i just did an obd0 to obd1 conversion i got spark i think i got fuel working cuz i can hear the pump and i put enough fuel but it dont start i have a b16a obd1 jdm pr3 ecu chipped with xenocron basemap before i did the convertion the car turned on fine im not sure if i need a resistor box i deleted it and the car turned on fine before but i dont know if i have to have the resistor box for obd1??? anyone have any ideas

 

and i only got 2 codes so far its 21 and 41 witch i dont think cause the car not to start

 

Are u using obd1 or obd0 injectors?Are u using an obd1 distributor? Firing order correct?

 

im using an obd2 dizzy converted to obd1 i got spark injectors im not sure they came with my jdm b16 obd0 unless i wired the dizzy wrong but i do have spark???ill double check firing order

 

did you get the 2 white wires mixed up at the dizzy?


map sensor and tps not mixed up?

 

firing order is good

 

before i did the obd1 convertion it turned on so i dont think the map and tps are mixed
and im not sure about the wires on the dizzy i do have spark

story on dizzy its obd2 with the obd2 clip but it has same wire colors as obd1...

 

tested ecu on my old b16 ef and its good

 

what injectors are is the ecu scaled for?


what about all of the grounds, as well as the one on the thermostat housing?

 

i guess it supposed to have obd1 injectors??
grounds are good i painted my engine bay so maybe the one for the tranny is not so good ill try diff place

i have the injectors the car came with with obdo they turned on with no problem and it had no resister box so im guessing they are obd1 b16 injectors

 

i did better grounds and it sounded like it was going to start but batt died lol so i have to wait on that hopefully thats it

 

nothing still now when i try to start it every couple of seconds it makes a small cloud of fire on the headers....i only have the headers bolted on....its driving me nuts it has spark and fuel

 

my buddy had a similar prob try a new set of plugs.

 

i got spark and they worked perfect before obd0 to obd1 conversion

 

im going to recheck wiring on the dizzy im going to take it all apart and make sure everything is ok wire by wire even if i have spark.....urhhhhh if anyone has any ideas let me know

 

im doing the same thing man. what did you do with your white round plug? by where the resistor box was? sorry to jack your thread man....

 

its ok....i dint have to do anything there and i have no resister box i deleted it

 

I rechecked the wiring on the dizzy and its good rechecked the wiring on ecu and looks fine but still no start im beggining to think its the injectors but any input is still needed

 

To check if you have Fuel...spray Carb Cleaner or Brake Clean in the INTAKE MANIFOLD for 2 Second (with Throttle Body open) and then start the car...if it fires and runs for a couple of seconds, you have spark but no fuel.

Easiest way...

 

well I tried everything so im just switching it back to obd0 sense I cant figure it out for now witch sucks cuz that means no vtec for me and motor will run like **** sense I dont have knock sensor....

 

obd0 injectors you need the resistor box. obd1 injectors you delete the resistor box and wire it accordingly. but i guess you have obd1 since you stated that you have stated the car as obd0 without the resistor box..

what does your obd1 conversion consist of?

 

im having to same problem with my poor mans type r swap in my crx..it turned on fine before i did the conversion and now it cranks but wont start..i knw i got spark cuz it shock the hell out of me..lol and there is fuel going to the fuel rail..im using obs-0 injectors with a resistor box..im going to try the brake cleaner..sorry for thread jackin but i wanna knw whats up..

 

never mind..i tryed the brake cleaner and it started for about 5 seconds but shut off..so im geussing that the injectors aint opening up..what can i do now??

 

I had a ls dizzy obd2a converted at the wiring for ond0
wiring harness obd0 to 0bd1
jdm pr3 obd1 ecu with xenoncron chip

I know the ls dizzy is not the right thing to do but that was only for now and I know ls dizzy work you just have to advance it and cut the ears closest to the headers

I had spark and i could hear the lines feeding fuel to the engine and also did a pressure release at the gas filter so see if i was getting fuel and it was.

right now my motor is on and running but its on obd0

 

its ok men...same thing happen with me with the spark lol I read you tried brake cleaner and it turned on you have obd0 injectors remove the resistor box and it should turn on all you have to do is take all the wires that come out of your injectors that are the same color wire them together and then wire them to one of the 2 wire that is color yellow and black and your car should turn on.....
