i have a ba xr8 it will turn over but wont fire there is no pats hand flashing, i have checked all the relays and fuses there are no codes except occasionally a can bus error stores itself but nothing shows up at the time of scan i have tested power going to the coil wires one wire is 12v and the other is 1.5 and up to 2 while cranking i have changed crank angle sensor and tested wires one is 1.4 and other is also 1.4 or 1.5 wires also power gets to the ecu plug from coil wires and the crank sensor i suspect the ecu but with no codes coming up all the time i cant be sure has anyone on here had a similar issue or and ideas on what could be causing the issue thanks in advance

also i bought the car with a blown motor and dropped one in all plugs are done up and motor is earthed but have never seen the car run so have no clue of any prior issues with electrics
