Was the distributor turned? I hear a backfire. Timing issue?

re: secondary battery. If it's installed under the driver seat...
Your fridge relay (shiny metal case) is likely in the battery box
under driver seat.
This relay is connected to the 50 circuit via a red-black wire.
In Bentley diagrams, I see 50 from ignition switch also connects
to the fuel pump relay. I assume that when cranking the engine,
power from 50 enables the fuel pump relay to close and operate
the fuel pump.
If someone messed up the 50 connection to the fridge relay,
maybe this is interfering with power to fuel pump relay
while cranking the engine ??

Also, if you're keeping the starter turning while engine is firing,
would suggest you not do that!   ;)
