If its the 3.0 diesel you have a glowplug fault .
May just be the 40 amp one under the hood or one or more glowplugs have burnt out they can be tested in place by using the ohms on a multimeter - O reading duff plug - 0.8 - 1.0 ok.
Also check for 12v on the plugs as the relays can go too .

check air filter, fuel filter, and spark plugs in that order. make sure you check all fluid levels too.

I have trouble starting my 313 cdi van. Its a 2003 model. When I spray ether into the air filter, it starts. I know the glow plugs need replacing, but even on warm days it wont start. Any ideas?

Hi, My thoughts exactly ( fuel leak). Is this a deisel or gas engine?
In both cases be very careful with lights or cigarettes.
You can smell it when you get out of car in a garage or stall.
Good luck.
