Jeep won't turn over

Asked by May 15, 2017 at 08:21 PM about the 2003 Jeep Grand Cherokee Laredo 4WD

Question type: Maintenance & Repair

I have a 2003 jeep grand Cherokee that won't start.
I took it to go get it diagnosed and they told me it
was the crankshaft sensor, so I replaced that and
after I did, it ran fine. The very next morning it
decided to not want to start. It sounds like it has
the ability to want to start but won't. I've asked
around and everyone is telling me it's the fuel filter
or the spark plugs but I want to be more sure then
that before I take it apart and blow a bunch of
money. If anyone could help me it would be very
appreciated!

If it is showing a check engine light, there will be fault code stored in the computer. Without starting the engine, turn the ignition key ON, OFF, ON, OFF, ON. Leave it on and write down the code(s) displayed on the odometer. When it is done it will show the word "done". Or of there is no codes it will simply show "done". Go online and look up the codes. However, not all failures will show a code. I hope this helps.
