Non starter

[damonleslie]

I am having trouble starting the engine (bmc 1.5) after replacing perished fuel hoses.

 

I have bled the system several times but no luck at getting it started.

 

Could it be that I still have air in the system?

 

Also I think a new set of glow plugs are due.

 

Any advice is greatly appreciated

Fuel in tank?

Tap turned on?

Bled the filter on the top?

Have you bled all the bleed screws on the pump?

Any white smoke when cranking?

Disconnect a couple of injectors and crank. Any fuel spirting out? 

Check heater plugs by measuring current when heating, with clamp ammeter, should be about 40 amps if they are all OK.

Kept bleeding the pump for at least 30 seconds after you think all the air is out?

I have around 8 gallons which measures just over 6 inches. 

Fuel is coming through.

 

First I bled the banjo on top of the filter (once fuel came through I continued for 30 seconds).

 

Then the bleed screw on the pump (on the left above the nameplate).

 

Then I undid 2 of the injector pipes and cranked it. Small spurts come through.

 

Then turn it over (full throttle) and a couple of times it sounds like it want to start and then it just turns over but doesn't fire up.

 

I have had white smoke when it tries to start but then nothing.

 

I am unsure how to test the glow plugs.

Almost certainly air in the system. Either a bubble has moved from the pipework or you really are out of fuel despite the 6" in the tank. Start at the filter and bleed again but this time pump for at least 30 seconds longer on the pump bleed screw.

 

If it were a glowplug fault you woudl be likely to still get exhaust smoke but as the smoke seems to have gone away that shouts no fuel in being injected.

 

I trust the start bate try is well enough charged.

There is more than one bleed nipple on the 1.5D rotary injection pump, you have to bleed all. Do you have the manual? Tony has it.

Just crack (not undo) the nuts at the injector end of all 4 pipes and crank the engine until bubble free fuel is coming out of at least two of them. If you can reach (or have an assistant), you can even nip up the injector nut once bubble free, while continuing to crank, and the engine should fire.
