Working on a 91 jeep 4l have no spark did roater and cap and still nothing

Where exactly is the "ignition control module" located at on a *1991* Jeep 4.0 ?

MasterPro Ignition - Ignition Control Module Line: MPI | Part # 2-7090 As for position no clue cause I have a 97 and its near the starter.

Never seen one on the *1991* and up year models, 'ALL' of em I've worked on it is an integral part of the PCM .

They don't look like normal ignition control modules normally they are black plastic and have a connection that hooks like spark plug wire. If u copy paste into O'Reilly auto parts you will see a photo. It looks like a metal box with two plugs coming out. They usually ground to the frame.

Yeah, pretty familiar with those .. Up to 1990 year model.
