blkjdmef8kid Posted January 14, 2008 Share Posted January 14, 2008 whats up just seeing if u guys can answer my question...i just picked up a rex just a sohc d series with a vtec head,and ls obd0 ls ecu...i had a question though...i was driving my car and my crap just died out...happened like 3 times...heres all the things i checked im getting -spark -fuel -fuel pump works -main relay works -compression good but yea now its just cranking and cranking no turnin over in notice my intake air control connector (I.A.c) is not getting enough voltage<---- and also my ecu is shooting a egr and i.a.c code 12 and 10 so could my problem just be -i.a.c connector -fuel filter -distributer bad ? maybe im not getting enough fuel ? or will the ls dohc ecu make me dump 2 much fuel causing flooding ? or is the iac connector just f*cking everything up ? if it is my distributer how can i check if it is bad ? what you think ?

cranny Posted January 15, 2008 Share Posted January 15, 2008 you absolutely should not be running that engine with that ecu. Link to comment Share on other sites More sharing options...
blkjdmef8kid Posted January 15, 2008 Author Share Posted January 15, 2008 you absolutely should not be running that engine with that ecu. why not ? can you explain to me why i can not use that ls ecu? and also will that be the problem its not turning over now ?

cranny Posted January 15, 2008 Share Posted January 15, 2008 cause that ecu is not mapped or designed to run that engine , how is this unclear? what do you expect to gain exactly from running that engine with that ecu? do you know how an ecu work? or an engine for that mater? do you see where im going here? lol Link to comment Share on other sites More sharing options...
lira_s2000 Posted January 15, 2008 Share Posted January 15, 2008 lol theres no need to get angry, just get a p28 (single cam vtec) ecu and chip or tune that one.. and yes that would be my first concern on why the car would not start. Link to comment Share on other sites More sharing options...
