Avensis D4D Wont Start

[Davy123]

Hi all...I've recently bought a 2001 D4D Avensis and there was a problem with the brakes,they worked fine until the car warmed up and tickover was normal , when you come up to a junction at tickover speed it feels like the servo aint working,give it a rev and the brakes work fine... anyway to check the servo i removed the servo pipe when car was running to see if air was being pumped and it was fine, ,car stopped , i connected pipe back up and car turns over very quickly like there is no compression.. is there a sensor or something that would stop engine because i was messing with brakes that needs reset?.. anyone any ideas...cheers Davy

I also took the timing belt cover off and timing belt is intact and turning..
