I like his thinking ..!

I have to take it to a county drop off . I put a bottle of heat in with the tank of gas and will for a while . I little off at idle but throttle responsive and cruises the freeway fine . Codes cleared and haven't came back " yet " ...

I am a regular customer they know they'll get it back 10 fold . Hopefully it was caught before too many people filled up . But what a pain ...!

I appreciate you guys trying to help and your input Thank You ..!

I disconnected the fuel line at the fuel rail , inserted 8' of 5/16" hose into the braided fuel line opening fit perfect , grabbed 5 home depot pails and lids , dropped my spare tire opened the fuel pump control mode plug mounted to the frame , jumped the fuel pump and it pumped out 20+ gal's in 10mins . My '11 doesn't have a fuel pump relay or fuse under the hood . Didn't drop the tank , loft the box or go thru the filler tube .

It would fire and wanted to start. The fuel rail would regenerate pressure and lots of spark . I grabbed a fuel pressure tester and it was 60 PSI when cranking . Air , gas , spark . It just started acting up minutes after i topped off the tank ( $78 / 22 gal's ) so out of curiosity i ran some from the pressure gauge relief into the jar and sure as ****** ..... milk/gas ..... the gas station closed off the 89 Octane pumps and happily reimbursed me . It turns out someone backed into the fueling truck hose when he was refilling the station tanks and broke something and thats when they think the fuel got contaminated .

The jar came out of the truck , the glass on the right is year old gas for the snow blower from last year . The new gas ( 20 gals ) was what i topped off with and had to drain . Truck is back to normal .

It was 23 gallons of bad gas

I am leaning towards a crank / cam sensor . But all the codes were MAF and TPS

Before i had the issue it had rough idle and boggy start but would clear up once i got going from a stop . So the fuel pump was keeping up at higher RPM's .

Yeah i got a backfire with starting fluid earlier today . It seems like the the MAF or TPS weren't telling the computer to give fuel . I agree the codes don't mean ya have to replace parts but they are factory 260K miles on it . And autozone is 5 mins away . I have a Hypertech programmer and cleared the codes unhooked the battery for the night and will try it again in the morning . I will also try cleaning the intake ( butterfly ) at the TPS and check pressure in the fuel rail again .

I agree and am getting my Azzz handed to me with this one . If my fuel rail is full it should run 10-20 sec's and then run out of gas . Thats not what happens . The fuel rail valve shoots fuel 1-2" high consistently so the pressure is in the rail and should be weaker if the pump Is failing or not keeping up .

I searched each code and replaced each part .

The day before 50 deg's ran fine the next day 12 deg's let it warm up , filled the tank Nd noticed a miss and super sluggish and stop lights and signs but would clear out and run fine over 1000 RPM's driving .

Codes were P068 P0223 P2119 P0122 i've replaced each part and the ignition switch

I tried cycling the key 3-4 times to build fuel pressure but didn't mame a difference . The fuel shoots 1-2" in the air each time i check the fuel rail for pressure / gas

At 1st it poppped right off , ran 2-3 sec's and died . Now it fires but won't catch . It did want to run with Ether but i didn't want to stay running .

My Silverado ( 5.3 ) fires but won't catch and run . I replaced the MAF , The TPS , the ignition switch . I checked No.1 and No.7 plugs their not fouled . The fuel rail has gas i checked 3 different times and pressure seems consistent .
