I need some help with my 00 civic ex. It was auto but i took my engine, engine harness, trans and ecu out of my 96 civic lx and converted it to manual. I soldered the three wires together to trick it into thinking its in park already. So now it will try to start but wont. I checked the fuse and pgm-fi relay to the fuel pump and they're getting power but the fuel pump wont come on. So i hot wired the fuel pump and the injectors arent pulsing. Also when i turn the key to the on position with the engine off, the check engine light doesnt come on with the other dash lights. I was told that means it's not reading the ecu? Any help would be greatly appreciated. Thanks guys

Does the starter crank the engine?

Reverse the hot wired main relay and check whether the G3 transmission ground and the G101 ground on the thermostat housing are clean and tight.

Ok. yes the starter does crank the engine. Those two grounds are clean and tight. Can you explain how to reverse the hot wired main relay? Im not too good with electrical. Also is it ok to use the engine harness from my 96 civic?

Just reverse your wiring modifications.

This could be the problem. The 00 Civic is OBD2b whereas the 96-98 Civic is OBD2a.

Ok thank you

Do i need to use the intake manifold from the y8 that came in the car originally?

97civkid

If you are using the obd2b harness, that is your problem, I was having almost the same problem

phreshEK1

Im using the harness out of the 96 civic in the 00 civic

97civkid

there are a few differences in the pin outs from obd2a-b, if you swap the harness you should be golden

97civkid

Check for fire from your plug wire, I am betting there is none

phreshEK1

Ok im swapping the harness when i get off work. Ive got spark just no fuel.

phreshEK1

so i put the 00 harness back in the car and converted the distributor and the car still won't start. I don't think the car is detecting the ecu

phreshEK1

I will send 25 dollars through pay pal to whoever figures this out

HondaPartsHero

Do you have proper spark? Fuel? Narrow that down first.

97civkid

What ecu are you using?

phreshEK1

Ive tried the y8 ecu which came in the car and the y7 ecu thats from my 96 civic

phreshEK1

I have spark no fuel. The fuel pump is good, the fuel pump fuse is getting power, the pgm-fi relay is good and getting power but its not getting power to the fuel pump and the injectors arent getting a signal. When i turn the key to the on position all the lights come on except for the cel.

phreshEK1

Ive been told to put the y8 dizzy on it. Will that work?

97civkid

They are the same, but which side is the relay that u checked? Check the one on the opposite side

phreshEK1

The relay under the dash on the passenger side is the one i checked?

youknowme87

Starter

phreshEK1

I got it running. I missed a plug

phreshEK1

Will using the auto ecu make it spit and sputter when im accelerating?

97civkid

No it shouldn't, I've been using mine since I swapped it about a year ago

97civkid

There are 2 plugs that look the same, map and tps try switching them
