error 23 even after replacing TPS, traced wiring, good.

[jasonmbeamer]

my 86' ford ranger 2.3 just died while driving down the road. hooked up a code reader and it gave me several errors refering to the TPS. so i replaced it. All the errors went away but one (code 23). And it still wont start, i traced the wiring and determined there was nothing wrong there. ive adjusted the TPS within the slotted screw mounts but still error 23. I'm stuck. can anyone out there help me out PLEASE......

When it dies, does it act like it's out of gas? I'm having the same problem with my 86 2.3. Trying to work on it right now, and if I'm right, it's either a fuel filter or one of the two fuel pumps. Mine sat for a couple years with crap accumulating before I picked it up and I think the whole system's a bit on the goofy side, but I also got code 23 after replacing my tps. Runs like a champ when it wants to though.

This is definetely not a fuel delivery problem. It probably has alot to do with the EEC IV system. You will go crazy changing all of these parts with no resuts but a empty wallet. If you have more than 25,ooo miles on your fuel filter, change it anyway. It is highly unlikey that it is your fuel pumps: (very rare).

it wont even start. but I have always had a problem with fuel delivery. I replaced the fuel filters, replaced 1 of the 2 fuel pumps and it still had problems. but becuase you are getting error 23 and it still somtimes runs i will change the other fuel pump. I had bought it awhile back but never installed it. its the one in the fuel tank. $140 ouch... thanks for your reply. perhaps thats the problem. I'll let you know if this helps.

Since you already bought the other fuel pump; you may as well change it if you have that much ambition. Your truck is 19 years old and it won't hurt. Try one thing first before you do. Have a friend or you crawl under the truck by the fuel tank. One person turns the key to the on position without starting the truck. The other person listens for the fuel pump in the tank for engagement; if you here it make a short whining sound you know it is at least working before going through all of that trouble. Being that the truck is so old you will probably have to cut the straps holding the tank on. Hopefully not. But be prepared to have a new set on hand. I hope you don't have any problems. Good luck...

It actually was a delivery problem. On the in-tank pump, the strainer was almost black, and the connector hose from the pump to the sender was totally shot. It was badly deteriorating with a mammoth sized hole in it and not sending an adequate amount of fuel to the rest of the lines. This was making the pump heat up and then cut out when it hit a certain temperature. Another of Ford's little safety features to avoid tank explosion. When we had the pump out we tested it and it was fine, but for the sake of preventative maintenance I replaced it. Mine only cost $65 at Kragen, and since I changed it, my truck's been running like a raped ape! Now I'm very pleased with it.
