i have a 1990 jeep i was driving than it just died and would not start towed it home it start today if you give it gas it some time pops and other time just dies and no it was no spark
It's usually (incorrectly) called the CPS sensor.
OK, that last part is actually normally. Are you saying it will not run, idle, start, with the vac line connected to the MAP sensor?if you un plug the vac line to the map Sensor it will run. if you give it gas it will die
it will run with the map unplug it was fuel and spark
Why do think it is the CPS? He has just said it runs with the map unplugged?search for crankshaft position sensor and you should find a step by step way to tell you how to fix it or at least diagnose what's going on better.
it has a new fuel pump and fuel filter i am unplugging the vacumn line to the MAP
