Just changed the diesel filter on the Astra and now the bastarding thing won't start It did start at 1st but as soon as I rev'd it, it would die. Now it won't start at all. Took the line of injector 1 and no fuel squirted out.

Whats happened , theres no fuel leaks, checked for any wires that I maybe knocked off but theres nothing

The fuel filter will be empty.

Pour diesel straight into the filter.

Tried that. Put the old filter back on too to see if maybe there was a fault with the new one but still no joy.

If you upped the fuelling & boost previously, may I suggest it could have something to do with that?!

Is there a primer on it? like a small rubber pump in the engine bay?

If not, keep filling the filter up with diesel, make sure you have all the rubber seals in the correct place, and wind it over with the throttle to the floor.

It will eventually start

maybe the injector might have some dirt in there when you took the old filter out?

when i changed the diesel filter on the audi i bought i got told to turn the key on and off a few times before i started it, i did that and it started fine but that was an 06 reg so might be different on your car. it did run rough untill more fuel got in and it was fine after that

Spray brake cleaner into the intake to get it running, you will have created an air lock in the fuel system now.

No self primer on it, checked all the seals over, I guess I'll just have to keep filling the filter then and hopefully that will work.

Rich upping the boost and fueling won't have caused it. Worked fine until I changed fuel filter then it died.

Have you replaced the copper washers on the feed union? if you have left one washer off it wont run as it sucks air instead of Diesel i had this on my old one.

Just an airlock in the fuel system, just needs turning over until the filter fills up then crack off the injector furthest away from the filter and bleed it, just don't forget to tighten it up.

My combo did exactly the same when I changed mine Jamie. I brimmed the filter then filled the out pipe that comes off the filter with filtered diesel. Then a shit load of easy start and I finally got it going after having to jump it because it flattened the battery

I spent ages filling up the filter, trying to bleed it via the injectors and bleed screws and didn't get any fuel at all. Must have spent at least 2 hours trying to do it that way.

In the end my mate suggested we tow it up the road in 3rd gear, so tried that sorted it for me.

Bloody nightmare, I thought changing a fuel filter was a 10 minute job

It is but you just have to remember and fill the fuel filter with diesel first, or if it has a priming pump do this and leave one of the pipes off until you get diesel coming out the top of the filter and then try for a start.
Or if its a newer car that primes when you turn on the ignition then do this a few times
