Car engine will not crank

Durangos are known for crank sensors to go bad. Make sure that your battery is fully charged so you know that isn't an issue. If you don't have the proper equipment, try this.. Your going to need someone else's help for this. Pull one of the spark plug wires, using a screwdriver, put the tip of the screwdriver into the wire and hold the shaft of the screwdriver about a quarter inch away from a good ground source. Have your assistant turn the key and crank the engine while you check to see if you have spark. If you can, visit your local parts store and ask for a noid light that will fit your vehicle. It's usually about $10-$12. The purpose of the noid light is to check for injector pulse. Disconnect the plug for the injector and connect the noid light in it's place. Once again, crank the engine and check to see if the noid light lights up and pulses. If the crank sensor is bad, you should have no spark and no injector pulse. Replace crank sensor if so. If you have spark, check for fuel and or fuel pressure. Listen for the fuel pump to energize when the key is turned. Also try spraying starting fluid into the throttle body. If it starts, your having fuel issues. I hope these tips help. Good luck.

Hi Sheila, i'm glad to help. 99 Durango's with thew 5.2 liter engine were good about the Crank Sensors going bad. Now, as I can't say that securily with out diagnosis. If it were my vehicle and knowing what I know about no starts, that is diffinently where I would start. Hope this helps and have an awesome day Sheila.

Check for fuel pump when u turn on key it should prime for 5 seconds. Then it could aslo be a crank sensor or cam sensor more info need . May be even a timing belt check compression

A good hot battery shoulde do it. Have you had any problems with the security system? That's all that should keep it from starting now. Have you put a socket on the crank bolt to make sure the engine is not seized and turns freely?
Good luck.

How's your battery ?


Turn on your headlights , then crank enging , IF lights dim completely its a battery condition problem. If the lights stay on full and you just get a click sound it the starter motor (conection or condition)
Good Luck

Is the clicking sound from under the dash or under the hood? Does the engine crank over?

have you checked the battery and the cables?
put a wrench on the crank pulley,you should be able to turn it .that would rule out the engine is not seized.
a click like that can result from a bad connection on the battery.
jumpstart it being careful about polarity and put the ground on the engine,not the battery

If you haven't had an alternator / charging warning light on, i would suggest it's the battery, or dirty connections.

I put in a new crank positioning sensor and it fixed my problem. 42.00 dollars from NAPA. took about 2 hours to change it.

that click noise is nothing! when you put neg post on then positive sparky? if so probably solenoid circuit ignition on starter will draw power but will "NOT " engaged until you crank Key!!
