Hi my name is Kristian and i am from Norway
I have a Jeep Wrangler 97 2.5l Gasoline
When driving home from work it started to act like crazy ,jumping and dropping in rpms until it died. It startde right up but did the same and died. It did so about 4-5 times until it woulden`t start anymore
Previously when driving on the high way it would do the same, die but then start right up, like lack of spark or empty on fuel.
My mechanic has now had it for 6 weeks, told me it was the ECM. I did not belive that because my old was only 6 months old, and the symtomps diden`t add upp. Anyway i swapt it for a "new " one, still no luck.
Her is what i know so far :
No power to coil .
PCM Black connector, when disconected , i get power (5 v) to coil.
When put back in , nothing.
Cav 17 on connector measures likes it`s grounded constant ( mechanic told me ) ?
Switch plate brand new
CPS 5 months old but might be of poor quality
O2 sensors fault codes reported lean mixture so now it gets to much fuel
Any help is much appreciated
