Sounds to me like the ole lousy crimp connector on the end of a wire. When cold the crimp is good enough to work, but as it warms the crimp looses its grip a tad and things start to go down hill. Find feeds to fuse box and solder any wire crimps to get a good connection. Had this happen on a new chevy starter, same complaint.
good luck

Spray some carburetor cleaner into the engine an see if it starts ! I don't think 58 psi fuel pressure is enought ! Has to be above 60 psi .415-455 kPa (60-66 psi).

For initial prime, you have to check fuel pump relay and wiring circuits. The control/coil side of relay gets voltage from pcm, green wire with white tracer. The ground for control side of relay, should be a chassis ground. Voltage for load side of relay is fuse protected.
This vehicle has an oil pressure switch in fuel pump circuit, just a redundant power supply to the fuel pump. Even w/o the relay the vehicle should start and run, once the oil pressure builds up and that switch closes, the fuel pump will get voltage. There won't be any initial prime w/o the relay.

are you sure the coil is bad and not a problem with the module in the distributor,you could try unplugging the tan wire with black stripe, connector near distributor and see if it starts, in 26 years ive seen alot more module failures than coil failures.

Sounds like a bad ground. Inspect your battery battery cables to start.....

What has happened is that the link rod connector, a plastic piece, has broken, and the rod is indeed flopping around in there. These are always fun, as they never break after the door is already open; it is always the act of opening the door which breaks them. The parts are cheap, less than $5, but getting to them...not so great.
To further assist you, I need to know which rear-door configuration your van has. Please respond if you still have the vehicle and the problem.
