Check air filter and replace if necessary also clean or replace Idle Air Control or Mass Air Flow sensor depending on which one your vehicle has. Clean throttle with throttle body cleaner add seafoam fuel injector cleaner to gas tank.


Checked air filter and was clean. Mass air flow sensor was disconnected. The only way it starts is if you spray ether or spray gas into throttle body. Once it starts, it quits once spray runs out. Any other ideas?


Fuel injectors not working you can test injector pulse with a noid light at the injector connector check fuses make sure none are blown and also may have a bad PCM this controls injector pulse.
