Your going to need more help than I can give you. Yea, on a Renix <90, that's one hallmark of a bad CPS, cutting out. If you have good spark and fuel maybe it's flooded. Smell gas? Plugs wet? If the MAP sensor there up on the firewall isn't getting good vacuum it would dump fuel...maybe flood it.

CPS=Camshaft Position Sensor.
CKP=Crankshaft Position Sensor.

Both easy to replace.

LYNSKY...both have been replaced.

DF...when I pulled the spark plug out to check the spark....it smelled like gas. I did put a new o2 sensor in afew weeks ago.

"or vent solenoid circuits open or shorted" Have you by chance been topping it off when you fill the tank?

I was going to see if you can feel vacuum at the MAP, but if its not running....That little tube out of the rubber plug on the throttle body, back to the map, breaks and splits allot. If there is a leak the MAP will run it rich. You might check that any day.

Was there any black smoke?

douglasstorm

No black smoke...but after I drive it and try to restart it there is a horrible burning/musty/gas like smell.

If I can get it started in the morning I will check the vacuum at the map. From the research that I have been doing some say it could be a vacuum leak somewhere.

Thanks again for all the help!!

Ok..I just mentioned filling it because the vent tube goes to that solenoid you got a code for, and it might maybe be rich that way. Don't know if it can flood itself with the evap canister, or not.

OK guys so this morning started up the jeep and it fired after a real short crank...which is weird. So with it running I took carb cleaner and started spraying it around the injectors to see if I might have a vacuum leak somewhere. Well 1,2,3,4,5 had no change in the sound of the engine but when I hit the 6th injector it idled down alittle. I did it like 3 times and every time it idled down. Could this be a issue?? If so could it be a ring on the injector that is leaking air??

DFlintstone

Yea, mine did exactly that, #5. On my 90 Renix it wasn't that big a deal. Might have hurt my mileage if it was lowering the Vac to the MAP, really can't say for sure. Would stumble or almost miss at idle.

douglasstorm

Yeah DF that is what mine is doing. So I decided to pull the injectors and check the rings...but they are all ok. No more progress on the 2 big issues but on the bright side I got a chance to clean all the black crud off the injectors and in each hole in the intake!!
