Bought a 92-95 civic hatch si shell. The shell has a obd1 abs underdash harness in it from the previous owner i bought the car from. I believe it's a obd1 integra harness, i don't know if i need it to be plug up to start the car or not, but anyways, i swap the motor in and when i turn the key for the fuel pump to come on, it doesn't. I don't hear my fuel coming at all. When i turn the key to start the car. I get nothing, not a sound, just the click from the key turning.

I asked some friends they said for me to check main relays and clear all crosions from the ground (the ground on the themrostat, tranny, and negative on the battery).

I replace the main relay with a working relay and clear all dirt or corosion on the grounds. Still i get the same things. Nothing.

Please if anyone has any idea what might be the problem. I would really appreciated it.

 

check your fuses, make sure theres no break in the wire from the battery to starter and battery to fuse panel. Computer plugged in?

 

checked all my fuses and yes have a p06 plugged in.....

 

Are the crucial ground wires attached to the thermostat housing and transmission clean and tightly connected?

 

yeah that is 100% sure

 

bump

 

Do any dash light illuminate when the key is turned to ON(II)? Does the CEL stay ON?

Have you checked the ignition switch?

If it's manual transmission, have you checked the starter switch at the top of the clutch pedal?

Does the starter get battery power at the large Blk wire?

 

yes, the cel does stay on. haven't checked the ignition switch. yes, it's a manual. yes, checked that starter switch. that is the yellow switch right???????? i don't know on the battery power.

i need my fuel pump to work first, cause it suppose to come on before i even try to start it. i don't know why it's not coming on too....

 

Pull the CEL code from the ECU.

I was chasing the starter problem because it might reveal the problem with the fuel pump.

Have you checked whether the fuel pump gets power when the key is turned to ON(II)?

Have you checked whether the Blk/Wht wire on the starter solenoid gets power when the key is turned to ON(III) and the clutch is pushed down?

 

haven't done any of those checks, but will do it tommorrow morning. i mean i need to get my fuel pump to activate? don't know if it's the main relay or what???

 

you need to check power like Ron said. But it sounds like a ground issue to me. Does your main relay click when you go to crank the car (if it does its ground for sure, since you said you replaced the relay already).

 

i can't even crank the car because the motor won't even turn...maybe i'll double check my grounds again tommorrow...i'll let you guys know what happens...thanks so much for the help....

 

yes i know. Instead of cranking it will just clck the main relay (depending on how bad ur wiring is). In mine it would turn i belive but it would click the relay pretty bad.

 

it doesn't even click on the main relay...it's like nothing works...man it's giving me a headache....

 

Do you have a digital multimeter. If not, one can be purchased for $15-$20. It will be crucial in helping you pinpoint the problem. If the main relay doesn't click, then double check fuses 31, 24, and 18.

 

damnit RonJ you always beat me to this lol.
I was just going to tell him to check the fuses. And i was gonna lokup which ones too in my Honda Manual lol.

 

which fuses are those????????

 

bump

 

he told you which ones they were.

 

are those fuses under the dash or under the hood???????

 

31 = hood

18 and 24 = dash

 

Have you tried another ECU? probably is bad.

 

man, i took out the whole underdash wire harness and installed a cx harness. hopefully it works, if not, i'll try a new ecu and replace all fuses and relays...well let you know know what happen...thanks to all for helping out....

 

well, today finish installing the whole cx harness (to ecu), the original po6 ecu is still in good condition (used it on my sister's ex and it worked), switch fuel filter, checked all fuses, replace main relay, changed the underdash harness (the harness from driver speaker to the back speaker to the fuel pump plugs, Yes, that harness), went on to DOUBLE CHECK IF I DIDN'T PLUG UP ANY HIDDEN PLUGS. guess what guys.

IT STILL DOING THE SAME THING...M******* F*********....

when i turn the key (I), the beeping noise come on. when i turn the key (II) i don't hear the fuel pump activating or nothing, just on the cluster the oil and check engine light come on, the check engine light stays on forever too, it does not blink or anything, it just stays on. when i turn the key (III), NOTHING HAPPENS....

PLEASE ANYONE WHO MAY KNOW WHAT THE PROBLEM IS, PLEASE, PLEASE HELP ME OUT...THANKS.....

 

Have you tried to pull the CEL code? If you have and no code is retrieved, then test whether the MAP sensor is getting 5V from the ECU.
