dboisen Posted July 26, 2014 Share Posted July 26, 2014 I have a 1988 comanche 4.0 6 cyl it cranks but has no spark. I installed a new coil, distributor, and a cps. Still no luck. Any ideas on what to try next? Link to comment Share on other sites More sharing options...
thejim42 Posted July 26, 2014 Share Posted July 26, 2014 ICM under the coil. First check your connections. Thats what it was in my 88 4.0 Link to comment Share on other sites More sharing options...
cruiser54 Posted July 26, 2014 Share Posted July 26, 2014 Very minimum test the CPS, post 7. ICM contacts, post 4. If I had an 88 I would also do 1 through 5 and maybe 27.
