Hi everyone. im new to the site and had some questions. ive been workin on hondas for a little while. I just finnished swappin a d15 1.5 vtec motor into my 92 hatch. when i try to start the motor cranks but wont start. now a couple of times i managed to start it but it runs really rough and dies. now i know im getting air, fuel and spark. i dont know where else to go i checked all sensors, fuses and grounds and im stummped. someone please help me.

 

are you throwing any codes/CELs? more info is needed. Did you use the correct ECU etc.

 

one thing your could think about is checking timing also. and we do need more info.

 

its not throwing any codes. i got the p28 hoocked up to it. i changed spark plugs, distrib cap, wires.

 

u mean ignition timing. i thought u need the motor to be running to check that.

 

he means your timing belt. maybe your off a tooth or two.

 

how do i check if it jumped a tooth?
