New guy here. Actually new to the Ford world. Came across a good deal on a 92 F150 with the Inline 6 owned by my wife's family. It starts but runs very rough and dies. No way to even get it to move under power. If i keep my foot on the gas, it will stay running, but still rough. I crawled underneath and saw a rusted fuel filter. Hoping that was the case, I changed it. Didn't really help(though the gas I saw coming out of the fuel filter was nasty, so I'm sure it will help in the long run). From what I have been told, it ran great in July/Aug, then started running very rough out of the blue and it has sat since, being started randomly since. In Dec/jan, they put a fuel treatment in it to keep it from freezing. Fuel gauge shows 1/2 Tank. Air filter is OK. Cap and rotor look OK, not terribly old, but I will replace soon anyways.

My uncle is thinking its some bad fuel and to drain the tank.

Any other thoughts?

Thanks for any help offered. If there is a link to information that might help, please put it. I usually try to research stuff before I make a post, but I'm in a time crunch.

 

first thing i would do is eliminate the possibility of bad gas.
if it was last fueled in july/aug. then the viability of the gas is HIGHLY suspect, IMHO. gasoline just doesn't keep like it used to.

as far as troubleshooting these trucks, ford gives us a bit of a leg up by providing a schraeder valve on the fuel rail with which we can easily test fuel pressure (using a gauge ... fuel squirting out when you depress it doesn't constitute a proper test).

also, one can easily pull codes using the self-test connector located on the drivers side fender close to the firewall.

 

it is my daily driver so unless it was bad gas from the station then it is not that.

ok
