All right I'm at my wits end with this truck it's a 1995 Ford F3 50 7.3 dually quad cab It's Tabs Dad he run it out of fuel twice then about a month or so it started idling rough and not really want to start in the morning that went on for about a week or so then he was driving it and then it's hard to drive and rough just as rough as it was idling then he drove it like that for about another month and then it he started having it to where it was dying on him occasionally then we were at a stoplight one day and it died on him and took her straight home then we brought it here why I've been working on it First thing we discovered it wouldn't get enough fuel because of the tank selector valve so I tapped on it got it to work for the time being then we went to getting enough fuel pressure to the fuel bowl so we figured it he burn up the pump so we replace the tank fuel selector Valve and the fuel pump and also I took out all the injectors open them bottom part only and cleaned him come to find out one of them had a piece missing and one of them had a broken spring so I fixed it and put them back then we will get fuel to the bowl and all the cylinders were hidden but it just still wouldn't run so I did some more research it some more tinkering and replaced die PR valve and ICP valve because my troubleshooting led me to believe that those may be a problem as well so so far it's got a tank selector valve a brand new fuel pump ICP valve and I PR valve then we were able to scan it somehow or another we figured out that we could scan it so then we got a scanner and scan it it was saying high side was open on the driver side I'll send u the codes So I troubleshoot it that and found the valve cover gasket was bad and we just replaced it back last year this time so what I did was I replace them both and I did a Home reading on the entire system and I have that as well I will send you and I follow that procedure and I ohms it out 3.8 For the whole system and I double checked the IDM and everything to that seems to be OK as of yesterday it ran for about a minute and a half it chugged really bad but it ran There's proper amount of oil and a high-pressure oil pump There is enough oil in the motor there's proper amperage in the batteries proper voltage in the batteries had to replace the starter because I guess us trying to get it to crank over the other day her but a week ago it burned up starter so we replace the starter and I will send you the last thing it showed because now I'm having an issue to get the tester to read it For no longer works on his old vehicles and have no way to scan them so if you know anybody that has an in-depth scanner to do it it's it takes an OBD two that's what it's been updated to because I don't know what else to do we done everything that I could fine as far as troubleshooting and what I can fine as far as the half ass manual so I can get here in there Here is a list of all I have checked or replaced: 1) changed oil and filter, checked oil level. 2) checked fuel bowl for the loose heater - good 3) checked fuel filter, changed it less than 1000 miles ago 4) check glow plugs out of the motor 5) checked all engine compartment fuses 6) checked wiring harness for frayed ends 7) replaced the ECP? (front sensor) 8) checked for oil on the ICP sensor - none 9) replaced several CPS's 10) checked HPOP it's up to spec 11) changed both VC gaskets & checked harness.
