Ignition switch,bad fusible links, coil,ignition module. I have replaced several switches for this problem. At the coil, when you turn the switch on, there should be power. There also should be power when trying to start the engine. If there is no power while cranking, replace the switch. The reason it hits a cylinder or two is that the power goes to the coil, just not enough to get the engine running..

Yes, you need to remove tank.
There is a fuel pump test connector, either a single wire connector in engine compartment, left side, OR terminal G of the ALCL, the diagnostic test connector under the dash. Put battery voltage there and see if pump works.
Diagram also shows a fuse for the pump, probably in the dash's fusebox.The relay is probably is there also.

If you are going to attempt this repair and have never done this level of work you had better buy a manual. It's not something that can be described here.

You need to have the choke adjusted so it runs on a fast idle so the engine can warm up or you may need the carb to be rebuild and adjusted properly.

Change the battery. Newer batteries sometimes go all at once, and are so dead even a jump start won't work. It has happened to me twice. Once you put in the new battery check the alt output with a volt meter should read about 14.5 volts at the battery. If it does problem solved just reset the clock, radio etc.
