Question about 1987 Jeep Comanche
Hi all, I have a 4.0 that on ocasion wont start unless you push startit. Sometimes you have to just pop the clutch and it will start andsometimes you have to go a hundred feet before it starts. Sometimeswhile running it acts like the choke is on and wants to die. We havereplaced the crank sensor and computer but it is still doing the samething. I was told to buy a factory crank sensor not aftermarket as thefirst one didnt work. looking back I dont think the crank sensor orcomputer is the culpret as it is still not starting all the time. Alsowhen cranking it over it has this funny hesitation and if you let offthe key at that moment it wont start when you try again but if you keepcranking through it it will start. Any thoughts? Thanks TAG
Check spark quality...it not only need spark, it needs good spark (should bridge at least a 1/4" gap with a strong snap and blue color.) Also, make sure engine timing is correct...If you don't have a "locked distributor" sometimes it may need adjustment. Incorrect timing can make the engine "kick back" when starting, or "lay down" while driving.
