1990 Jeep Wagoneer XJ / 4.0
Recently purchased a 90 Wagoneer that had been neglected by the PO. Drove home ok (~3hr drive) known issues were no AC, brakes/suspension (not dealt with yet),and botched master window switch.
So far this weekend I've done:
**Entire replacement of heater hose/rad/ac system and all lines
- is holding vacuum nicely and no leaks, etc.
**Entire ground refresh w/ beefier grounds, all terminals replaced as needed and cleaned
- thought this was initial problem, re-checked and all testing fine and doesn't seem to be the issue
**New cap/rotor
**New Bosch plugs
** New plug wires
**Valve cover gasket
- 2hrs of scraping the old cork off - clearly hadn't been changed in at least 100k
** New thermostat / water outlet
**New Ignition coil
- testing within spec and fine on multimeter
- ICM was very crusty and was cleaned, is also getting power
**New starter relay
- same as coil
**Vacuum line replacement all around, with exception of replacement cannister
There's more but it really doesn't matter much to the issue at hand.
CPS is testing within spec, tested in AC
Coil, ICM, everything it seems is getting power. Fuel is not the issue, o2 senors are fine, fuel ballast bypassed.
Only thing that should be done, but isn't (first RENIX but not my first rodeo) is I forgot to put the coolant sensor in the new rad, but it is connected and getting power - just don't feel like dumping coolant right now.
Jeep cranks but it just won't start. Next step on my list is going through the pin out on the ECU.
Lastly, there is one "extra" connector on the pass side harness that cannot be figured out for the life of me. 2 pin, blueish connector, red/black wire.
...any suggestions?
