I have a 2003 Dodge Grand Caravan, the security system will not allow it to start, is there a way to reset the security system?

SOURCE: how to Change, back three plugs on a 2003 Dodge caravan 3.3l

you need to put a ratchet ******** the front of the engine and remove the dog bone engine mount this will allow the engine to be pulled forward with strap and you can reach behind and remove the plugs or you can get them from underneath the van hand tightened with a spark plug socket and wrench if you overtighten they will break

these have lots of comon problem ie suspenion you have sway bar end link and sway bar bushing problems and the odd ball joint. engine 3.8L head gaskets, water pumps, coolant tubes rotting out, and poor radiators, trans problems lots too many to list. power window problems with switches and motors and window regulators. sory about all the bad news but if its really cheap buy it up. don't forget the cars market for private sales is really good if you are looking to buy right now. a van with 350-400km i wouldn't pay more than $1000 for it cert and etested.good luck

you should be adding the 134a to the system the low pressure switch is doing its job by not allowing the compressor to kick on, it wont kick on until there is enough 134a in the system to be above the preset pressure for the low pressure switch.

You can get free owners manuals online at:

or just type "owners manuals" in your search.

Here is a post I found that worked for my 2005 caravan.

For a 2001 Dodge Caravan: The owner's manual is vague, only stating that all fuses are under the hood in the fuse box, no diagrams. Once you have removed the fusebox cover, the diagrams for what each fuse does is provided under the lid. UNCLEARLY marked is the radio fuse, a 20amp fuse located 2nd row from top to the right of the accessory relay. It is marked: RDO/IP IGN.

Fuel system..Filter or pump..maybe clogged
Try fuel line cleaner..make sure the tank is 3/4 full.
this may help.
