Hi tried easy start even tried butain but still not even a sound of it trying to fire streached the springs on the spark plug ingition modual to make sur they were making still nothingIn theory you have everything correct for it to run ,
have you checked the actual fuel pressure ? it should be about 55psi
if that's ok then i would be trying a sniff or two of easy start or brake cleaner when cranking to see if it fires.
Hi thanks i can understand what you are saying the air gap resistance will change just air to air fuel mix it had a new injection unit about 2 years ago how do i prove if i have a weak spark or notI know you tested for a spark with the plugs out but if you're confident it's getting fuel to the cylinder,the timing is ok and you have good compression there's a possibility it's a weak spark,if it is weak it won't jump the gap under cylinder pressure.
any idea of what sets the fuel injector timing is it done from the crank sensor same as ignition or does something else fire the injector pulseshi I would expect something a cough or splutter of it trying to fire but nothing at all, To my limited understanding even if the fuel was injected at the wrong time it would still be in the inlet tract and sucked in when the valve opened would be different if direct injection in to the bore
Everything is reconnected checked multipl times and would expect some kind of DTC code to say something was wrong if it was not plugged in
Head was totally stripped before skimming them will normally not do any work unless totally stripped
Hi thought it might have some kind of input from both after a picture of the rear of the intake cam to check the sender is in the correct position but did not get a replyI would have thought a combination of both camshaft sensor and crank sensor.
Camshaft sensors informing ecu of cylinder order
Crank sensor informing ecu of tdc of each piston.
Did you ensure cylinder 1 was at tdc when setting mechanical timing?
The crank rotates twice for every 1 rotation of the camshafts. Just a thought.
Hi thanks thought it might need a picture of thr rear of the inlet cam to check sender position but no one on here had one to give meYes it does use both cam and crank sensors for spark and fuel delivery timing,
if it is 180deg out it would explain a lot
