Is there any way to jump a connection/terminal underhood of a '93 Caravan to test the fuel pump?

Been chasing a 'no start' issue. Yesterday, I could clearly hear the fuel pump kick on, when I'd cycle the key, now, silence.

I'm at a loss trying to diagnose this thing, and having a generic haynes manual isn't helping.

Or, am I missing something else?

Find the ASD and fuel pump relays.Then have someone cycle the key.They should click.Listen at the fuel inlet also when cycling the key.Best way is ckecking with a fuel pressure gauge.The relay can be swapped as they use mostly the same relays in the box.Also try smacking the tank with a rubber hammer as someone cranks it.Most times if the pump isnt totally gone the shock will get it going.Rocky

I disconnected the battery to 'reset' the computer, the fuel pump works again.

I'm not getting any spark.

Going out to check wiring.

The problem I'm having is that I can test wires all day with my dvom, but, unless its something obvious, I don't know what I'm looking at.

Yeah, I know I should get rid of it, but, I paid $200 for it 34K miles ago, and the only time it gives me fits is when I have to jack with it to try to pass emissions. For all the posts I've had on here about this van, I still have less then $900 into it, including the purchase price. I've paid a LOT more for heaps that were much worse.
