Hello i have been having a problem with my 04 corolla. Car will crank but not start. I tried removing the alarm but still wont start. Engine will turn to start but no ignition. This has happened a few time and some times i fixed it by removing an reinstalling a relay. But i replaced it this time and still wont start. What should i look for? I had a friend come by and he says its either the crank sensor or ecm. Not sure tho. Any help on this is appreciated.
