The old "it ran when I parked it", Yes it's been sitting out of the way for a while (+1 year) and yes it was running and running great (that 3.3 V6 is a nice engine). New battery and cranks but just won't fire or even pop. Suspect the fuel pump seized but it seems to or sounds like it's working but no evidence of fuel in the cylinders? Sprayed a little contact and starter fluid in the air intake and still nothing. Going to check for spark but ran across a youboob video that claims it might just be a relay for shutting down the fuel??? It wasn't specific as to which or where it is but I got the impression it is one of the three in the attached photo?? If it is I'll jump it if I can figure out how but first I have to figure out if it even is one of these or if I'm wasting time. Thanks in advance as usual for Moparts help up

Mike

As a famous and wealthy owner of a C14,car .... isn’t it time you MOVE UP in the Mopar world with at least a 01 or so ?

No fire with starting fluid ? ... no sparky is the issue tsk

A service manual for your van is your helpful friend. It should show what relay is for the fuel pump. You can remove the return line and jump the fuel pump relay to see if its pumping.
