A few things. "cranking" is she starter turning the engine before it fires. If you suspect flooded you hold the petal on the floor. This will tell the puter to cut of injection pulse and allow max air. (flooded doesn't mean you need new plugs)
Maybe something got bumped changing the VC gasket? MAP wires on the TB? Codes?
Man, sounds like a pain,
. Also like mentioned, you can indeed start a new thread.
ok i just changed my cps,coil ond ecu. I had the ecu already but fig since i was changing the coil and cps for no spark i would go ahead and change the ecu also. the jeep starts but it takes a min to fire and runs rough after it does. before the cps went bad it fired fast and ran smooth. thoughts? It is a 1990 cherokee 4.0 4x4. Thanks
