this may be coming from an axle"{ wind up" situation occurring when the diff between the front and rear diffs is not working properly. If you have traction control I would suspect a faulty sensor. Have the fault codes read to make sure

i don't know. please make sure you have fuel and leave the gas cap loose once. my guess is check position of ignition wires, if you had them disconnected. next, if you have them, , i would try using your previous ignition control and then coil.

Could be that you need to add a lil more fluid to it.

If security light is on, turn the key on and it may take 15-20 min for it to reset. Turn key back to off and then try to restart. Security light should be off and it it should start. If you for instance use a key, like a spare that you have not been using, security system may recognize a difference (because of wear, etc) and think someone is trying to steal it. Good chance that will work. Secuirty system sounds to be the problem.

Check if the heater fan works, check pollen filters.

Check your operators manual for the locations of the fuses.

It has to be drilled out, until you can turn it to the run position to push the button to release it.

Hi Linda, There are a few things that could be causing a miss and stall. However one of the first things I would suggest is to look for a vacuum leak. I experienced this same situation. I found the leaking hose that led to my throttle body. Once replaced the van ran fine. The safest way to check for a leak is purchase one of those small propane bottles used for camping along with the valve attachment to run a torch off the bottle. You will want to get about a 3 foot piece of rubber hose that would fit over the torch end snuggly. Start your vehicle and let it warm up...then open the valve on the propane bottle and take your free end of the hose and start running it around the small hoses in and around your air cleaner, throttle body etc. Be very careful because you are going to leaning into the motor compartment. It's called a motor compartment for a reason, its for motors ..not people. (smile) So watch out for the fan that will be turning at high speed...make sure that you have nothing hanging, including hair, that can get caught up in the fan. Make sure that your skin does not come in contact with anything hot. As you run the propane hose along the other hoses make sure that you are listening for the idle in your van to change. If you find a hose where this occurs. It will need to be replaced. Don't stop there. You don't want to go through the steps of replacing the hose only to find out the problem remains. You could have more than one hose leaking. Note each of the hoses that need to be replaced including where the hose is connected on both ends and the length of the hose. I prefer to take one end loose and cut a piece of the hose I want to replace with me to the shop to purchase a new hose. Taking photos, making notes and marking the hose with tape helps you make sure you are putting hoses back correctly. Finally, if you choose to replace the hoses yourself, make sure that you replace the hoses one at a time so you won't get mixed up. I will usually take one end of the old hose off and place the new hose on the connection point. I then will run the new hose along the path of the old hose until I reach the second connection point and cut the new hose to the proper length. At this point I remove the old hose from the second connection point and connect the cut end of the new hose. That will complete the repair of that hose and I can move on to the next hose to repair. I hope this helps you as I suspect that this is a vacuum leak. My Best Tony

I think you mean DIFFERENTIAL. That is the pumpkin like thing on the rear axle. How to fix depends on what is wrong. Sometimes it is easier to replace that to repair.

get a Haynes repair manual

Sounds like the problem is no spark to plugs. check for spark to and from coils. also the wires and spark plugs. It needs spark and fuel to start. If check engine light is on, Its a possibility that its a bad cam sensor. Check above first! If light is on you can go to any auto parts store so they can read the codes, with a scanner for free. and tell you the problem area. Good-Day!

Check your brake cable.

There is many issues that could be causing that... Check first that your battery is connected securely. If it is, or if you have a check engine light: take it to a mechanic.

you will have to bleed some off the freon off of the high side safety. Use a hose combo with gauges.
