Well, it's acting up again, but it will remain as is for the time being as I have plenty else to do.
OK that friggin oil pressure sender...
I yanked the one from the 3FE and put it on the 2H. Recall, the gauge is the 3FE's. Well, I turned the vehicle over (after many tries) and the gauge shot up beyond the hash marks to its mechanical limit. Even 30 seconds after I shut her down, the needle was still pegged at the top and then slowly came down.
So...2H motor, 3FE oil sender and 3FE gauge...not right.
2H motor with 2H oil sender and 3FE gauge maxed out about 1/3 the way up the gauge.
Presumably the 2H motor gets much higher oil pressures than the 3FE.
Lastly, I see the coolant temp sender in the Haynes (no, I do not have the FSM. Yes I know, shut up), and clearly on the 2H (staring up at you, right next to the radiator, perched up nice and easy to get to, but for the life of me, I can't find it on the 3FE. It is in the water pump?
