Was driving my 01 Tacoma V6 the other day and it just shut off. I pulled over and tried to restart it. It will turns over but want even try to fire up. I hooked my scanner up and it will not even communicate with the ECM anymore. Checked the power to the coils and the injector, I have 12V feeding them but no spark and no fuel. I tested the cam sensor, MAFS, relays and fuses, all are reading as the book calls for. I did not test the crank sensor!! I checked the timing belt and all's well with it. So I thought it's got to be the ECM, so I purchase one and low and behold I still have the same issues. Looking for some help from all of you out there. Any thoughts before I throw in the towel and send it to a shop?? Could it be an issue with the igniter? I don't even hear the fuel pump come on and off, I even took the fuel rail crossover off and turn the key to on and no fuel came out. Thanks for any help!
