could be a dodgy starter or alternator, so much as one bad wire can make each of them go bad

When diagnosing 'no start' problems, you have to divide the problem into two parts : Is it a fuel problem or a spark problem ? To ensure you have fuel, pour half a cup (approximately) of fuel into the intake and crank the engine. Give it a few seconds to suck through the petrol vapour.. If you are getting spark, the car will fire for a few seconds. Either that or spray some "Start Ya Bastard" into the intake instead. It contains ether, which is a bit more explosive than petrol.

So... engine does not fire at all after cranking ? It's a spark issue. Perhaps the crank angle sensor ?

You are showing dual fuel in your profile so dual fuel could be a number of things as in the gas valve is shutting off gas but the fuel valve has not opened
and so the story goes on.
You really need to contact someone who is skilled in gas/dual fuel and get them to go over the car.
And of course the question must be asked what are you trying to start it on ? LP gas or fuel.
If you are trying fuel and it has not been run on fuel for a long time then maybe try gas.
But then of course is there gas in the tank ?
