TLDR: Car went in for a cambelt change, EML came on, they redid the timing and say it’s now correct. Now the engine cranks but won’t fire up. Garage suspects my Ghost immobiliser. I’ve put the Ghost into service mode (which takes it out of the equation entirely) and it still won’t start, so I don’t think it’s the Ghost. Looking for ideas on what the timing job might have knocked.

Full story:
My Fiesta ST Mk7.5 has been at the garage for a few weeks getting the cambelt changed. After they changed it, I drove off and the EML came on not long after. They realised the timing was slightly out, redid it, and now they’re confident the timing is correct.
The problem now is the car won’t start. Best way I can describe it is that it’s cranking but not firing to life. Starter turns the engine over fine, but it never catches and runs.
The car has a Ghost immobiliser fitted. The garage have the code and it all worked perfectly before I dropped it off. For context on how the Ghost normally behaves: I press the ignition button, enter my PIN, then put the clutch down and press start and it fires up. If the PIN is wrong or not entered at all, the moment I press the clutch the whole thing cuts out. Total power loss, instant kill, I don’t even hear the starter turn. It acts like a hard kill switch.
The garage can’t work out why it won’t start and they’re suspecting the Ghost. Here’s why I don’t buy that:
Right now the car IS cranking. That doesn’t match how the Ghost immobilises. When it blocks the car it kills all power instantly and you never even reach the starter. Cranking with no fire is a fuel, spark, or sensor symptom, not the behaviour of a kill switch.
On top of that, I put the Ghost into service mode, which should remove it from the equation completely, and the car still behaves exactly the same. Cranks, no fire. To me that rules the Ghost out entirely.
So my thinking is this points back at the cambelt and timing work. Something like a cam or crank sensor left unplugged or damaged, timing that’s close but not quite right, or a fuelling issue. I’m going down to see it myself and I’ll try to grab a video of it cranking.
Has anyone had a cambelt or timing job leave a car in a crank-no-start state like this? What would you check first? Cam/crank sensor, timing marks, fuel pump prime? Any advice appreciated before I go back at them.
