It cranks really quick so don't think it is battery. It has almost a full tank of fuel.
Have removed a spark plug and grounded it to the motor - spark is there but weak (orange, can't hear a noise either) and seems intermittent. Tried again, this time attaching a jumper cable to end of plug and grounding that to one of the nuts on top of the right strut - same issue. Plug is wet with fuel. Car smells faintly of fuel after cranking for ~5 seconds.
I loosened the nut on the engine side of the fuel filter and fuel comes "censored" out when the car is cranked.
So, I guess that suggests it is either the weak spark that is the issue, or perhaps the timing belt has slipped?
Should I be looking at getting a new coil and igniter? Any other suggestions from anyone? What's the easiest way to see if the belt has slipped.
Thanks for your time,
