tommy51 Posted January 12, 2006 Share Posted January 12, 2006 hello there. i am brand new to this site. i am an auto technician in kansas city and was suggested to this site from an online technical forum. i have a 93 legacy that starts runs for about 3 seconds and then dies if you try to keep it running with throttle it backfires severely to the point that it has broken the housing of the maf sensor. this is what i know so far. when it stalls it has fuel pressure fuel injector pulse and spark. maf sensor makes no difference connected or not. and the timing belt is aligned properly and i have no codes. thanks for all who take the time to read this and if anyone has some good input or ideas i would greatly appretiate it.

Legacy777 Posted January 12, 2006 Share Posted January 12, 2006 If the MAF sensor housing is cracked, I'd seriously wonder if it's working correctly. Have you checked to make sure the timing is correct? You may want to verify that the timing marks on the crank sprocket & cam gears align with the corresponding marks. Not sure if you have a factory manual, if not this should help http://www.main.experiencetherave.com:8080/subaru_manual_scans/1992_FSM_(Engine_%26_Electrical)/ Also, I'd recommend checking out www.bbs.legacycentral.org too.

beezer Posted January 13, 2006 Share Posted January 13, 2006 Did you check to see if there is voltage to the MAF? The car will start with the MAF disconnected, but will only run for about 3 seconds. Seems to me that is probably the place to look. Good Luck Beezer Quote Link to comment Share on other sites More sharing options...
