Engine Swap

[Galaxy newbie]

hi guys need some advice from the more experienced Have removed my old engine from my galaxy ( engine code 1z) and have fitted with a second hand engine (AHU) but have kept original ecu but diesel pump is from the new engine. Trouble is car is turning over but not attempting to start. Diesel pump is drawing fuel from tank but not sending out to the injectors. Would this be because the diesel pumps are coded and so it's an immobilized problem, not to sure how the galaxies work. ANY information you can give would be much appreciated. Thanks.

hi

by memory the pump isnt coded, check for supply at the cut off valve on pump, if not take off the wire off and put a supply on it then try to start it up, when you turn key check see what door led is doing

Would that be the fuel cut off solenoid. We checked for voltage there and was all ok, I was wondering if it could be that I haven't bled the diesel pump properly. I bought a hand pump and connected to the return pipe on the pump but when I pump it the ball doesn't reinflate as if something is stopping it. I also tried cracking the nuts that bolt the rigid lines to the injectors and cranking but no fuel. It wouldn't be because I haven't used the ecu from the new engine would it?

You should have your hand primer pump connected to the supply from the tank not the return pipe, in other words remove the pipe from the tank on the fuel filter connect that pipe to the inlet on your primer then the outlet of primer onto filter then pump away.

Ok will try that next and report back, grr flaming Haynes manuals lol.

Just out of intrest, if I place the hand primer in line after the fuel filter and pump Manually how do I get the air out of the system. Do I then crack the injector pipes open and wait for fuel to reach them by pumping manually and the air will escape that way. Sorry for being thick.

[chrispb123456]

Any air will be returned to the tank through existing pipework, once you done that it should only be neccessary to crack open one or two injector pipes, crank engine and watch for fuel being ejected from loosened pipes.

 

Fuel will only come out injector pipes while cranking engine.

Thanks so much for the reply chris, that's cleared things up for me was gonna try it today but wife went into suspected labour. Will let you know the result with the galaxy as soon as I get a chance to look at it again

Have recharged battery attach primer pump between fuel filter and pump inline and now bleeding lovely. Have open injectors and turned engine over several times in 5 second bursts and still no fuel to injectors. I assume it should spray fuel all over the engine in a fine mist, so you would know it's working. What next can anyone tell me if diesel pump is coded as was thinking of trying to bypass the immobiser. Anyone else got any ideas?

[Galaxy newbie]

When turning engine over with no 4 fuel line to injector undone am getting something through I think as rocker cover has splashes of diesel over it but I just assumed there would be quite alot on engine. By no 4 injector I mean furthest from the diesel pump.

I do beleive you only get 12 volt to the stop solenoid for about 2 or 3 seconds, try disconnecting original wire and do a temporary one straight from battery, listen for the solenoid click when you put 12 volts to it.

[zorgman]

thats correct its only there for a few seconds then goes off only comes back on when engines turning over works as a safety thingymebob (thats where i take my feed off for led running lights)when you crack open a injector dont expect a spray of fuel as that only happens at nozzle tho you should get fuel coming out. Have checked and pump is not coded to ecu so do what i first said and take wire off cut off valve and give it a 12v supply direct to try that, could also be the actual valve itself may be worth taking it out to check.

Ok, when I first put keys in ignition and turn to light dashboard immobiliser light on door is coming on for maybe 2 secs then going off, I assume this Is right. No flashing from door pin as engine is being turned so I'm assuming this is correct also. Got fuel coming out from injector rigid pipes, and stop valve is working as checked voltage and can also hear it click when I first turn key, but STILL not starting, it's made a noise like it's trying to start very briefly on a couple of occasions but still nothing. Also after cranking from key for a few seconds I can still see air in the clear pipe running to diesel pump( albeit only medium sized ones) so do u think it's drawing in air from a pipe when I start cranking from the key. HELP ( by the way wife and I just had our little girl, got home this afternoon :-) )

Cant really help but congrats on the litte un!

Air bubbles in the line up to the pump is normal I think....I always used to see them in my old Sharan.

Just to add am getting spray over rocker covet from injector pipes but it's still looking a bit bubbly on the top of injector inlets where pipe connects.

[Galaxy newbie]

She's running I ran a direct live feed from battery to the fuel cut off solenoid and it started first time. So now I need some advice on how to fix it so it works as it should do. As I assume a direct feed permanently isn't good what's best thing to do guys.

Checked voltage coming from loom down to the plug end that connects to the diesel pump plug and there's zero voltage so short of cutting it out back through loom I don't know the best way to sort it out. Any advice
