Engine starts but wont rev up
Here is the general definition.
P0320 FORD Description
Ignition failure sensor is used to check whether the spark ignition
is occurred correctly or not and also used to tachometer drive. The
sensor monitors the voltage difference between a resistance which is on
the battery circuit for ignition coil. When the ignition coil works
properly, the electric current through the resistance is detected as
voltage drop. This is confirmed for every ignition event with the
crankshaft sensor and the camshaft sensor. If Engine Control Module (ECM)
detects a malfunction, no ignition is possible, so the engine would not
start. If there is no ignition signal for a predetermined cycle for one
or two ignition coils, an ignition coil circuit failure exists.
Possible causes
- Faulty Ignition/Distributor engine speed sensor
- Faulty Crankshaft Position sensor
- Ignition/Distributor engine speed sensor harness is open or shorted
- Ignition/Distributor engine speed sensor circuit poor electrical connection
- Low battery charge
- Faulty Engine Control Module (ECM)

SOURCE: wat does code p1400 means
In order to give you accurate information. I need size of engine example 2.0 L 3.0L. but code P1400 means Differential Pressure feedback EGR circuit low input. Maybe your differential oil is low.
