I am having problems starting my peugeot 106, it turns over but won't fire up. I have had a new crankshaft sensor, coil pack and ignition switch, can anyone help please..

. Check for spark. Since it sounds like you have no spark, check "key sensor" reference voltages. If they are way low, the ECM is likely bad. I like what you have focused on so far--the ECM is the next step in the progression.

. Check for fuel.
