Update
Changed the cps, no joy.
Rechecked the pump output after the filter head with just turning the ignition. On, 200ml about Decided to remove filter and check output 200 ml so filter OK I assume. Screwed filter back on. Watched the clear pipe as a mate turned it over. Hey presto slackened injector pipes squirting. Did them up she fired straight up! Bear in mind previously I'd bled to the filter head, bled to the pump with a hand bulb primer, slackened all injectors, flattened four batteries and still no injection. She starts cold great, warm the best I've ever known and idles like a purri g kitten. Weird I know
All I have to do now is to get the injector light to stop it flashing when I blip the throttle to 1500 then release, she drops back, almost stalls light flashes then idles. If I rev above 2000 release it doesn't happen

My project car does that but only when the engine is cold. Wammers would know but i suspect a problem with the fuel quantity servo in the FIP, it had been run on veggie oil before I got it. No fault logged though. Upping the idle revs a little helped.
 
Nrv should be after the filter before FIP as far as I'm aware. Mine is fitted in the clear pipe.
(There is a pic of it on the page you mentioned startermotor/WDYDWYRRT thread)
Wammers has lift pump check in tech section, just unplug your NRv and test from there

I'm so lucky have you watching my back. So mine is a waste of time gumming everything up :eek::p:D:cool:

I'm gonna have to go through the receipts see if I can see who put this in :D ...
I hope it's LR :p - Im not sure if that's bad of me or not?

She will have bit more in her again once I get this out ;):)
 
Nanocom says timing modulation is 48. The injector light flashes when I rev to 2000, it flashes on the return. If I rev to over 3000 it falls back OK and no flashing injector light. Oh forgot to say it has a rock solid idle of 750 at warm idle. Nanacom records major fault intermittent, I guess that means the flashing injector light .Actually records fuel flow value out of range. I can't see any air in the clear pipe. Starts super hot or cold.
She's done 165,000 miles, automatic.
Is it possibly the injectors, mind you there's no smoke . Thinking of tryi g this forte stuff.
Any suggestions, gratefully received. Oh new filter fitted as well, pump tank output reasonable at 180 ml
Thanks
 
You are winning as it is running now, i wouldn't have thought injectors would fail, unless no4 sensor? Injector cleaner won't hurt

Are the nanocom readings same as page1 as Wammers said what that means...did you check wiring seems decent on Cps/inj4?

The "fuel flow value out of range" is present on every P38 I've looked at with Faultmate, I think it's a bug in the diagnostics.

I have never had that with my Nanocom on any P38 it has been used on. His problem is highly likely to be one of the quantity servo wipers momentarily losing contact with it's track.

So that's a fip change?

Normally you will see Mil lamp start to flick on when coming out of cruise control. Then eventually engine will start to stall at low speeds when coming up to lights or applying steering load at low speed. That is when you need a new pump.

You had it :D


I've heard of some adding sulphur to their fuel to try and give FIP a little more life, no idea if it works and would depend on the particular problem?

Diesel Jones in Mancland is apparently the go-to FIP guy

Diesel Jones is where I got my refurbed pump from. Not a bad job with the right tools.

As for adding sulphur, well, maybe. Probably pay more in additive than a new pump by the time it fails. Mine lasted about 140k miles which isn't too bad really.
 
Don't say that! - im on 142,000 :eek:

I'm dreading FIP only matter of time. I will probably make myself do chains at same time so I may inadvertently kill it at that point :(
I'm learning more and more so hopefully by then I will be competent enough
