Do I need to do anything special when fitting a new diesel lift pump?

Good question: thanks for asking!

The new lift pump was installed without problem, but the engine still doesn't run.

I took the injection pump off last week, and I've just had a call from Colchester Injection to tell me that it was rather gunged up with jelly-like fuel (not bug, they reckon, but just what happens when diesel sits around for a while: that begs other questions, but they can wait for now).

Fingers are crossed (a constant way of life for my fingeres over the last few weeks) that this overhaul will get the engine running again.

There is a danger that your exhaust is now filled with water after all this cranking!

No, no ...... please do try to pay attention at the back there.

I told you weeks ago that I only turn on the raw water intake seacocks once the engines have fired!

But a very worthy reminder .... thank you! :cool: ✌
 
Can I draw your attention to my post elsewhere about the basic rule on these forum’s that regarding not reading all the previous posts ?

Did you ever find out your problem. I have the same non starting issues. I fitted a new lift pump and had the injector pump rebuilt but still cannot get it to fire. Sick to death of bleeding but no difference.

Apologies to the forum, for not finishing this story (I got sidetracked by life issues), and thanks to heffkid for the reminder.

It's, sadly, not a denouement that will be of great help to heffkid: I fitted the overhauled injection pump, bled the system (again), turned the key, and .......... the engine instantly sprang into vigorous life.

So it seems the injection pump was blocked by diesel jelly (not diesel bug), even though it had been running fine just a few days before.

Anyway, thanks for all the contributions, and I'll follow heffkid's thread with interest (edit: I don't think he's got another engine thread: but, heffkid, I strongly recommend that you start one. As you've seen, there's lots of very knowledgeable, very helpful, people on this forum. Good luck!).

Right ..... I'm just off to see if I can start the 1987 VP2003, in our Falcon, that hasn't run for well over a year now: fingers crossed, please!

well diesels are quite simple to work with. check fuel is flowing from Tank. then check its flowing from filter housing. then check its coming out lift pump when pumped . then loosen a bleed screw on injector pump and pump lift pump till diesel comes out.. then loosen an injector and try and start the engine. if she starts just tighten injector. A tap with a hard object on injector pump can help with stuck valves.

I fitted an outboard motor type fuel priming bulb between the tank and the primary filter to help bleeding after filter changes . It works a treat ,way better than using the priming lever on the lift pump.
