I have checked the following , 5v reference on all engine management sensors , CPS , CPM, MAS , IAC , O2 heated ect all check out and if I unplug one at a time the gauges never move , I ran self Diag on the cluster by holding trip odometer and turning key on , cluster is fine , I have 2.5 v on pin 3 /11 on obd plug and that is to the bus of the system for ADS ?

How can I test my PCM ?

I have ordered one for 199.00 online with warranty for 1 year

I jumped the fuel pump 87/30 and it works

I jumped ADS relay and 87/30 and it picks the injectors as it should ?


This a Canadian model 4.0 L

I bought it for 450.00 this way no start , no gauges , no spark , no fuel

Please help a new / old jeep buddie ! I know how to look just need to know where !

Thank you guys
