No igniter in a Renix dizzy. There are gonna be a multitude of issues to deal with as stated above. Here's something to do for sure.

I suggest unplugging every connection in the engine bay you can find, spraying it out with a good electronics cleaner, visually inspecting the terminals, and adding dielectric grease before plugging it back together.
All of the relays should be removed, the terminals wire-brushed until shiny, and the receptacles sprayed out with contact cleaner. Then dielectric grease should be added before plugging them back in. I do this on every Renix era Jeep I purchase or work on for someone else.

 

You said you think the fuel pump is not working.. I would start by turning the key to ON position and see if you can hear the short hiss of the pump. Also have your friend crank the motor over and YOU look at the plug so you can confirm if its sparking or not.
