I need to find what relay is aside of the single module engine controller. Also, I cannot find a wiring schematic listing parts of the electrical system and location of parts. I'm looking for all options as to why my vehicle is refusing to start due to this relay or other source of problem.

Which van? Caravan--grand caravan--ram van. Litre size of engine? If it cranks good but won't start, have a helper crank it while you visually check for spark at the spark plugs. If you have spark everywhere, check fuel pressure. Check for applicable mil codes. You should be able to check those codes, yourself.

Just to add, if no spark or fuel injector pulse, check primary voltage to those two items, engine cranking. If no voltage, I'd have to cam and crank signals, where applicable. If the computer doesn't see those two signals where needed, engine cranking, the computer won't ground the asd relay. The asd relay supplies voltage to several systems.

How long since a tune-up?

Recap on 1994 dodge van b-250: it starts when it wants to &when it does starts it runs fine but when it doesnt start the check engine light doesnt light up either. So someone suggested to replace the ADS relay &fuel pump relay &i decided to pull & disconnect the starter relay & rehook up to have that fail ( wouldntcrank) so I guess I im gonna replace the starter relay & also the one next to the single module engine controller provided that I can find out what that one is!
