My trusty and, so far, very reliable Aerodeck 1.8Vti refuses to start :-(
It turns over/ cranks but doesn't fire.
Have fitted new spark plugs and checked a spark is present.
Fuel pump runs for 2 secs as it should when ignition is switched on, and there is definitely pressure as evidenced by fuel present at the outlet of the fuel filter i.e. input to fuel rail.
So must be the fuel injectors ??? either all faulty (hard to believe) or not receiving their control signal from the PCM.
MIL is not indicating a fault code / DTC is present.
I can check injector resistance but it's not going to be all four.
I could check a pulse is getting to the injectors using an oscilloscope ?
I am at a loss - I guess something could be preventing the PCM from pulsing the injectors, (e.g. faulty sensor) but wouldn't that trigger a DTC ?
