CRC Electrical contact cleaner if you wanna clean it correctly, We didn't have anything else when our jeep died and use liquid wrench it worked. You just wanna clean any gunk that's in the connectors off.

And this is what the sensor looks like: http://www.lunghd.com/Tech_Articles/...Sensor_MAP.jpg

 

would your map sensor stop your starter from cranking

 

I don't think so, but it would stop the jeep from starting, I think its worth a shot purely because its an easy thing to do. Have you tried taking the starter into a parts store to be tested?

 

so im going to try cleaning my map sensor now ill see if it works

 

doesnt the starter normally ware out not just stop dead

 

i tried cleaning the map sensor but it wasnt a help

 

anybody have any good ideas id appreciate it

 

Have you checked your grounds? Maybe one of your battery terminals are loose.Id start with the basics before throwing parts at it.

 

what do u think about the starter being jammed

 

Absolutely not.

 

Have you cleaned your battery cables lately?

When you turn the key to ON your lights come on in the dash, right? What do they do when you turn the key to START? Do they go dim or stay bright?

 

my dash lights dont dim or anything

 

There are a few things that could cause this, but try not wasting your time checking and cleaning things that have nothing to do with cranking the engine over...

What you really need to do, if you're trying to fix this yourself, is get a volt meter. If you can't check the things we ask you to check it would be pointless.

So, check for voltage between the body and the starter. Then check for voltage to the starter from the ignition switch, this will be the small gauge wire going to the starter and obviously will only have voltage on it when the key is turned to the crank position. If you have voltage on both of these wires then remove the starter and have it checked at Advance Auto or Auto Zone.

 

If your dash lights don't dim, the starter solenoid is not getting power for some reason. Could be the ignition switch, starter solenoid, who knows? Get a voltmeter as suggested and start checking stuff.

 

If you are referring to my suggestion, it actually has something to do with the engine cranking over. Because my jeep would not start one day and all I kept getting from people were its the starter, its the cps. It turned out to be a dirty MAP sensor connector. I was only trying to make a suggestion based on my experience.
