help with a friends ford

[Irish_Alley]

well my buddy at work has a 95 f150 4.9. it has a random problem besides it being a ford. it will start running real rich, and flood the engine. this only happens on random startups. never has it ran fine then at a stop light started to act up. only on startups not sure if its just when its cold or when its hot. it does have eec so when I tested that it came back with at least 10 codes if I dont it right. so I cleared them since I didn’t know what was new or old but I do remember seeing a maf code, just have to wait till next time it acts up. it doesn’t throw a check engine light either. but it might still store a code. it almost seems like the coolant sensor if screwing up or maf, anyone have anything to look for while we wait for a code. also when it starts up and acts up if he lets it warm up 10 min or so then tries to drive it, it still doesn’t want to go. I dont know what would happen if he warmed it up and shut it off then restarted it.

     My parts guy at work has a f150 with similar problems, after taking it in, the shop says the (2)  o2 sensors are acting up, they are not completely bad just sometimes they do weird things, after replacement I do not believe he has had a problem.

I had a Ford Taurus with the same symptoms. The owner said it only did it randomly at first. He waited until it did it all the time to make an appointment with us. The morning he was supposed to bring it in he was 2 plus hours late as thats how long it took him to get it started, and to the shop. Then he parks it right in front of the no parking sign on the bay door and shuts it off. It never started again. we pushed it into the shop. It threw a MAF code, and O2 codes. I replaced the MAF sensor and it solved the problem.

well i know its been a while. but been waiting for the problem to reoccur. so one day it started again this time (info i didnt think had anything to do with this problem) he checked his gas tank for some reason and gas was pouring out the front tank. he had stopped using this front tank cause we thought the pump was bad this was at least a year ago. i mean he un did the cap and gas would just flow out. he thought he wife was filling up the wrong tank cause the front sending unit was saying it was over full and he never puts gas in it. so they siphoned it out, i think they didnt do it right cause they only got 5 gal out. but the problem did stop. the he was in va playing softball and his wife had the truck she calls him up and says the brakes go straight to the floor no brakes. so once he comes back home he tells me and i head over to fix this. had a hole in the line so we had to replace a section. now thats fixed so we take it for a test drive the truck starts bucking. i look at him this is my first time in the truck and ask is it about the screw up he says yes. so i get him to pull over i get out seeing black smoke from the pipes and thinking now. somehow the fuel return line is back feeding to the wrong tank causing nowhere for the fuel to go now so i unscrew the gas cap to the front tank only to have it start pouring out. i tell him to swap tanks so he does im waiting for the truck to start running out of fuel due to the pump not working. and nothing it continues to run granted takes about 30 sec for the black smoke to clear up but it did and ran perfect hes been running on the front tank now for about a week with no problems
