Update on NO-START after attempted tune up 200 1993

OK, after reading posts from helpful brickboarders, I have made sure of the following:
Crank at 0
both cam lobes for #1 cylinder point up
distributor rotor points to #1 spark plug (notch in side of dist body)
All 3 occur at same time, therefore timing belt,etc is correct.

Taking a suggestion, I checked the fuel pressure relief valve (covered by a cap like is found on tires) and upon pressing it with an allen wrench, NO fuel came out. This indicates that no fuel is reaching the injectors,correct? Also the #1 spark plug was bone dry when I took it out.
I will have to have the battery charged and test for fuel by dissconecting the inlet from the pump at the fuel rail.
Thanks for the help!!

    Cam lobes may be up but does the timing mark on the cam pulley line up like it should?

    Jump on the left side between fuses 4 and 6 (as Lucid reminded me not 5 & 7 like the older 85 I had) to force the fuel pumps to run. Do they run if so you have a bad fuel system relay? If the main pump isn't running try hitting it with you hand or piece of wood. If it still does not run try 12 volts directly to the pump, if it still doesn't run you need a main pump. Dan

      Fuses 5 to 7 doesn't work for LH 200 1993

      It's 4 to 6.

      The idea is to get +12V to the LEFT side of the tank pump fuse (4). That should power BOTH pumps, the way the system is wired.

      Fuse 6 is just a handy source for the +12V. Fuses 7—10 would do just as well, as they are all hot (on the LEFT side), even with the Key OFF.

      Thanks,Dan:
      I will check for the correct alignment of the cam marks. I thought I had them correctly lined up...I just thought of something. I need to check to see if the piston is actually up in the cylinder when the cam lobes are up. I will remove the #1 spark plug and feel with a wire (did this already before) to feel the piston is Will do this when it stops raining.
      gracias,
