Still no go... Here's what I did so far:
Crank Position Sensor showed resistance so I replaced it.
Cam Position Sensor tested good.
Fuel pressure at 49 PSI.
Spark from all wires.
Watched distributor rotor for smooth rotation. No indication of broken cam
or distributor teeth.
Looked for any signs of wire harness corrosion and checked all grounds.
After all that...Replaced PCM! And...STILL NO GO!!!
I could check voltage at the injector PCM pins but a new PCM should have
fixed that.
How about a broken timing chain. Is removing the valve cover the easiest
way to check for that?
Any other ideas are greatly appreciated!
Thanks,
James

Well I tested the CPS as per the FSM and it showed resistance so I replaced
it, however the truck still won't start. I checked the CPS and it shows the
fluctuating voltage as per the FSM so it appears to be good. Cap and rotor
appear fine. Fuel pressure at 49 PSI. Still no codes. I'm going to check
what the voltage should be at the injectors. Right now the meter shows only
2.5 volts but it's a digital volt meter. I believe an analog meter is better
for testing quickly fluctuating voltage.
Any other suggestions are greatly appreciated!

Well, 120 is kinda well before those sensors seem to want to fail. If yours
is a 96, you should have OBDII. A reader might solve the problem real fast.
Especially if you get a P1xxx code. Those are the manufacturer-specific
codes. I've heard of one that says "disagreement between cam and crank
position sensor signals. I think it was P1903. Since you have the FSM, it
should tell you what you need. Biff
