Ka24de will not start! Cranks but wont fire

[sasmar929]

Okay, so swapped in a 93 ka24de and manual swapped my 89 auto. My ecu is #26, only sensor not plugged is knock sensor, and some brown plug by back exhaust side of motor. But i dont have anything for it to plug to. My car does turn over, but it will not fire.. We've checked timing like 6 times, 3 sets of plugs, firing order is right. (de) is supposed to be 20degrees before TDC. Getting spark.. Its almost like it will flood or something.

So... What will cause it to flood or send TO much fuel? Any other ideas on what could be wrong?

why dont you try plugging in the knock sensor

Brown plug is your o2 sensor I believe

agreed. that can give it a false reading and dump fuel in. but then again i dont know anything about ka's

im not familiar with the numbers on ecu's, but if the ecu is from your sohc u need a s13 obd1 ecu. sohc ecu wont work.

assume u also change to a DOHC engine harness? you need the knock sensor plugged in. the brown plug (if on the back of the head near the firewall) is for a VAC switch, if you dont have butterfly valves in the intake manifold (some motors did, some didnt) you may have an extra plug, otherwise if its a long dangled one its for the oxygen sensor as stated above, and also needs to be plugged in

are your fuel lines on backward? its easy to do.

Do your plugs smell like fuel or when you pull them out are they black/fouled.
