Ford computers Prime the fuel system for 2 seconds when key is turn on, this means fuel pump runs for 2 seconds, but only 2 seconds
So you may want to:
turn key on
Count to 3
turn key off
Repeat 2 or 3 times to build up fuel pressure
No, you can't build up too much pressure
Just to narrow down possible problem points, get a can of Starting Fluid(ether).
Remove Power Brake vacuum hose or PCV Valve hose from upper intake manifold.
Spray Starting fluid into intake, replace hose.
Try to start engine
If it fires up and then dies, you have a fuel problem.
If it doesn't fire at all then spark is the problem.
