Not cranking over?

So about a week ago I noticed my car leaking coolant. Took it to the mechanic, and he said I needed a "rear pipeline cord". After days of searching and finding nothing, I went back. He called around and informed me I had to order it from the dealership. My brother in law, cut the rotted piece of pipe, connected a hose and clamped it, so I could make until the part came in the mail. Upon driving it, it began overheating so I stopped and added coolant. Only to realize it was leaking still from the bottom of the van. So I pulled over. I waited a few hours and drove it home. The part came today and my mechanic is only 3 blocks away, so I thought I could make it to him. But when I tried to start it, it wouldn't start. No coolant leaking under the hood. It did not make any noise when I tried to start it, the radio came on and the dash lights but absolutely nothing else.

So I realized my gear shift thing, (the thing that goes from park to drive and stuff) was stuck. So when this guy inspected it, he saw it was not fully in park and that was why it wouldn't start. Turns out my "gear shift cable" was rusty and had gotten stuck somehow under the battery. A little oil and cleaning and my car was slid into park and started right up. Thank you so much though.

Thank you. You guys are such a blessing. I am 100% positive you would have gotten the right answer. It's a process online without being able to see it. I get that. But it is so wonderful to know you guys are here. Thank you.

Our van won't start. You turn the key and it won't do anything. The lights and car radio still work fine. Any idea what it could be? We have tried unlocking and locking the doors to see if that will help. Tried pulling the starter relay out and putting it back in. Nothing seems to work.

Yes, and nothing. Just a clicking sound when you turn the key

The van will not crank. Has has good battery and fuel. Diagnostic said C shaft possioning sensor. My question is where is the located and how should it be repaired

The van does not start occationally. The check engine light comes on. If the vehicle is moved (rolled) it will crank. The Auto Parts store did a Diagnostic on it and said it was the Crankshaft Positioning Sensor.
Is it hard to repair? Do you have to pull the motor or transmission to get to it? What is the normal repair cost on this?

I was at a stop light and my Kia stalled and also it wont turn over. I had alternator tested, checked out good.

After the van not wanting to accelerate over 50mph, we have had the fuel pump and filter replaced, the map sensor, spark plugs, wires, and various other parts replaced. The battery is good, the alternator and starter are fine, and the timing belt is good. We have put 5 gallons of fresh gas in and it still will not crank. Any suggestions on what to do next?

My Kia stopped running. I put a cam shaft sensor on because it had a crack in it. It ran good all afternoon. I cranked it up and it cut back off and now it want crank again. Do you have any suggestions for me to check? I tested the crank sensor and it was working before I checked the cam shaft sensor. Could the fuel filter have anything to do with this problem?
