No start

[lout]

please erase codes and see what comes back
a lot of those codes are mismatch
i am not going to waste hours tracking down bogus codes
in post 1 you say when you got car back manifold was loose, back from where?

 

[Baldoldfart]

First off, just tried new crank angle sensor, no change. Can only crank it over by jumping relay pins, not with the starter/key. It gave a couple of kicks like it was going to start then just went back to cranking over.

The manifold was loose when we got the car back from RACV after they looked at it 7 or so months ago.

I thought I had erased codes last time.
Here are codes from today:
U0423-00/IN cyl 1 misfire
P0423-00/N starter relay That could be because I removed the relay to jump pins to get the engine to turn over
U0415-0909/IN throttle position sensor/switch 'B' circuit. Range performance problems
P0500-00/N vehicle speed sensor circuit malfunction
P 629-48/N immobiliser fuel enable signal not received
Trans was:
U0121-00/N, U0100-00/N, can-bus no com with ECM
BCM code 18 and ECU code 18 ECC fault

I tried the starter relay test with the relay back in place, the starter would not engage.

If the timing chains were stretched wouldn't it throw a code indicating that?

 

[Baldoldfart]

And thanks for taking the time to reply, I really appreciate it.

 

[lout]

in my belief timing chains are not measured until engine rpm is over 600
is this a berlina or calais
and i assume v6 auto

it is still looking like it is immobilized
does your car have telematics
has someone fitted a new cluster

I have no idea what telematics are, I don't think the car has had any add stuff added. it was bought new for a company car and we are the second owners. By cluster do you mean new instrument cluster? If so yes it had a second-hand one put in a while ago. Come to think of it that could have been around the time the problems started.

I believe @lout has found your problem?
The cluster?

 

[lout]

still need to know if car has climate control heater
or basic 3 knob type
can your vident reprogram the cluster to match what the car is
can you refit the original cluster

Car has 3 knob heater. I have no idea what the capabilities are of the Vident, I will look it up. just tried to refit original cluster, no lights, no k's or anything. put the replacement cluster back in, all the lights and K's come on, tests Ok but still no start or turn over with the key. The security light flashes and the check engine light is constantly illuminated. It has thrown some more error codes, I'll go and get them.

disconnect battery for 30 minutes
refit cars original cluster
then reconnect battery
then dont worry about lights, just see if car will crank and run
why was cluster changed
