i recently swapped a obd1 b18c1 swap into my wagovan. Im using the obd1 p72 gsr ecu, with a jumper harness,adj fuel pressure regulator,walboro 255. now the car is extremely hard to start and will only start if u spray carb cleaner in it. idk what i did wrong i followed the instructions down to the tooth and rechecked my harness to just make sure i dint mess up anywhere. can anyone give me any ideas to what it might be please i would realy like to have this ready for the next honda meet in nj next month thanks and pm or email me suggestion big01fredo2007@yahoo.com thanks

 

might help if you post what you actually did. from there we can try and help.

 

nothing i took out old 2 injector motor and swapped in the gsr and it will start but only if u put carb cleaner into it otherwise it just turns over and tries to start but nothing

 

so now you should have 4 injectors, right?

which injectors are you running? obd0? obd1 or obd2?

did you remember to delete the resistor box if you are using obd1 or obd2 injectors? vice versa for obd0 injectors

 

so i changed the fuel pump thinking it was fuel pressure considering old old motor was a 2 injector and installed a blox adj fuel regulator and still nothing

 

you did do the DPFI (2 injector set up) to MPFI (4 injector set up)? RIGHT?

 

yeah did you convert to mpfi from dpfi?

 

obd1 and yea i eliminated the resistor box

 

from the sounds of it, i dont think you did.

 

thats not what i asked. i didnt ask if you converted to obd1, i asked if you converted to MPFI?

 

yea i converted it i had to re run all injector wires straight to jumper harness and same for dizzy

 

why? recheck that wiring, i bet that is where your problem is.
