Hi all , just had a firing issue which turned out to be the ECU getting hot from a wiring problem, that sorted now it has pulse and spark whilst trying to fire. Now it seems to pressurize the inlet manifold hence not allowing the ignition to happen, have had it suggested a stuck valve, but I was running the car only days before. Can this be sorted by removing the rocker cover backing off the tappet and using a plastic hammer to free the valve, or is it head off.
Thanks for any input...
