1990 geo tracker fuel pump not working.
#17
congrats !
Bad coil for , 1ohm ? failed or clogged.
easy fix. fuel pressure good, noid good, no squirt, is in fact, a bad injector.

can be, one injector is shorted, OHM IT CAREFULLY , never use any injector ever, not ohm checked. (open injector coils dont hurt ECU)
if you do, you will risk burning up the injector drivers in the PCM (fixed many , too many ).
the other is a shorted injector feed wires to ECU, can burn up the ECU, same way. easy./

one guy, put a 7amp fuse on the ECM red wire side , for injector, to current limit , this for future shorts. (5 years running_)


use a meter that can measure 2 ohms accurately, one that has 0.0 ohms with leads shorted, (mine has button, that is marked zero'd) this cancels the lead errors
allowing 1.0 ohms to be seen accurately
the 0.8 ohms is max low. less is bad injector, as you know coils can short , open or can short 1/2 way, and must not be used,

i hope she holds good,!
