86 f150 inline 6 cyl starting problems
Hello,
I have a 86 f150 inline 6, it was running fine and then I parked, loaded the truck and it died. I noticed that the egr valve was leaking a small amount of fuel. It was the original one from 86, I replaced the egr valve. It will crank strong but will not start. I noticed that the carb seemed flooded. I felt inside the carb and it was wet with fuel. I waited a few hours to let it dry out, same result. Not sure what to do from here, sensor, fuel shut off??? here is a couple pictures of the carb, let me know what you think, thanks again......

Have You checked for fuel delivery at the Carb ? (IE: fuel pump issue) ... (spark) ... an issue I had, my engine was running and I took it out and rebuilt. Back together and no start ... found the plug sensor that is on the side of the distributor (sorry cant remember the exact name ) had quit working. Replaced and it started right up ... just a couple thoughts

The Choke Air Flap is closed or hung shut. no air gets in, floods, wont start. hold open choke with a short tool screwdriver, try to start with throttle wide open to get fresh air into manifold, if it starts feather throttle to get it to run, and warm up.
choke may be the issue. choke should be fully open when engine is at operation temp. fuel level in carb may be trash on needle & seat. float in carb may be heavy from sitting in fuel due to age of carb.
A place to start on getting it fired up. Hope this is a fix??
good luck

My theory; There is dirt in the carb, and it has hung the float needle open flooding the carb. Take the plastic handle of a screwdriver and peck on the top of the carb. Get someone to hold the gas pedal to the floor and crank it while you peck on top of the carb with the screwdriver handle. Holding the pedal to the floor should force the choke open.

I am thinking the plugs got fouled from fuel during the no start. Sometimes driving on the high way can clear them but if not you will have to change them.
