Check the cap and rotor. Spark plugs. Could just need a tune up. Run some injector cleaner through it. Fuel pump may be a little weak.
Possible fuel pump. Try turning the ignition key on 3 or 4 times before cranking the engine over. This allows the fule pressure to build up. Hook up a gauge to check the pressure.

Have u checked for vacuum leaks or poss leaking EGR valve? use carb spray around the upper intake manifold where it bolts to the lower manifold, spray vacuum lines where they are connected to the engine vacuum ports, the idle speed will change if u hit a leak, as far as the EGR valve goes see if it gets hot at idle, if it does it is leaking, if all checks ok replace the O2 sensor, but i suspect u will find a leak at the upper intake plenum.

Loose connection is the problem. It takes petience to find where it is at. Do some wiggling on wires to see where it is.

try cleaning the connector that goes to the fuel pump, sometimes they corrode on inside. If that does not fix, test the wires feeding fuel pump with a multi meter until the condition shows itself again, if voltage drops to zero or very low then wiring problem, if voltage is unchanged with problem and fuel pump is not working and connectors are all clean, try replacement of fuel pump.

are u referring to the IRCM? (Integrated relay control module), when u say proper placement what do u mean by this? Have u run a test of the IRCM with a OBD2 scanner, It will produce a code if it is the problem, if u have not scanned the system I strongly suggest you scan the system which will run the IRCM through an active functional test. B3below is the proper relay that a trusted on line parts dealer shows for this van and it does cross over to the ford number u gave.
