Check to see if you are getting fire from one of the spark plugs and if you are getting fire, check to see if you are getting gas.

Jeep stalls gauges don't work windows and locks and radio don't work


when you state it wouldn't crank, do you mean the starter won't engage or that it just spins over and doesn't start? if no gauges or no starter engagement, then check the battery, battery connections,and the starter for excessive amperage draw. if the starter spins and the engine won't start, then check crankshaft position sensor first. the crank sensor is a more common failure than the distributor or any of the other things you mentioned.

I have replaced the camshaft sensor, Crankshaft sencor, computer, crankshaft pully, and new spark plugs on my 1999 Mitsubishi Eclipse and it still won't start, what could it be?


Engine needs spark, fuel and air to run. I assume the starter is turning the engine over. Have you verified you have spark at the plugs? Have you verified you have fuel pressure? Can you hear the fuel pump when you first turn the ignition key? If, yes to those, check the timing belt settings to make sure something hasn't caused the timing to change.

Can you tell me where the crankshaft sensor is located? Would this being bad make it not start sometimes? Sometimes it will start up, other times, not. Sounds like the fuel pump is not running when it...


the crank sensor is behind the crank pulley and must pull off the pulley to gain access to it and it must have the air gap set so the timing slots don`t hit it when the motor is running,this can cause your problem also if the wires rub through by the crank pulley can cause it as well.you say you don`t hear the fuel pump running when it won`t start then you need to make sure that is what is happening as this will cause an intermittent no start(pump works sometimes).do you get a 2 second run pump prime when the key is turned on and a no start then it could be the crank sensor as the computer looks for a crank signal from the crank sensor when trying to start the car.

I have a 1994 Jeep Grand Cherokee Laredo 6 Cyl. The vehicle was kind of running rough on idle. Take in consideration that I have replaced the spark plugs, spark plug wires a while ago. So I decided to...

Explain :P0320 ignition engine speed input circuit malfunction: it was driveable but it just cut off and want run at all.


My truck was doing the same thing.... replaced the crankshaft sensor first, truck would still die after about 10 minutes of idleing, it back-fired thru the engine and blew off the back of the intake manifold. Pulled the monifold, reglued end-cap and put back in truck. STILL died after idleing for 10 minutes. Code PO320 kept coming up ( crankshaft sensor) researched it and found a bad camshaft sensor can cause crankshaft sensor to act up and give code for the crankshaft sensor. Replaced camshaft sensor and the truck runs like a dream !!!!!! I believe the Manifold was cracked for a while causing the 1299 code reading ( vacuum leak) the back-fire finished it off! I would check the back of your intake manifold for a leak. The combination of fixing the vacuum leak , cam/crankshaft sensors seems to have fixed the problem. GOOD LUCK!!!
