any suggestions. my 98 jeep grand cherokee laredo 4.0 auto quit. it cranks but no spark. the crank, cam, oxy sensors seem to check ok if i'm doing it right. i've got a wrecked 98 that ran until i pulled the motor and i used it's pcm to no avail. grounds clean and tight. no engine code when doing the on/off three times. the asd relay energizes, but the voltage isn't getting to the dash or distributor. my haines and chilton only have very limited schematics that don't help follow wiring. anybody got wiring diagram for this vehicle or proper test for sensors if i'm doing them wrong, or other suggestions thanks
i unplugged the distributor but none of the symptoms changed. no gauges still, and there is about 4.5v to the sensors but no gauges still. will see how to check pick-up coil. thanks
