Engine not starting

[Fihen]

Hi all happy New year to all.
Recently the serpentine belt on my tu5jp4 engine broke and since then I have not been able to get it to start. Engine cranks over but no taco working. I replaced the crankshaft sensor, however, the problem remains engine cranking but won't start. Dashboard readout says economy mode active.
Any advice greatly appreciated

Starting requires motion, fuel and spark. If it is turning over briskly, then it must be fuel or spark. Check you have fuel pressure and spark. If so, suspect the inlet air pressure/temperature sensor, which determines the mixture.

Thanks for your reply. Is the air pressure/temperature sensor a part of the maf???

It does not have a MAF sensor. The full title of the item is inlet air pressure/temperature sensor. By measuring the pressure of the air downstream of the throttle, and its temperature, the mass flow rate of the inlet air is calculated by the engine ECU, so it does the same job as a MAF sensor. It is also known as the Manifold Air Pressure sensor (MAP sensor). Peugeot Part No 1920 AJ.
