If your van is designed like later model vans it sounds like you lost the camshaft or crankshaft sensor signal. If the engine computer doesn't see this, it will remove the ground from the Automatic Shutdown (ASD) relay. This action opens the ASD relay contacts, cutting power to the ignition coil, fuel injectors and fuel pump and O2 sensors. Ckeck for power at the sensors and injectors. If there's no power then the sensors or their wire harness and connections are suspect.

It has a fusible link. Power comes into the ASD relay on the red wire witha white tracer. The fusible link is white. Possibly your timing belt has gone out ; remove your distributor cap and have someone crank the engine and see if the rotop turns. It's a non interference eng.

ok i looked at all the fuse links i could find and they tested fine power in and out.... but i didnt find one for the coil... the timeing belt is good... I was told maybe the roll over switch was tripped where is it at?

Doesn't have a roll over switch. Fusible link feeds the asd relay not the coil. Do you have power on the red wire with a white tracer at the asd relay with the key in the run or start position?

I asume that the asd relay is the plastic one? I do have power at the red/w wire in start and run

looking on autozone I dont see a crank or cam sensor listed allso I dont remeber putting one in when I did my 2.5 turbo in my other van

Wires at relay are dark blue. 2 dark blue with a yellow tracer at one post. Red with white tracer and last one is dark green with a black tracer.

There is a pickup coil in the distributor.
