My 89 cherokee is my daily driver as well as my toy. but recently it has developed an inconsistent starting problem. sometimes after long and short periods of time it will just crank over n over then finally it will start, but most of the time it fires up like a champ. i have replaced the fuel pump, filter, put a water absorber in the tank (HEET), and seafoamed the engine to try an fix this problem. everything i can spot is in working order. plz any suggestions welcome. i just dont want to keep throwing money around and not fixing the problem.

thanks for the help

 

check out the cps yet??

 

what is CPS?

 

CPS is crankshaft posistion sensor.

my guess is the NSS: neutral safety switch.

GL

 

i dunno if thats it, cuz it will just keep crankin then i wait then i crank it again and after a few times it starts.

 

So whats the problem then

 

I think his point was if it were the NSS it wouldnt crank at all, Really no need to be a smart ***

 

get a haynes boy!!!! but your CPS looks like this....

sorry couldnt upload any pics of it but i googled a pic instead. its infront of your jeep right next to your radiator. easy access ;]]

 

shut your mouth when you are talking to me

 

My mouth wasnt open when I typed that! haha

 

this.

If it still starts then whats the problem.. All of our jeeps have little quirky electrical bugs. as long as it runs then its fine with me

 

OOOOOOOOOOO I thought you were bein a prik and ment it in another way my bad for the misunderstanding. I agree tho, find me a jeep thats been ridden hard that is perfect... you cant lol My bad again reno

 

It's all good man no hard feelins

 

Kevin. I would take a look at the crank position sensor first. If thats not it your intake mani may need a good cleanin. I recently took out all the vacuum fittings and lines and cleaned all the gunk out it idles much smoother. Couldnt hurt.

 

the picture is great but where is that located? my real problem is the fact that it just cranks for days sometimes, then other times it fires up like its brand new?
