Title: power or ground?
Post by: pioneer4x4 on September 14, 2009, 01:59:23 PM

hello i was wondering if anyone could tell me if the two wires on the renix tbi fuel injector connector are power and ground? its an 86 xj 2.5 tbi. i checked one and it had power and the other didn't have continuity to ground? just wondering if its supposed to be ground or if its pulsated power? thanks in advance.

i think that is answered here: http://jeepgarage.free.fr/OWN/fuel%20injection%20system%20tbi.pdf ... if not it should be in another pdf at that site.. i would look it up but i don't have the time right now.

The ground circuit is pulsed to ground by the engine computer
