I swaped my ed with a b16 i did all the wiring i have spark but i dont have fuel. I unbolted the fuel filter to see if i was getting any and nothing. I cant tell if i hear the fuel pump or not but i think i dont and it was working perfectly before the swap.

on the ecu i added the extra wires for the 2 extra injectors i dont have a resister box but i think i have obd1 injectors....is there a ways to tell if they are obd1 or obd0 and shouldnt i still get fuel to the fuel filter even if i dont have the resister box?


I took this motor out of another ed i have and it didnt have a resister box thats why im thinking they are obd1 i didnt swap the motor into that car but i was running before i swaped it out. thanks


ps: i did the dpfi to mpfi convertion i still havent done the wiring for vtec want to make sure the car turns on first.

 

listen for the fuel pump. if you dont hear it the problem is probably the main relay. re solder the broken joints of just replace it

 

When you turn on the key,
Does the check engine light come on then go out
or does it stay on?

If it stays on,check this fuse:

 

no it goes off after like normal i checked all fuses are good the car is lifted in the front because it doesnt have the front wheels but i dont think that would cause that

 

I did notice that when i did my dpfi to mpfi i notice where it says to put c1 in b10 and c2 in b12 ....in b12 there was a wire (white/red) and on the guide it said it was supposed to be empty other than that i dont think i did anything else wrong besides not having the resister box.....

 

btw i touched the main relay while i turned on the ign switch and i feel it click so i dont think the relay is the problem ill try and see if i can hear the fuel pump again since there is less sound pollution

 

yeah no fuel pump priming.....

 

ok i was thinking....i dont know if this could also be the problem like i said i think i have obd1 injectors so i did the resister box delete so i took all my red/black wires witch are 4 and connected them together with "both of the yellow/black wires that come out of the dx injectors wiring" could that be the issue that i used both of the yellow/black wire from the injectors? or it does not matter?

 

tried it with only one of the yellow/black and with both still no fuel pump prime.

 

ok so i got the car to turn on.....the fuel pump was not priming so i checked power at the main relay wiring sience its connected to the fuel pump i aplied power directly theres a yellow/black wire witch is the positive and a black witch is the ground i aplied power to it at the main relay wires and i herd the fuel pump prime.

Does this mean the main relay is bad or is there something else for now i have power to the fuel pump with a wire where the main relay is and car turns on like normal.

 

i don't know if it has anything to do with the B16 swap or what but we had the same issue in my brothers CRX when we did the B16 swap...what we did was just stick a wire in the main relay harness plug that was for the fuel pump and ran it all the way back to the fuel pump and stuck the wire in the harness plug and it ran perfect no problems. if you have a hatch or sedan it will be under the back seat where you need to run the wire, if it's a CRX it's under the storage compartment but same general place

 

thats basically what i did but i just took the wire from the fuel relay and gave it 12v for now
