Default 850R immobiliser removal

Hi all
This is my first post here.I have a 96 850R that has just had an engine change and now the immobiliser has prevented starting. I don't have the remote for it, just 2 keys. Is there any way to bypass or remove the immobiliser? I've tried cycling the doors and ignition. No good. There are no fault codes that come up. I'veswapped all ignition components from a runner just in case but no go.
Thanks

I doubt that is your problem.

If your hazard light are flashing and it will not crank you can bypass the immobilizer.

Locate relay 210/211 in the lower central electrical unit which is on the inside firewall, just below the fuse box. Remove relay 210/211 and then look at the bottom of the 210 side and locate pins 50e and 50f - they are in the center of that side of the relay. Fashion a jumper wire and jumper the socket positions associated with those two pins. It should start and run fine if that is the problem.

Volvo makes a bypass relay that actually has the jumper wire in a plug in case for the 210 side. I can look up a part number for it if you would like to permanently disable it.

It cranks over but no spark. I've checked for power to the coil today and there is when the ignition is switched on. Anything engine related I have changed. Cam, crank, water temp, coil, airflow etc. This is the first time I have had a problem with an engine change. I have 3 t-5's also and 2 had the engine replaced with no dramas.

Could it be the ecu? Bloody thing drove into the workshop before the change!! It had a blown head gasket so I put a new motor in it.

If it was the Immoblizer the motor would not crank.

Is the Cam sensor wiring good?

Is there any codes stored?

Yes they are. I put the ecu in to the other car and it started so rules that out. I put it back in and P0120 came up which did not before. I cleared it but came back again after cranking. I changed the TPS and checked the wiring. Had 0, 5.1 and 5.8V across the 3 wires to the TPS.I have been told that it should only have one 5V supply from the ecu. What do you think? I've checked the loom and there seems to be no damage etc.

Did you use your flywheel of the one that came with the motor?

Sounds like cam or flywheel sensor signal is missing somehow.
