Hi People, I have a 97 tahoe 4x4 with a 350 vortec. last winter i left it outside for four month in sub zero temps while I headed south to enjoy some sunshine. When I parked it it ran nearly perfect but when I came back I tried to start it and it turned over and over and over just fine but no start. towed it in and had the following replaced,
Plugs/wires
distributer/ rotar
all injectors
MAF
all Oxygen sensors
EGR
and some stuff I cant remember,
The truck runs but barely,idles rough, 4mpg, check engine light on at start then blinks when i start driving and the exhaust smells strongly of gas.
The fuel pump/pressure tested out ok. Phewww. just about done. So any ideas people? i've dumped $900 into this thing to make it barely drivable.
Thanks in advance

 

Did you drop the gas tank, and drain/clean it? Did you put any fuel stabilizer in before you left it?

 

No didn't do any of those things, I've been able to drive it since then so I've went through a couple tanks of gas since then so I don't think there's anything wrong with the tank or fuel...

 

what engine codes are u getting, you can google them up online to see what is going on.

 

That, and I'd just suggest disconnect the battery, for a few minutes, then hook it back up

 

Try a new fuel filter

 

I took it to my local auto parts store and did a code check..I dont know if it was the wrong obd or what but it pulled 9 codes!
p0300
0102
0113
0134
0135
0175
1406
0700
1100
This cant be right can it? or is something else causing all these codes?

 

fuel pressure regulator or poppet leaking inside the manifold?how long does it hold the fuel pressure?
