Speed Freek ( Jason ) ? He is a full on ASE Toyota / Lexus certified tech.

 

He's in the desert for the next week lol

 

Were you able to figure out the issue.

 

Like mentioned...check the immobilizer

Mine went bad a couple years back and would just crank and nothing

Best way is to see if the little blinking light under the radio (by the hazard button) is blinking.
If it's not blinking without the key then that means it's bad..

But if it is, When you put the key into the ignition without turning it it should stop blinking...then it's working.

Hopefully it's something simple.

 

Fuel pump self destructed and bladder got pulled in. Hope the bladder isn't torn or punctured.

 

Any idea what caused it ? Damaged during the build of the new cell ?

 

Just off road jostling. New setup.

 

I will explain my theory shortly.

 

So the fuel system is closed loop with the only bent being in the charcoal canister. It vents back to the engine. The fuel pump sucked the semi solid bladder in on itself until gas gauge wouldn't work. Then it also snapped the fuel pump assembly in half.

So come to find out the bladder is almost inside out and there is no fuel even though I thought there was at least 1/2 a tank.

 

Might want to put a vent on the fuel cell and just plug it when it's time for smog

 

So to summarize...your out of gas well at least your not dicking with having to drop an OE tank etc.

I killed my charcoal canister after we did my truck. When I redid all of the fuel and vent hoses to work around the CO ( short bed probs ) I had to step up and step down sizes from the OE neck to the tank and canister and in the process I missed a hose clamp. Everything was fine for a couple months then one night while filling up I noticed the smell of gas and saw it dripping under the truck...looked in the wheel well and saw the gas leaking out of the lose hose connection at the filler neck. Next thing I knew I had 6 Codes and my canister had been flooded with gas. So, somehow the lack of a seal allowed it to flood ? I heard it was a flaw with pre 08's and the newer canisters have some sort of fail safe to keep that from happening.
