Is fuel getting in there? are the plugs shot??

When mine had a firing issue i checked every sensor, timing, fuel in, 3 set's of plugs, coil pack and it turned out to be the diaphragm in the FPR was shagged and fuel was flooding the engine - new rail, clean out and a set of fresh plugs and it started.

Some points people were advising me were - are any of the wires from the loom touching the body where it goes through the bulkhead.
