Engine all of a sudden the engine won,t start unless you hold down throttle and the cooling fan doesn,t come on unlee you turn on tha air cond. Sometimes the engine idles ok and the cooling fan doesn,t come on still.
Coolant temp sensor tells the computer how hot or cold the engine is so it can regulate the idle and fuel mixture, when it fails there usually is no cooling fan and you will have trouble starting the engine and keeping it running.

I was browsing unsolved problems. If you still have the problem, I'll try to help you. But it's going to be awhile trying to communicate back and forth. First...Check the engine for spark. Take off a plug wire and stick a screw driver in the wire end and place the metal part of the screw driver next to something on the van that's metal. Have someone crank it over for just a second or two and see if a small spark jumps from the screw driver to the metal part. I'll check back for your answer.
I had the same thing happen to me...fans would run even when car turned off. Was the thermostat. Got one with high temp-92* I think, it did the trick!

Hello there, As far as the check engine light I would think since you mentioned it shacking that your light will probably be on for a misfire, Meaning most likely you have a spark plug wire going bad. I would stop by somewhere such as Autozone for a free check to tell you why your light is on just to double check.
Your fan issue could be several different things such as the fan motor going bad or the blades could be rubbing something, that one is a little tricky without hearing it.
Good Luck and I hope this does help you some. Allen
