2003 Td4 wont start, please help..

The starter is spinning fast, thiers plenty of fuel, I've disconnected one of the fuel pipes and turned the engine and the fuel flows nicely. Has anyone got any ideas...The maf sensor has been disconnected for a while as thats faulty but i know the car runs ok without it although smokey. Reconnected it anyway and it had a breather kit last year, what should i try now. Cheers. Oh, Its been taking longer to start for a few weeks now until this morning when it stopped altogether. Its also had injector cleaner treatment recently.

try a quick squirt of easy start to see if it will start then. If it doesn't, my money is on the crankshaft sensor.

sounds like failing (failed) injector, leaking back.

like ratty says, try easy start and see if it fires
