    I had a pretty good day today.
    1st I got the generator put back together and it is running well enough.
    2nd I pulled the injectors out and verified the passenger side is clicking with a 9v battery applied.
    Driver side injector does nothing.
    I pulled it apart and hit it with some air.
    Now the injector is stuck closed. I looked at the first video and you can see the injector is stuck open. I'll call AFI Monday and see what they say. Hopefully they have some snake oil to prescribe or send a replacement I've treated this stuff like a box of eggs until it was on he engine where it can't be kept from the cold. It should work.

    I made a new throttle linkage

    Then I put it all back together. It started and ran well enough to get out of the way and clean the oil off the floor but wouldn't idle long without the 2nd fuel injector.

    Last I worked on the tank access.
    This will have a new pickup and return tube from the top which allows for pulling the line, pump, or filter without draining the tank. Just unhook it at the high point on top of the tank.

    All in all I'm happy with the parts. Hopefully the injector is not a big deal to replace. Everything is very clean and of good quality.

    I noticed I need to replace the q-jet parts in the to-go box with an extra relay, o2 sensor, map sensor, fuel filter, 10amp blade fuse, paper clip, 9v battery, multimeter, and I want to print some troubleshooting pages that apply to each sensor.
    I feel like this is much easier for me to work on than the quadrajet. There isn't much you can't check with a multimeter and a paperclip.

    Not exactly exciting video, but documenting where I am now is a critical task if I am to know if I am winning or loosing later on. I would like the passenger side temps to be a little more even.

    I'm happy. I think it's 2deg advanced on timing. It's really hard to look at the timing mark with the alternator where it is.
    I really couldn't do all of this myself without a lot more time and it would have cost the same imho.


    To do:
    Button up the tank and lines.
    Mount PCM
    Recover the drivers seat
    Edge protection for all the holes in the firewall.
    General tidying up of the wires.
    Bolt down the hardtop.
    Road test with and without trailer.
    Pull the driveshaft.
    Take a vacation.
    Do some easier fire roads
    Then I've got a more serious trail ride (other parties are 4speed flatties with lockers)

    My alternator is in the same spot and it really makes it difficult. I found that if I look down the drivers side of the alternator. My timing will not be set right. I must look down behind it.
