hey, new guy here. i'm trying to figure out a problem that has been plaguing my plowtruck- '96 2500 with a 360. when i hit the key if it doesnt fire immediately it floods out. bad. if i let it sit or 20 minutes and try again it starts and runs perfect until it gets parked again. its not a daily driver but when it snows i need it right now. any help would be awesome. thanks

 

Not sure what you mean when you say it "floods out". I don't associate that with fuel-injected engines. What are the symptoms that you attribute to flooding? Is there a strong smell of gasoline, or are other things going on?

I had a problem with my '94 318 a few weeks ago that might remotely be called "flooding". The distributor cap had carbon build-up inside it that was causing arcing and a no-start situation. I fixed the cap, but by then the plugs were soaked with gas and wouldn't fire. New plugs, vroom. Maybe I could have dried them out, but at $1.77 each I just replaced them.

Rule out all of the simple things first; plugs, cap, rotor, wires. Check for spark if you know how, post again if you don't.

 

"floods out"? elaborate

 

floods out like strong gas smell, backfired once and blew the muffler apart.

 

Possible coolant temp sensor. Or, a bad connection there.

Worn plugs?

You are using champions, aren't you.

 

floods out as in an injector(s) leaking into cylinders?
or might it be out of time?

 

dont think its the timing cuz once it starts it runs great. could be an injector. is there a good way to check?

 

what would a bad coolant temp sensor do to it?
