Had an alarm recently installed. Bypassed the clutch and have got an immobiliser bypass aswell. When trying to remote start, ignition will turn on, but car will not crank or go any further then ignition. What could be the problem? Is there a way of narrowing down the problem?

 

There are two starter wires, both of them need to be energized.

There are several things that could be wrong.

The clutch interface could be wrong. To test this, manually push the clutch down and try to start the car.

The immobilizer bypass could be wrong. To test this, disconnect the 'ring' on the bypass and insert a key in the ignition (but don't turn it). Then, try and remote start it.

The starter interface could be wrong. To test this, with the ring still disconnected, put the key in the ignition, remote start the car, and when you hear the relays click for the starter output manually crank the car.

 

The turbo timer function doesn't work either. So could it still be that there is another starter wire not energized? Or does that just effect starting. I've tried the clutch thing, it's not that, i'll have to pull it apart on weekend to try the immobilizer options.

Thankyou soo much for your help KPierson. It sucks when you take your car to a "professional" installer with "10 years" experience, fork out hundreds of dollars and then come back with a half functioning alarm.

 

If the turbo timer feature doesn't work (and you are engaging it) then that would narrow it down to either an ignition wire or a tach signal.

However, neither should keep the car from cranking.
