My first guess would be the speed sensor on the way out.

Remove the inner handle ,unscrew or unclip the cover ,and you will find every lock s insi

Christy, make sure van is all the way up in park, grasp steering wheel and (wiggle) turn back and forth sharply while trying to get key out. If no success call a locksmith.

would you consider it a knock or a tick, does it have the 3.8L engine or what? Does it sound like it is coming from all over the engine or just in one place? How many miles on the van?

I'm not completely sure how all the chips work, but if the chip is not activated, the engine will run for 3 seconds, then shut down. It will only do this 4 or 5 times, then it will not start at all. If this is happening, then you need to have the key chipped to match the ignition/van.

You will need to pull the beauty covers off the top of the engine and you should be able to see the leak. I am not sure what size engine you are asking about but if the coolant is running out as soon as you put it in there must be a stream of water coming out of the leak. Just guessing it must be a rubber hose either from the radiator or the heater hoses. Hope this helps.

The volage being low could be alternator, but won,t cause over reving ,check throttle cable is working freely ,check clutch adjustment .

I'd start by fitting a set of new spark plugs and maybe plug wires too. It might also improve your gas mileage. I'm assuming that the 2000 engine doesn't have coil over plug ignition. If it does that makes it more expensive to change the coil packs. Obviously there can be other causes but you need workshop resources to do a full investigation.

Try checking the fluid first

Throttle position sensor

Does it run good for the brief period after it starts? Is the vehicle new to you? Does the security light come on after it starts?

ECU = engine control unit

A thumbs up would be greatly appreciated if this answer is helpful to you.

Sounds like an ecu problem.

Clean the Mass Airflow Sensor with the proper cleaner spray, perhaps it has become contaminated and isn't sensing airflow properly. Any holes torn or worn into the air duct tube from the MAF sensor to the throttle body will give any engine a fit. All intake air MUST come through the MAF sensor (and not leak in past it somewhere). Another possibility is the throttle position sensor (the throttle body) isn't working properly. A diagnostic check of stored or pending trouble codes should be read from the computer and used as a guide to assist troubleshooting the problem.

read owners manual. try under the dash board on the fire wall.

That's why they were sold

do you have to add coolant and is there a rear heater core in rear ??

Are the bolts seized or is there a release pin?

Are these factory acessories or another name brand?

Ronald, sometimes thing just don't happen like the book says so in times such as this I have been known to bring out the mig welder and fabricate a mount that will work and the modifications shouldn't be noticed from the topside of the vehicle. Be sure to use suitable materials 3/16th inch wall mild steel and that proper prep work and proper welding procedures are observed and you will have the box serve you well for years to come.
