DirtyDeeds Posted April 30, 2017 Share Posted April 30, 2017 do the fuel injectors have to be plugged up in a certain order?? i put injectors in a few months ago and i just pulled them to flush them after i put my new tank in. the first time went good and it ran perfect for a week till the new ones got clogged from the gunk in the old tank, this time however the injector harness cam apart on me while i was pulling them and when i put them back i can't tell if they went back where they came from. it seems to be running a little worse also, even tho the injectors are perfectly clean now. i noticed the the hot wire on the injector connectors are kind of color coded, grn/blk, yel/blk, orng/blk, grn/blk again, yel/blk again, and orng/blk. any ideas??

Ωhm Posted April 30, 2017 Share Posted April 30, 2017 Looking at the 88 electrical manual your color codes don't line up. Your going to need to pin (0 ohm) each injector wire from the ECU or C101 to determine which injector is which. This assumes 88 wiring is same as 87.

DirtyDeeds Posted April 30, 2017 Author Share Posted April 30, 2017 new info, I'm out there looking right now and 3 of the 6 injector plugs have the label AMP stamped on the side, does that have any thing to do with winch cylinder they should be mated with?
