Im tearing my hair out with this car. It is a 2000 civic si (b16a2) that has ran fine with no problems. I parked it one day and and the next morning the motor would trun over but not start up. I checked for spark( getting good hot spark) has fuel pressure, voltage to the injectors. I also checked the timing and it is right. so far I have replaced the distributor with a brand new one, checked every fuse, tried a different ecu, new main relay, checked all the grounds and triple checked the plug wire order. nothing seems to work. I have searched the forum and still havent found a solution. Please help!!

 

Does the engine start and run with starter fluid?

 

try puting ground wire every wer and cheek fuses or has ur heater core ever went out cuzz if so its known to fry ur ecu

 

Might Not Help But You could check for Compression in the cylinders?

 

Tried cranking woth starting fluid, still nothing. heater core is all good. gonna try cleaning up my grounds. as soon as i get a guage I will post compression specs

 

Timing belt probably
