Hey can any one help me out, my Speed3 lost all power as i was driving along, all the elctrics are working and it turns over etc.. but no go (its as if the fuel pump died). Its at the mechanics and they said there is fuel going to the injectors (fuel pump is working) but there is no fuel coming through the injectors, they have no idea whats wrong with it. Has any one else had this problem?

Thanks in advance

Pretty rare problem. If you have an after market intake (Cobb,etc) make sure your hose clamp is not rubbing the harness on the battery box. If so it will chew thru the harness and cause all kinds of weird ECU related failures. I can provide a pix if needed. Sounds like the ECU is not triggering the injectors.

1) Possible dead ECU (engine control computer)

2) ECU possibly dropped all programming.

3) broken wire in wiring harness.

I would at least try an ECU reset. Take the + cable off of the battery and leave it off for 15min then re-attach cable and try again.
