Starting Problem

[resh9999]

Did not start the car many months
. So instal new battery but still cannot start. Upon changing fuel pump, able to start . Its AVS fuel pump. The next morning need to crank numerous times then only can start. Then the car is fine the whole day. Today the same issue. What could be the cause?

are all the ignition parts in good condition? plugs? cables? coil?
if u has a fuel regulator, u can check if starting the engine has fuel pressure or not. if u dont have fuel regu, need to check if the pump is working or not.
if everything mentioned above didnt start your car, u need to swap ecu with other running airtrek. check whether ecu was burned..
