    Hello Lincoln Family,

    I have a 1967 Linc. Sedan that’s currently having issues with over heating and hard to start up after turning off from a short ride. After waiting for the car to cool down it starts up with no problem. There are no lights on the dash signaling. I have replaced the starter and put a wrap on the starter. In addition changed the alternator but not luck. I am at a loss on what it could be at this point. It’s been going on for a couple of years. Do anyone have any suggestions on what I should try to fix the issue.



    When you say hard to start do you mean it turns over slowly? Slow to fire off?  It could be several things as these cars are rather finicky. Make sure all your power and ground cables are in good shape, that you’ve got the proper 3 port fuel pump with return line and pump heat shield (provided you’ve still got the 462 MEL engine) or an electric fuel pump upgrade.

    Often the correct 3 port fuel pump is the issue.  Parts stores don’t have the correct one, it’s a two port and a cobbled together return or no return feed at all.  Finding a rebuilt correct OEM pump solves the hot fuel boil off/vapor lock problem these cars are plagued with.

    Also make sure the fan clutch is in good shape, the radiator is flowing well, the radiator shroud is intact, and the timing is set properly.

    Good luck!!

    Hello Jeremy,

    Thanks! Yes, you are correct that turns over slowly. I am going to check out the 3 port fuel pump and see if that fixes the issues. I had it tuned up and assuming it was done correctly he timing should be okay. I will also make sure it was timed properly.

    Thanks for the help! Will let you know how it turns out.
