Hi,
I'm not an Auto Elec, but.. don't try & bypass the Relay. It's there for a good reason, so as not to burn out your electrical system, see, it act's as a separate switch, thus reducing the Current, or load on the switch/s.

Any spark or ignition point around the fuel system, would be a catastrophic event!!

Unfortunately, any vehicle which sits for a year will be plagued with a number of faults

Poor battery current/voltage, OVR,(over voltage relay) & or fuse, the fuse box it's self, fuel relay, any earth straps, all usually attributed to poor contact & or corrosion. Hence no running engine.

A quick test for battery power, is put your headlights on high beam, and if not bright, especially while cranking the engine, that would be a good place to start with.

If unable to drain the fuel tank, then at least fill it up with fresh fuel. Fuel is usually only good for up to 4-6 months, depending on the type, your environment, etc. Don't worry if it doesn't fire up straight away, it will take a short time to purge thru.

When the ignition switch is turned on, a wirring sound should be audible. If not, fuse or pump,or relay and fuel filter could all be possible causes. If problem persists, suggest you get a qualified technician to assess the situation.

Don't forget about the engine oil change and filter change, cause a gummed up engine and or valve train won't help your situation, as by now, oil / water & fuel contamination will be present!

So once again, check the battery and terminals fill up the fuel tank with fresh fuel, change your engine oil and filter, and you will have to work, one step at a time from there.

Get back to me once this is done if you still have problems.
