im having trouble starting my car. 94 integra gsr, jdm type r motor. never had a prob before. when i start it, it fires up no problem at all but as soon as i let go of the key for it to fall on the on position it shuts off. i have to do this numerous times i usually have to hold it crank over for like 5 secs before i let the key go for it to start. i reset the ecu and this problem seemed to go away for a few days but its back and keeps coming back. any ideas would be appreciated. new starter in it by the way. never had any problems before and when driving runs like a champ

 

Pretty common problem.
