标题:

Intermitten spark, turns on and runs, other times, no sparks

文本:

The Jeep was running fine then one day as I was driving down the street, it turned off while I was driving.  I pulled over and it wouldn't start.  After a while it started.  I took off and got home.  Through the days, the same problem would arise, going down the Hwy. 60 miles an hour it would just turn off!  Sometimes, it would start a few minutes later, sometimes 20, 30 minutes later but it would eventually always start.

So one time as I was getting home it happened again and I was able coast in to my drive way.  I had a friend come and crank the motor while I was checking the coil to distributor wire and there was no spark.  So, it was an electrical problem.  I changed the distributor cap, rotor, pickup coil and Crank shaft sensor.  For a couple of days, it work with no problem, so I thought I had it fixed.  Then, it happened again.  Back to square one.

The fuel pump turns on for a few seconds like it should when I turn on the key, every single time I turn on the key.  I checked the schrader valve on the fuel injectors and it gave pressured gas out of it.  So, I believe that it's not gas related.

So this is where I'm at.  Anyone else has had this kind of problem?  Any suggestions would be really appreciated.

Thank you very much---Victor
