Check time it takes for pressure to bleed down after shutting off too.

 

BIG BIG Development.

About 20 minutes ago, I took the battery back out to the truck and hooked it up (It was drained from excessive starting attempts). I had left the hood open for about 2 hours, so the sun could get any residual dampness out of there (The fog, mist, and dampness has cleared up as of this morning). I go to start it, and it starts, after I floor the gas pedal. I take my foot off the gas pedal and it dies. I leave it for 2 or 3 minutes and try again. This time, no gas pedal needed, and it idles fine. I let it sit there for about 5 minutes and warm up. Then I take it for a short drive; about 2 miles. It runs normal for the most part on the trip there; then I go to turn around, and as I'm keeping it still while I wait for a car to pass, the whole truck is vibrating. I go and have to give it some gas, and then big problems. It doesn't stop. I end up going 50+ MPH down a 30 MPH road avoiding cars and pedestrians, and have to turn the engine off to get it to stop. Putting it in neutral just made the engine run incredibly fast. I tried starting it again, and in park it does the same thing (I immediately shut it off again). I assume from this that I have some type of fuel regulation problem. Am I correct in this assumption? Thanks for all your help, both in past posts and in posts yet to come. THanks!

 

Really aught to consider replacing those Toyota floor mats! Manage to hold onto to F/P gauge through all that? We were assuming it was a fuel delivery problem before you took it on Mr. Toad's wild ride! Usually you want to fix something before a test drive. I hope we don't loose you to Darwinian theory before we get this fixed!<JOKE-<

 

Unintended Acceleration..... Wonder if any of the 8th or 9th generation F150's are covered under Toyota's Recall.....

A strange issue has gotten even stranger.. this thread is like a car wreck, I can't stop watching!!

 

I see what you mean... However, since the problem seemed only at the time to be starting it, I wanted to see if that was indeed the only problem. Since I've now found out that it developed WOT, I'm looking for reasons that this could have happened. At one point we removed the lower air hose to squirt some ether in there... Could it be that the hose simply wasn't tight enough after I put it back on and tightened it? that might sound redundant; it's the only way I thought to phrase it. THanks!

 

Did the pedal remain on the floor? or return, but still haul *ss? Are you going to do the F/P check (Bleed down time too)or just take it for more test drives?
