One potential problem with multiple jets is if one starts while the other doesn’t but pumps fuel through.
Good engineering may help but there is a known issue there. (PM)

Tom, the key is to install two independent systems. That is two independent fuel pumps, two CPU's, two batteries, two controllers and two engine monitors. Keeping the systems separate provides an added layer of insurance.

Hi Chris, not sure if that would fix every problem. We have had a major fire in Australia possibly caused by a fuel leak from one engine while the other started - creating an ignition source. Although at work I fly with four jets I think the simplicity of simply using a larger jet would be nice, (Jet Arcus etc)

Sometimes even four jets aren't enough. 707 lost #3 due to pylon
failure, wiped off #4.

Took a special aircrew to get it back on the ground with two engines
missing and the wing damaged and on fire.
