Possibly - Where is the throttle quadrant ? - might be worth posting a pic up of the throttle quadrant - we can tell you if it is the right place for tickover .. though you may know this already - Does the accelerator pedal work as expected - or it is stuck down ?
It does
sound like a seized governor - though it might simply be the fuel/boost pin - you should find the rebuild manual online for the Bosch VE pump - which will point you in the direction of the bits that can stick - and where to
tap the pump body gently to aid release
- or whether, as Turboman says, above - the actual governor can be got at from outside the FIP.... .....
