No, if the ECU is off the old engine, your key will link with the transponder and then the ECU, all good

[AliM]

Also, we used the clutch plates etc that came on the new engine because they looked in good nick. Then attached the gearbox I bought to the new engine and put them both in the car in one go.

Have you used the cam and crank sensors off the old engine? ie. the ones that you know work

[AliM]

hmmmm good question, i'm pretty sure we took absolutely everything we needed off the old engine but i'll double check!

[JohnTurbo]

I've been thinking sensors too. Theres only so many of them that are vital for the thing to run, and the Cam/Crank angle sensors have to be up there. Do all the Z22se appications run idential management?

 

If its actually firing i'd be tempted to see if she runs on carb cleaner. That divides the problem down a lot.

 

My experience of ECU earth issues is the car does less than you've described.

 

It helps to think thusly:-

 

To run an engine needs fuel, compression, a spark and correct timing of events,

You can check 3 of these easily, ie compression tester, pulling the coilpack, carb cleaner/pulling the fuel rail.

(pretty sure any sensors that were in place in the new engine were left in place, we only changed things over that were missing)

[Nelly Vx]

Not sure about the na but the Turdo has two conectors at the back of the block which have the same plugs , I went to one in Oswestry ( orger swapped a engine for a stg 4 Astra ) he had the two mixed up , might be worth a check ;-)

[christhegasman]

So you know the old sensors worked and are not sure about the ones supplied on the replacement engine Job for tomorrow then ? Good luck hope you get it sorted 😃

[AliM]

My scouring of the interwebs tells me (via vocky on z22se site) that the Z22SE only has a crankshaft sensor and it's located behind the starter motor, which we did swap over.  I should be able to see if we've left something on the old engine right?

Lets turn the clock back !!

 

The engine you have fitted was it running ok in the car before it was removed or when you got it ?

 

Has it been stripped down then rebuilt ? 

 

Is it a NA or Turbo ?

 

When you crank it over does it try and start or fire up ?

 

Have tried to squirt petrol in to the throttle body when cranking over? and does it then want to start ?

 

If its been running ok before you fitted the engine to your car then it must be a fuel supply or electrical issue. If its been stripped and rebuilt and there are signs of it wanting to start it may be a timing issue.

New engine Bob, NA. ECU, Transponder and key working pre--swap Spark OK, getting fuel. Sensor gremlins or air/TB issues by the sounds of it. Failing that...Timing?

[smiley]

Anybody nearby with an opcom to verify if the ecu has not lost the key(s) during battery disconnect?

 

[AliM]

Hello VX220BOB, sorry I'll give a quick synopsis because everyone else already knows what i've been up to

 

I killed my VX 2.2 Z22SE engine (it was on 97k anyway and had been on it's way out for a while, i'd been putting off the inevitable), so I bought a donor engine from a breakers and it's come out of a MK4 Astra with 52k on the clock (i've never heard it running, but it's on a 90 day warranty).   This weekend we set about trying to swap the old engine and gearbox for the one's i've bought from the breakers.

 

Everything has connected up fine, put the old ECU on the new engine, checked all the earth wires, all the relays.  It wants to start, the fuel pump and injectors are working, it has spark.  It just turns over but won't start.  We think it's an electrical issue somewhere, sensor or earth, but we can't pin point it

 

I wouldn't know how to squirt petrol into the TB while trying to crank it, but i'll find someone who does!

Could the immobiliser/transponder have buggered up somehow?

 

Its just that the symptoms sound very similar to the problems we had with stuwys engine swap (immobiliser not recognising the key).

 

I hope you get it sorted soon Ali

Cheers bud, fingers crossed. How did you sort Stuwys out in that case?

[VX220BOB]

I am guessing that both engines are identical ?

 

Has the throttle body sensor of your old engine been swopped over ? if not and you say its trying to start then could it be a calibration issue with your foot throttle sensor  Vs  the new engines TB sensor !!

 

Has all the sensors off you old engine been transferred  to your new engine ? and are they the same type ?

Stuwy had to change the ECU, ring, and key transponders.

 

Shouldn't be the case with you as you havent changed your ECU. If someone near you has an opcom they can check that all 3 are talking to each other properly, or if you need to recode your keys (which can be done with the opcom if you've got the code somewhere)

[AliM]

The only obvious thing i can find on the old engine which we didn't swap over is the plug you can see at the front of this picture, which is connected to the block just to the left of the oil filter housing.

Pretty sure thats just an antiknock sensor and shoud no affect anything.

swap the coil packs over
