ok, im new to honda tech i couldnt get help from superhonda and g2ic so i hope this site is better. Ok ive done the swap but i cant get it to start the injectors arent firing or the distributor, the motor rebuilt i put crower cams in, a new swap harness the computers used but it works because i put it my zc 4dr and it ran, a brand new in the box distributor and everything. the only thing i see the guy before me had a odb1 vtec swap done at the ecu side of the harness i switched it back but nothing i dont know what to do help me

 

when i turn on the switch the ecu light does come on then off, fuel pump is priming 91 ecu, 91 distributor, 93 motor mpfi swap done all new fuses motor got a ground kit all lights work cant figure it out.

 

what type of injectors high impedance, low impedance ? resister box? what Ecu?

 

low injectors (2.3 ohms), the resistor box was already on the car and im using the odb0 pr4

 

it could be your wireing. who did the mpfi wireing? or it could be your main relay. or even your ignition switch.

 

the guy how had the car before me had a gsr or a b16 in it before i put it back stock then did the the swap at the ecu the wiring harness is store brought

 

Rebuild huh, have you checked the compression? does it turn over? what does it do when you try to start it?

 

even though you bought a new harness doesn't mean it will work. 1st - check your wiring again, if they did or you did a dpfi to mpfi make sure its correct. 2nd -main relay. 3rd - fuel pump. 4th - injectors.

 

yea fuel pump is a walbro works fine, forgot to put on the injector seal one day and i pumped about a gallon in a second lol, but the injectors i have 2 sets ive switched and switched but nothing as far as the wiring its getting there im checking it wire by wire i was wondering what this white and red wire at the ecu no other ef has it but this one and its not on the wiring diagram

 

Well

 

i got it to start yesterday , woot, now i got to fix the high idle

 

nice, is the throttle body closing all the way?

 

im going to trow some coolant in it and see what code it trew i saw it but im not sure i think it was code 14

 

ok, i ran into another problem i started it, ran a little and cut off now im not getting anything again. the ecu blinked when it came on like it is suposed to but if i crank it for like 5 to 10 seconds the computer led comes on and stay on ive heard that that calles for a new ecu but i put it in my dohc zc and it started right up, what is going on?, and on both cars its trowing a code 4 and 9 i dont get it

 

I had this problem with my b20 swap into 89 hatch. It ended up being a ground wire on the back side of the motor under the intake manifold on the intake side. I got it to start sometimes and would drive it, but with the vibrations it lost connection and the car died. Be sure to check all your grounds, it may just be a bad ground. Good luck
