05 Matrix. Cranks, won't start. Help! - Toyota Nation Forum : Toyota Car and Truck Forums

Hi everyone. My 2005 Matrix was running fine then simply quit. It cranks and cranks but will not start. There is no sound coming from the fuel pump. When I disconnect the connector at the fuel pump there is on wire that is live all the time (key on or off) and no other wires show power. When I turn the key on it remains the same. No other wire becomes live. I've checked every fuse and relay, no luck. Someone said something about a circuit opening relay but I can't find it. Does anyone know where it is or have any suggestions? Thank you. Dave

Thanks everyone. No CEL's and it was never taken in for the TSB. What I figured out yesterday is the car has to be cranking (not just in the on position) for there to be power to the fuel pump. I pulled the pump as a last resort and bench tested it. The pump is shot. I'm dissapointed in the Matrix breaking down so early (by Toyota standards). My 84, which I bought in 86, was 20 years old before anything went wrong with it. My 91 pickup has over 250,000 miles and aside from the rust it's running like a champ! I'm hoping the non-japanese made vehicles are as good as the ones made here but I'm beginning to wonder..... Thanks again, I'm off ot change the pump
