Please help me! i have an 88 xj and having problem getting it running. the motor turns over but there is no fire to the plug. also there is plenty of fuel pressure but it seems the injectors arent working. the plugs are brand new. i would think they would be wet from fuel when trying to start it but there not. dont know what to do. all help would be highly appreciated. thanks

 

Unplug your cps and back in again,see if you have power to the icm under the coil. Did you unplug anything?

 

Yep, sounds like CPS. With a bad CPS you won't get fire to the plugs or an Injector fire pulse. You can have good fuel pressure all day long but, without a fuel injector pulse, the fuel never makes it to the cylinder.

 

ok thanks. i actually already replaced the cps. i havent checked to see if there is power going to the icm. i will check it out. thanks!
