Fuel-how much pressure do you have? How quickly does the pressure fall when the key is turned off?
Spark? Are you finding spark at the coil wire, or at one of the spark plug wires?
Miles? State of tune?

Before you go into all those schematics I would ask a simple question.... When you turn the key what happens??? Nothing??? Does it at least turn over just doesnt fire up??? Turn the key and hear only one "clunk" what happens in the begining??
cranks but doesnt turn over. as for the pressure i just check the valve on the engine and alot gas squirt out. I check the spark at the coil..
crank shaft sensor? Mine went out on the D2 and just stopped at a stop sign...
sorry, did not see the year.

You sure cause I believe he just said he has spark at the coil??? Check to make sure all the injectors are pulsing..... And also check camshaft position sensor..... With nissans which is what I really know the CSPS is a very common problem.... did it have a long extended crank issue before it stopped running??

For the love of God boys, this is a '95, IT DOES NOT HAVE A CRANKSHAFT POSITION SENSOR, IT HAS A DISTRIBUTOR!
This truck fires all of the injectors for each bank simultaneously, thus if one is firing, it is likely they all are.

OK, first off, do you mean that it cranks, but does not fire?
You may have plenty of pressure at the rail, but you also may not. It doesn't take much pressure to spray it out the valve, but it does require quite a bit of pressure to make it run.
Checking at the coil gives us proof of a good ignition amplifier and coil,but tells us nothing about the cap and rotor.
Jumping to the end, I think a new rotor might just solve this issue.

If you find out what it is let me know. It just might work on the mother-in-law.
If you change the rotor do a search first. I did not and ended up pulling the insides of my distributor apart. I then had to take it apart to put all of the insides back where they went. I believe a chisel was the best option for rotor removal.
