Hi, my transporter broke down a few weeks ago....the fuel timing belt
snapped.
i have taken it to a friend who owns a car shop...hes not great on diesels
so has got a friend of his in to change the fuel pump...time it up... etc....
i bought a used one from the same modal van....
now this guy has fitted the pump and changed the ecu from my old pump on to
the working one but it will not start????
he say there is fuel getting to the engine...but for some reson will not
turn over...
he suspects its an electrical fault????
is it common for this to happen???
is there any thing i could check or do?????
any help would be great....im pulling my hair out now...
thanks Jim.

If the timing belt snapped then you prob got some bend valves. Do a
compression test and if it's low then replace/repair cyl. head.

Hi its the timing belt for the fuel pump not the cylinder head...its on the
other side of the engine.....it controls the fuel timing only....

Is the man who fitted the belt known by you to be the genuine article i.e.
have real knowledge, or is he just full of confidence?

If it ran before the belt broke it should run now, if the timing is correct.
That's my favourite for a diagnosis.

Son-in-law had one of those (2.5 transporter). So I know the setup and I
never tackle anything like that just thinking I know how to do it. There are
some that think they do but not many outside garages.

hi yeah....hes a diesel mechanic and is a friend of my friend......hes been
scratching his head why it wont start....hes convinced its an electrical
fault....but it seems strange to have two faults at the same time?????
i was wondering if the fuel pump going could have caused a relay or fuse to
blow????

Only other thing I can think of is has the stop solenoid stuck on? i.e. when
you turn the "ignition" key to the stop position there is normally a
solenoid that causes the injector pump to go to the zero inject position in
order to stop the engine. You can usually hear it release a few seconds
after the engine stops in order to allow the next start to take place. If
that sticks in the off position it'll crank until hell freezes over without
result.

Just a thought.

Could be, but it *could* be anything. VCDS is the first step.
