Hi all,
My friend has a jeep cherokee larado 4.0l engine 4 w drive larado 1999.
The jeep now has some intermitten starting problems.( no check engine light comes on/no obd codes show up).It will fire up great 9 times out of 10..the 10th time the engine will try to turn over/fan will turn/motor will shake etc.
I let it cool and then eventually it fires right back up multiple times in a row??? Like a champ..no hesititation..no pregnant pause..no chattering
Now some would say that it is a starter problem. But the car also has some intermitten stalling problems as well......but let me go on.
I drove the car up the interstate 88 mph..no hesitation..no dragging..lots of power...transmition changed up smoothly.
My friend called me up and said the car won't start??? the same jeep I had up the highway the other day..
It eventually starter and we drove it home. I put brand new spark plugs in the jeep that night. Battery read at 12.6 at rest..13.7 while running.
My friends' wife took the jeep to a yard sale..it started up fine but then she put it in reverse and gave it some gas..the car stalled??
The car wouldn't start back up again.
I came over like 10 minutes later..told her not to keep cranking on that starter. It cooled and immediately started..she made it home like 3 miles away without any problems?
okay what could it be..one minute it drives fine..one minute it starts great 9 times in a row..another time it won't start and another will stall while driving.
Then I still can take the jeep up the road and do 70mph in it without any problems??
so am I not getting fuel..spark? what would cause the non starts AND stalling?.. something broken inside? then why could I drive the hell out the jeep the next minute later? He normally keeps like 1/4 in jeep..hard on fuel pump but no noticeable noise/strain pump noise..fuel pump relay buzzes/comes on line
Funny how originally the jeep wouldn't start in the garage..let it sit overnight and it started right up the next day..nothing was touched..
so I don't think it is broken wiring in like the circuit
Could it be bad gas? vapor lock problem?
