Nissan Primera P12 engine replacement help

pherbert

Hi guys i hope someone can help or point me in the right direction before i set light to the car....

My dad has a Primera 2.2 which originally had a YD22DDT engine in it. the timing chain snapped and he took it into his local garage who sourced second hand engine and said they'd fit it for him.
He paid them £1200 in total then told him to collect the car and it had an injector/nats problem and wouldn't start

He then took it to nissan who said it didn't but as they didn't do the work they wouldn't investigate it so he towed it home and its sat there for a few month and brought a cheap car to use.

So im now trying to sort it out for him, im handy-ish with cars.

on looking at the car, it cranks but just isn't firing (sound like its not getting fuel, fuel is being pumped around tho) the engine they have put in it is a YD22DDTI so i'd say that's the cause of the problem.

The original garage doesn't want to know anything about it saying they just fitted the engine my dad got (which they found and he just paid for it) they said the engine came with no fuel pump etc so the other parts in the car are the original parts except the engine.

Is there anyway of getting this to work without replacing the engine with a YD22DDT??? looking at it from a novice point of view, it seems to me that the fuel pressure or something is wrong if i put a fuel pump from a YD22DDTI in it would it work???

Thanks in advance for any help or light you could shine on it for me

The new engine is commonrail and the old one was direct injection.

Fuel pump systems would be different, ecu is deffo different! The new engine should have an intercooler whereas the old didnt AFAIK.

Bad form of the garage to not spot these, easy to see differences!

It would be possible to get it working with more parts and time, but easier option is to get the right engine IMHO.

Thanks for the reply Alan,
yeah really bad form from the garage. New engine not an option really he'd scrap it as wouldn't put that much more money into it.
I was think of changing the fuel pump but didn't know of just doing that would work. don't know if the ecu would need remapping or not?

Its more a case of replacing the ECU with one for a commonrail. Then you might have problems with Keys/Nats. Not sure on that though.

Where you based?

Oh...Bit far for direct help so!


Bring it back to where the work was done. It was left there to be fixed, its not!
Simples!
Stand your ground, threaten small claims or similar if needs be even!

Or find a Nissan mechanic that might take it on as a nixxer if you didnt want to go back to the original garage?

OP, if that garage sourced that engine to your dads car and told him it would work, then they are responsible for getting it going. On the face of it, it may be the case that they wont be able to if the engine is incompatible with the rest of the car. And if I am right here, I would be asking them for a refund. In my opinion, they were negligent in recommending and fitting the engine they did. They also have a cheek demanding payment for a car that leaves their premises no more operational than when it arrived.

The problem with all of the modern stuff is that things like HP pumps, injectors, and even EGR valves are programmed to the ECU which will run and control them. Even if they fitted an identical engine to the original, chances are that all of the aforementioned bits will need to be swapped across from the original engine.

I think your father's best bet to have got that car operational would have been to repair the original engine. That probably is now no longer an option.

they even dumped the old engine now as well.... i tried the garage and they are having none of it, there argument was it was got from a 3rd party uncheck and was paid directly to the scrap yard...

I was hoping a nissan mechanic might be on boards wanting a private job if it can be fixed or at least knowing its a waste of time and move on and forget he ever owned it

If you were closer id help more. Dig in, as i said..small claims!

pherbert

i already said that to him, he doesn't seem to keen on doing it tho, he'd prefer to forget about it... i wouldn't of paid them in the first place but there you go

that engine has sensorss on the engine basicly witch are coded to the original ecu ect so basicly the nats or nissan anti teft system wont pump the fuel because its imobilised.get the ecu off the new engine basicly is your answer

pherbert

thanks for the reply muckey...

got a reply on another forum to replace camshaft sensor, injectors, dual mass flywheel and fuel pump off the di engine and it should work......

can anyone confirm this? reason being the old engine is gone now so would be buying theses part???

That seems to be worth a go. The garage should have known this I think.

Wow wow wow am so amazed by everyone’s contribution and am facing the same problem at the moment I bought a new engine but I realized it had some differences.

I was so keen because I have my old engine working but the turbo is bad so I decided to buy a new complete engine, but after fixing the engine in the car, the car couldn’t start, when I brought the new engine I tried to show the mechanic the different but he kept saying that the engines are the same.

after we check the nozzles it shows they’re pumping fuel to the engine but the engine won’t start still.

one mechanic told us to replace the old flywheel with the one on the new engine and the engine will start, reasons that the sense of key doesn’t correspond with that sensor of the new flywheel so for that reason we need to replace the old one back to the new engine.

I just want to know which other parts that has the old sensor might need to be replaced?

thanks for your help.
