Answer 1

do you have spark. if not then check the ignition mod. if you have spark then check to see if the fuel pump is turning on, and working.

Answer 2

Hi

You need to ascertain whether it is fuel, spark, or both which is missing.

Remove the fuel filler cap and hold your ear to the fuel filler whilst someone turns on the ignition. You should hear a 1 or 2 second pump run in the form of a buzz or a hum. If you don't hear it then you need to turn your attentions to the fuel pump relay.

Otherwise, spray some carb spray into the intake whilst someone cranks the engine over. If it starts then you are missing fuel.

If it doesn't start then remove a spark plug, dry it off, replace it, and then crank the engine over a few times. Remove the same plug again. If it is wet with fuel then you are missing spark.

However, I would guess, from the parts you have replaced, it is probably fuel which is missing.

Very best regards

Answer 3

All the things you just replaced still can not help about fuel delivery.Don't throw parts at it,get a professional.Or at least,on the fuel rail,there is a port to test fuel pressure.See if fuel come out when cranking.

Answer 4

if there is no spark check the timing belt/chain

not sure witch one this particular model has.
