Project Tractor engine swap

So it's now running fine?

Trust me, if it was running right, this forum would be under no doubt about it.

Its 'running' like a bag of shite - a bugger to start, clattery, smokes like a steam train, stalls a lot, lumpy idle, slow to build up revs....  ...need i go on?

Torch it

[CaptainZok]

Couldn't be something stupid like a leaking fuel delivery pipe could it?
Thinking a leaky pipe/union could be letting the pump draw air along with the fuel and give simptoms of the pump requiring bleeding.
Or I could just be talking crap again.

now getting code 34 (no rather eml though - thats why beemer owners think their heap of crap is so reliable, it never brings on warning light)

34 - injector timing out of range

bugger.

[familyman]

You could try a can of clean fresh deisel support it above the engine for gravity feed and plumb in using rubber/plastic hoses to the pump intake pipe from the filter to the pump. If it runs okay youv'e got a fuel delivery prob. if still the same pump onwards. Have know filter housing itself to cause problems even though bled out and full of fuel:)

Ah chance anyone can pm wiring diagram for early and late pumps/starting system just to have a butchers, cheers

Does that mean the ecu may be different for the two engines or could it be a different sw version is needed?

only wiring diag i have is haynes.


so the error code, know what that means?

hooray!!! that concurs with the running problems!!!! simply put the injectors are putting to much fuel in amd the ecu cant back it off!!!  got to be pump sensor, or pieco lead injector!!!

[familyman]

Only time i've seen this is when pump timing solenoid failed on the bottom of pump, but when i got full story was due to pump/engine being churned over for hours without any deisel so cam shoe roller in pump had broken up leaving metal particles in fuel as evidence. But i digress, If your sure And no offence meant that engine was okay before and you haven't removed pump then basic pump timing okay. Advance and retard on pump controlled by ecu/software taken from MAP or MAF and temp sensor readings. So either your current sw as CaptainZok says is wrong, could try loading earlier software or pump is not compatible due to different internal make up ie maybe no timing solenoid. Are part no's for ecu the same for original system and donor engine. If the same internal board and pin no's for inputs/outputs the same just a software programming issue.

JUst a thought crossed my mind ( i know a very short journey )  Does your  system use a water temp controlled cable to advance/retard pump for cold start. Old and basic but it works. If so is cable adjusted on pump correctly and does lever on pump move okay.   As i said this is old school and would be suprised if your beemer engine has it

The ECU is different, hence why I had to swap over loom.  My one had MAF etc, not present on earlier one.  The software is not flash updatable.

The guy said the engine was running fine 'with a small amount of top end noise' about a month ago when the gearbox failed.

Omegatoy had heard the engine running previous to that.

The piezo electrical connector on on eof the injectors had a different plug, so I modified to fit. Could these be different?

The ECU gets coolant temp from a electrical coolant sensor in head, alongside the dash one.

Is there a sensor in the pump then?

TIS mentiones something about a needle valve, but no details...

If yous is a late car with earlier engine the new loom off of older car should have had same injector plug, or did you fit your later injectors to engine, if so you'll need to go back and fit original injectors. As this sensor looks for flow through the injector. Try this first. Again i wouldn't mess with pump if all was okay.

Mine is a later car with earlier engine. I currently have the later loom and ecu.  Pump and injectors are earlier ones (though look the same, except for the plug on the injector with the electrical plug).

injector pump timing solenoid, usually on the bottom of the pump with 2 black wires on it and 2 torqs screws holding it in., if this is the earlier one then it may not be compatible with the later management, equally the centre injector with the wire on may be to different values, it has to be one of them

[Omegatoy]

damn in the time it took me to type on this damn laptop there were two replys!! reckon familyman has a good slant on thing!!!

You think changing them over may make a difference?  I am not convinced, but will bow to you greater knowledge  :-/
