Bleedin' diesels
I made a thread a few months ago about a saab 93 2.2TD that has seized glow plugs. I've had the cylinder head off and got them drilled out and
refit the cylinder head with a new gasket, glow plugs, cam sprocket bolt and upper timing chain guide bolts (as per haynes manual) I've
reconnected everything and filled fluids up and now it won't start.
In the haynes manual it says the fuel system is self priming and you need to turn the engine over for 10 seconds, let it rest for 5, then turn over
for 10, repeat... but it's still not starting. Could there be loads of air trapped still, I've had all the fuel lines in the engine bay
out. I'm wondering what to do next. Also i don't know how fast it should be cranking over, I charge the battery for a couple of hours on
trickle charge then crank it over and it's pretty much flat after a couple of minutes cranking (with breaks to go easy on the starter) New
battery needed?

I had a similar problem on my mondeo tdci
i basicly filled up the fuel system from the engine end using a funnell and some fuel hose having taken out the schaeder valve. also crack open one
injector (mine is common rail) and let fuel out
it was a bit of a messy (diesel !!!) job, but once the valve was put back, it started first time

That took you 12 hours???? 
Have you tried cracking the fuel lines or removing the leak off pipes and turning it over to see if fuel is coming out?
How long can i resist the temptation to drop a V8 in?

Do not crack common rail diesel injectors. They are under such high pressure you
could get seriously hurt.
Does it have the vauxhall engine in it? If it does there is an electric pump in the tank that will prime the system when you turn the ignition on.
To check this disconect the fuel feed pipe at the engine and put it into a can, turn the ignition on an see what happens. If i remember correctly the
pump will prime for about 30 seconds so make sure you have a big enough can.

Fords can be a bitch to prime as they don't have an electric pump or manual squeezy pump. A squirt of carb cleaner down the intake pipe can get
them going if they aren't too air locked.

Easy Start
Spray some easy start in the air intake, not much but a good squirt.
That will run the engine and should prime it at the same time. Works great to get you out of trouble if you have an injector leaking back.

Not sure. It's got GM stamps on it...

it will be a 2.2 vauxhall dti. and your problem is an airlock in the mechanical fuel pump
here you go
do this (compliments to celes on the vauxhall forums)
Common problem on diesels after fuel filter change and since the DTi's only have 1 pump they're that bit more difficult to start after a
service.
What's happened to me is that the car started right up and ran OK. I then went in to wash my hands and have a drink and when I came back it
wouldn't start! Blooming thing sucked in air instead of diesel!
Here's what you do if your DTi (or any other diesel for that matter) refuses to start after a fuel filter change.
For this job you will need a socket 10 to remove the engine cover and these babies, size 8 and 17:
After you've removed the engine cover locate the boost sensor:
It's held by a size 8 bolt on the back. Remove the sensor carefuly not to drop the bolt or sensor.
After you've done this, locate the fuel line that goes into the cylinder number 4.
Untight it using the spanner size 17. Now you'll need a hand. Ask a mate to crank the car while you watch the fuel line. When diesel starts to
drip out tight it back and put the boost sensor back in place. Try to start the car again...It should start quickly

Would it be any help to put a manual primer (from a scrap car maybe) in the supply pipe if there's no primer pump? I only ask because I changed
the glow plugs on my admittedly aging Peugeot engine at the weekend and noticed a perished pipe. After replacing the pipe I had to prime the fuel line
which was easy with the hand primer but still needed to give it a squeeze when turning the key to get diesel through the pump.
