2008 Sequoia not running after fueling up

I've read through a lot of threads already and nothing has fixed my problem, short of starting to spend hundreds of dollars. Filled up my Sequoia 5.7L and backed it into the garage and it died. Has not been right since. That was 4 days ago. Thought it might have been bad gas, so dropped the fuel tank and siphoned it out. Put about 5 gallons of good gas back in. It would just crank and not start. Only way to get it to run was squirting fuel down the throttle body, but once that fuel was gone it died. Checked all the fuses, vacuum lines, cleaned and tightened gas cap. Disconnected the battery and it finally started, but idles rough and sounds like it's missing and smoking white from the exhaust. Went for a drive about a mile down the road it spit, sputtered and backfired then babied it home. Then the vsc, skid, and engine light came on, as well as the 4lo light was blinking. Disconnected the battery and lights went out, let idle for a while still sounded rough and then lights came back on. Don't have a code reader and not sure it can be driven far enough to get to one. Any thoughts?

 

Plugged up fuel filter maybe

 

Bad gas. Mixed gasoline. Usually, water in the gasoline. I would drained all of the gas immediately, and not try to get it running through your vehicle. Once the bad gasoline has been fully drained, fill up at a different gas station with premium gasoline and add a bottle or two of gasoline treatment and injector cleaner.

Good luck.

 

What these guys said. Happened to a friend of mine. Had to empty the tank, clean the pump (ran good gas through, I think ) and replace the fuel filter. Modern trucks don't like cheap fuel.

 

Did the fuel you siphoned out smell like diesel?

 

What year Sequoia and how many miles?

Agree with changing the filter.

Going in a different direction, how does the oil look? Antifreeze in the oil?

 

FYI, bluetooth ODBII dongles are $20-$25. Torque app works on Android or iOS. Great thing to have.

I have one on my Tundra, and my Honda daily driver. When the truck squealed once when I turned it on, I knew immediately it was the alternator without even opening the hood as Torque was showing me the voltage.

When I flushed the coolant in my Honda a few weeks back, I monitored coolant temp driving to work and back for a few days to make sure there were no air bubbles left because I had a hellacious time getting it to burp air (tiny 4 banger generates hardly any heat).

You can also view and clear codes with it.

 

Test the fuel pressure to make sure you're actually getting the proper fuel flow to the rail. If the pressure is low there is the pump to consider and also a fuel pump control module, either one could be the culprit.

 

Nope no diesel smell.

 

115,000, Oil looked good.

 

I definitely need to look into getting one of these!

 

Thanks for all the ideas. Ran into a local mechanic and he said he has a couple vehicles that come in every week with similar issues. He suggested checking the spark plugs. Figured they were due up to be changed anyway, so went ahead and got 8. Left the battery cables off all night and then changed the plugs. Two were fouled for sure. Started it up, no lights came on. Went for a drive and seems to be running fine.
