Alpina B10 Bi-Turbo: Starting Issue...
First post from me...
I'm trying to get an Alpina B10 Bi-Turbo started, but to no avail. Wondering if I can lean on the knowledge of the forum to help? The car has been parked up since circa. 2015, with the battery disconnected thereafter. When the car was parked up it started and ran just fine.
Here's the current status:
- Same battery as when the car was parked up which has been "fully" charged by trickle charging over a couple of days.
- Fuel tank has circa. 15x - 20x litres of newly added standard UK spec unleaded fuel. Tank was near empty when this fuel was added.
- Vehicle fluids full, but in need of a thorough flush and change.
- Starting attempts made both with and without "jumping" where the car used for jumping is revving at circa. 3000rpm.
- Engine cranks on starter motor.
- Cannot hear fuel pump prime when key is turned to any stage of ignition.
- Fuel pump works (as checked by directly linking a battery up to it).
- Fuel reaches the fuel rail (when fuel pump linked up directly to a battery).
- Key has two brand new batteries in it, but when pressing either button on the key it does not audibly (pings, bongs, clicks, unlocking sounds, etc) or visually (lights flashing, etc) interact with the car at all.
I have yet to check the following:
- Electrical continuity of fuel pump to ignition.
- Spark plug condition and gaping.
- Electrical continuity and working order of ignition system.
- Engine compression.
I suspect there is an immobiliser at play here (key not communicating with car, fuel pump not priming on ignition, etc...), but I cannot find an aftermarket one or anything in the history talking about one being fitted, even as standard? There was what looked to be a remote garage door opener (had a remote in the passenger compartment and there was another white box zip tied into the engine bay near the air filter), but it wasn't wired into the car in anyway and was terrible plastic quality with well corroded insides.
Will continue to do diagnosis, but any steer would be most appreciated in order to lead me to the exact issue sooner rather than later!
Many thanks in advance for any and all contributions offered.
