so i was driving home normally on friday night and just before i pull into the drive way, the engine shuts off but i still have electrical power (radio is still on, all lights are still on)...so i try to restart the car and it makes it's normal starting noise but the engine doesn't turn on. after trying a couple times i decide to give up and try in the morning. the following morning i started the car and it started but the engine shutoff again after 5-10 seconds. again, i tried restarting but still the engine won't turn on but again i still do have electrical power...i also check all the IC piping and it was intact...so i replaced the spark plugs with some denso ones, replaced the alternator with an sc300 one, i have a new optima battery, and a fairly new 2jz starter and yet the car still won't start. I have a 1jz with stock twins...so now i don't know what else it could be...could be a faulty fuel pump?/ecu?...any info would help a lot!
