sputter hot start
1996 f150. When hot it acts like its flooding. Will hit on a couple of cylinders and i hold it wide open and will usually pick up 4cyls and i can drive it where within a mile or 2 it clears completly out. Latey it has been losing one cyl till it completely cools off after which it starts just fine. Do i have injectors sticking open with the heat. ? Definately worse in summer. I can usually spray a little ether and get it to clean out at its worse but today that didnt work. If i dont turn it off its fine but sure as i do when its hot and let it set for more than 5min or so rough start or complete flood like today.

I had a fuel pump relay go north in my old Honda and it acted the same way. Pull the computer codes before you do anything else. Self diagnostics are a wonderful thing.

Been doing this for a couple years now progressively getting worse

That's the exact thing that happened to me with leaking injectors, but they would clear up in a few minutes.
If started immediately after a hot shutdown, it was okay.
It would blow black smoke out the exhaust when it was happening. That shows it was leaking gas.
No codes.

Im pretty sure they are leaking down. Sometimes ita so flooded it wont light without ether. Like today.

Let it cool off since 3 oclockand just fired right up perfect jus now.

Does seem to do a little better when i put a qt of atf in tank. I guess its just time for injectors or at the least rob an injector rail at parts yard.

Isnt there a feature on these trucks that disables the fuel pump on a hot start to keep from flooding? Could I retard the timing just a little to help on hot start ? If it runs on ether then dies seems its a problem too. Done it again today. 3 hours later fired up like nothing happened.
