Check fuse

Probably because it has restarted from zero and needs to build up mileage to be able to calculate those parameters, just a guess, use it for a while see what happens. By the way, do you have an instruction manual? I couldn't find one?

locate the crank sensor there should be two screws and a electric plug pretty simple if u can locate the sensor

Crank Angle Sensor (CAS) should be replace. Most battery last 48 months,check the date code on top of the battery to see how long it is in service.

try checking all the wiring pugs on the engine particuarly the ones to the crank and knock sensors if you have a managment light on then plug in a code raeder and see what codes are stored

Depends on the age of the car,most common, the motor number is on the edge of the block where its fits to the bell housing of the gearbox/trans. at the front , most of the time you have to clean the edge of dirt or rust to read the number.

you need to have the original ecu and sensor on the engine. you have replaced. if you have changed the ecu put the original one back on as it is paired to the car and only your car. if you want to change the ecu you need to change every box, ecu. immobiliser . alarm. ignition. or you need the pass code for the car so you dont need to do this but this can cost alot.

check the dispack and also check the relays in the fuse box in engine bay. one for fuel pump and injectors. after cranking engine take out a spark plug and see if it has fuel on it if there is fuel then would say there is no spark and it is the dispak. its at the other end of the spark plug leads.
