Starts Runs 5 min then dies and only runs rpugh and poorly after
Hi My 1996 Ford F150 Extended XLT dual tank automatic runs great - starts easy but then after about 5 minutes runs like garbage.
1 - changed out both the fuel pumps and sending units with new - non Chinese made units --
2- Rebuilt Distributor with new Electronic Module
3- New ECU
4- New Blue top O battery
5-plenty of frustration
No one seems to be able to figure out this problem. We thought it was the pumps [ only one was working anyway ] - Changed them out for new - not rebuilt -- changed the ECM - Computer - had to take it back - it is a rebuilt model but did seem to work?

1 - Why? What exactly was wrong with the originals? What's the brand, PN, & source of the replacement parts? Did they pass the same tests the originals failed? What is the fuel pressure from each tank with the engine running well, and again when running badly?
2 - You rebuilt it personally? What exactly was wrong with the original? What's the brand, PN, & source of the replacement part? Did it pass the same tests the original failed?
3 - Why? What exactly was wrong with the original? What's the brand, PN, & source of the replacement part? Did it pass the same tests the original failed?
4 - Why? What exactly was wrong with the original? What's the brand, PN, & source of the replacement part? Did it pass the same tests the original failed? What do the terminals look like? Are they clean & tight? Are they bolted to the cables, crimped, or soldered?
What exactly do you mean by "seemed to work"? How long has this symptom been present? Put all the truck's details into your signature so we can review them with each reply. Click this & read the caption:

1 - Why? What exactly was wrong with the originals? - The fuel pumps were what was thought to be the issue -- so both replaced and they were bad - also many people don't replace the sending units so I did to be sure that part of the project was complete.
What's the brand, I don't have that in front of me - but could get it over the next few days - i got it from Advance Auto
PN, Same as above
& source of the replacement parts? Advance Auto on the Computer
Did they pass the same tests the originals failed? There was nothing to test anything with except for the running of the trk
What is the fuel pressure from each tank with the engine running well, -----------------I don't have those tools available but a Ford Certified [ 15 years mechanic ] mechanic is working on it and again when running badly? See the above
2 - You rebuilt it personally? The Computer is from Advance Auto
the dist. from Ebay - with a very high success rate.
What exactly was wrong with the original? The post was loose inside the dist
What's the brand, N/A
PN, & source of the replacement part? N/A
Did it pass the same tests the original failed? What test ? That's about it for now

Being as you have OBD2 take a look at live data see if intake temp and coolant temp look correct. Could also look at timing advance. Some basic easy checks that could cause your problem.
