so i killed my car about a month ago pulling into the garage, and tried to start it up again but no go. the car cranks like it wants to start but no juice. i checked the power to the fuel pump and there wasent any, so i figured maybe crank sensor went bad. i did a little looking and found that if i was getting spark that shouldnt be the case, and im getting spark. so i replaced the main mfi relay, and the resistors on the fire wall and still nothing. so im thinking maybe the immobilizer did something funny but i cant get into it with ecuflash to shut it off. any ideas how to get into my ecu, or anyother ideas why im not getting any power to the fuel pump or injectors.

 

Fuel pump only gets power when cranking. Are you checking power at the pump while someone is cranking the engine?


Power to injectors is likely a fuse or other wiring issue, the injectors should always have power when the key is on, the ECU only controls the ground.

 

Did you do a good visual check of all the fuses?

 

I'll check when cranking and I pulled each fuse and checked them. Thanks for the ideas I also tested each relay
