I have replaced the fuel pump and relay switch, no electrical current is getting to the pump when the ignition is switched on, I have checked all the fuses in the cab and in the engine compartment. I dont know where else to look. Note If I connect a power source directly to the pump the car starts and runs. nickwarner Veteran / Moderator Apr 23, 2010, 2:14 PM Post #2 of 4 (1981 views) Re: Mazda MX3 wont start Sign In check the wiring for the control side of the relay. If memory serves there is 12v present all the time and the ECM controls the ground. I may be mistaken, so anyone with direct knowledge or shop manual please chime in on this. If you have the 12v, check continuity between ground terminal and ECM plug. If you have an open then you need to remedy this. jumbojim New User Apr 23, 2010, 2:34 PM Post #3 of 4 (1978 views) Re: Mazda MX3 wont start Sign In Thank you for the advice I will try what you have suggested tomorrow morning.
