N/A diesel will not start

[Jayboy]

Went to move the old family heirloom TGD estate today and it turns over fine but no sign of firing. After a quick skeet through the site and the web I tested and eliminated the glow plugs as an issue.

There has been an ongoing issue of poor running and cutting out due to dodgy fuel in the tank and emulsified biodiesel. I have recently fitted new rubber fuel pipes and they are all properly secured but I've also tried rigging up a temporary tank which has worked great previously but hasn't helped today. I also changed the fuel filter knowing it wanted doing anyway but it's still dead.

Determining that the likelihood is that the Stop solenoid is at fault I removed it and took out the plunger as I read that should enable the engine to start. Still nothing.

I ran out of time but will swap the stop solenoid with a known good one tomorrow but is there anything else to look for? Although there has been the issue of poor running, it has never failed to start as soon as the fuel pump is primed - until today.

Please help before I call the scrap man!!

Removing the plunger from the stop solenoid has eliminated that. You may need to bleed it at the injectors if it won't run with normal bleeding. Crack open all 4 injector pipes at the injector end then get someone to crank your engine. Once cranking over each cracked open pipe should start spitting diesel out, once they do, tighten up each pipe in turn and each cylinder should fire up as you close each pipe up until running on all 4.

if this car has the filter with the primmer button on top may be the diaphragm has died in the primmer,

test this by disconnecting the fuel line after the filter and pimp the primmer, if fuel pumps out the primmer should be fine

pimp the primmer,

[Jayboy]

Lol. Thanks guys. Will try again tomorrow. Fingers crossed the weather is okay but high winds, rain and floods are sounding more likely.

If so I'll spend the day in the garage working on the Phase 1 Valver instead

Spray brake cleaner in the air intake whilst cranking to get it going.

pimp the primmer,

whooooops me thinks a case of mixy me toe'sies

Mixed thingies are the way to go, lightens the day wonderfully. Unless we have got it wrong and its about 'pimping ones ride'. I go now.

Well, the afternoon brightened up beautifully today so after a couple of hours finishing off the front subframe removal on the Valver in the garage I went out to look at the TGD.

Started by checking the primer and it pumps fuel of of the outlet just fine. Assumed it would cos it squirts out lovely when bleeding it.

So i tried the injectors. We cranked the engine for a while and nothing. So I tried disconnecting the injection pipe unions at the pump end rather than at the injectors and cranked again. Still nothing!

Disconnected the return pipe from the pump which goes back o the tank and tried the primer button which pushed fuel out of the return.

I just don't get it! Any more pointers? Its a Bosch pump by the way but with the canister filter with the primer button mounted on the inner wing.

Will more persistent cranking help? Or does the fact that even with the union removed at the pump outlets no fuel escaped mean there's an issue with the pump?

[citsncycles]

Not a diesel expert, but it sounds like a pump issue to me, just not sure what exactly

[Geoffrey Gould]

I really dont want to suggest this but is the cam belt still intact? I really do hope it is.
Best of luck.

Is the manual stop lever still spring assisted and in the start position?

[Geoffrey Gould]

ERR. cambelt reaching a bit, really should engage brain before opening mouth. Good shout Defender 110.When priming can you get to the point that pressure building up can be felt?Prime like hell while turning engine over ,anything at the injector pipes?
Think I will stop there before digging an even bigger hole!

Check to all of the above. Cambelt fine, that was one of my first thoughts and manual stop appears to behave as it should. Primer button goes rock hard after a few pumps. Might try jumping it off another car and see if the extra power makes any difference although it cranks well on its own....

Came across a golf forum online last night that had the same symptoms and even though he'd checked the stop solenoid it turned out to be the issue in the end so might have to swap it over and give it a go again.

emulsified biodiesel.

Pump clogged up with the above...?
