Hello folks.
I’m a newbie here and have know for doing things bass akwards. I should have came directly here first, but either way here we are.
03 250 5.4. A lot of what I’m about to list seems to not be related to each other but maybe someone can shed some light. For context had a minor accident in which their insurance salvaged my truck. I’ve made all repairs but still have to pass an inspection that will fail you even if you have gig in your headlights.
most vehicles on the road won’t pass this pass or fail test at $600.the abs light has always been on but will fail. Then I got a code 0460 and another I can’t remember close to this. Saying my gas gauge not working but it was. The instrument panel was in and out but gas level worked. I started getting cylinder codes and everything pointed towards the fuel pump.
dropped tank, replaced pump and fps.
started up and then coolant going into the spark plugs. Manifold is fine replaced the gaskets, plugs the coil packs. White exhaust steam pouring out the tail pipe.
ran head gasket sealer through and seams to have stopped the bleeding.
however, it’s still running poorly, misses a lot with codes 0171, 0174 and 0460.
i have installed and triple checked and smoked all vacuum lines.
new fuel filter and pcv valve. Cleaned egr. The fuel pressure is at 40 start and drops to 35.
my 02 sensors seem to be working in the scanner in normal flux. But I am replacing today along with fps solenoid and all new injectors.
lastly, my fuel trims were at stftb1 and b2 at 4.7 and Ltft b1b2 both at 24%.
now those numbers have swapped and the short terms are at 29% and long terms are at 10%.
Im just chasing ghosts and my salvage title is 7 months over due I can really used your guys help
