    Stalling when hot, many codes....

    Hi, back again.

    After fixing stumble problems its still not good.

    Problems with my 1985 cfi colony park.

    It stalled again. After a half hour drive it sat for 15 minutes. Than after a start i put it in gear and it dies. I could only return home by constantly reving the engine. The engine speed saves me from stranding on the highway. After about 10 minutes it return to normal driving.

    I just installed a brand new correct distributor (motorcraft), also a new tfi. Reinstalled the egr, but still with a block off under the cooler. I also installed a brand new motorcraft tps, 0,94 volt closed throttle
    I checked alot of connectors, but nothing found. A cleaned the ground of the eec.
    I reset the eec and checked for codes afterwards non found. Than i testdrove it for 10 minutes and checked for codes again.
    21, 41, 34, 32, 77, 51, 54, 61, 55, 63

    The act act egr tps sensors are new. All the contacts are thoughroughly cleaned and inspected.

    55???

    All the code related sensors use sig rtn from the same pin...?

    Any help is appreciated.

    55 probably means a wiring fault between the key switch and the ECM, or maybe your ECM has shat itself. Considering all of the codes its giving are sensors with a common connection as you mentioned, there is the distinct possibility the ECM is the problem. I would probably suggest pulling the ECM connector off and checking for water inside first tho. I had wierd problems with mine once and it turned out to be water in the plug.

      I will agree, sounds like a wiring problem.

      first I would check your ignition switch, they are notorious for going bad. then I would check/replace the ECM relay. also double check and clean all the grounds for the harness and ECM. verify your battery terminals and all the wires connected to them are clean and tight. ECM's rarely die, so that would be the last thing I suspect.

        I have taken out the EEC and looked inside. It seems to be a remanufactured unit. It looks good. For my Mustang I had problems with my ECU. The condensors were leaking on the pcb and destroyed it. But this unit was very clean and didn't have that problem.
        Some water was found at the connector.

        When checking the relais of the ECU and the fuel pump, the one for the fuel pump completely died. Perhaps this was the problem. It were the 25 year old original relais.

        I testdrove it again and no problems showed up, no stored codes after the testdrive.

        Fngers crossed but not to have my wife stranded with 3 kids, I ordered all items which can also cause this problem, since I can't measure it out. So in go 2 new relais, a ignition switch and a remanufactured ECU (they were on sale).

        Thanks from the Netherlands,

          Did you put new grease behind the new TFI module? They will cook without it.

            Crusty relay connectors can explain it. I've seen a couple with plugs that were melted or with bare and corroded wiring.

              The grease mentioned here is NOT di-electric grease. It is thermal paste, like the kind you put between a CPU and a heat sink inside a computer. If you use di-electric grease, the TFI module will overheat and fail prematurely.

                The paste that came with the tfi is used. I always use this paste.

                I have a heatsink for mounting a tfi on a more cooler place lying around. I intended it to use in my mustang, but I think I will use it in the merc.

                  That's the problem. The last time I got a TFI, it came with di-electric grease instead of thermal paste, because parts manufacturers are dumb.

                    yea, the little tube of thermal paste is like 20 bucks, but well worth it. but, relocating the TFI can be the smartest mod for reliability i think.

                      the last TFI I got came with thermal paste (and had BS in the paperwork about using the included paste or it would void the warranty).

                        20 bucks for thermal paste? Where do you guys shop? Computer stores have that stuff for like 4 bucks a tube.

                            Again troubles. Again 55 key power. I'm waiting on the ignition switch to arive. Sometimes it takes 4 days to arrive in the Holland, sometimes 3 weeks. It is now almost a week.

                              Installed all the parts but still a problem with the fuel pump relais. I installed the new eec and everything's fine. Reinstalled the old eec problems again. Eec is the problem....
