i am really close on giving up on this car. injectors 2 and 3 sprays fuel constantly while injectors 1 and 4 kind of goes lean. then, i tried to rewire the fuel injectors manually (ran each + wire straight from the ecu all the way to the injectors) and it wouldnt spray any fuel at all. i wired it back the way it is and still the same ( 2 and 3 sprayed fuel continuously etc etc.)

i tried messing again with the wires just to experiment and now all four injectors spray fuel at the same time (not continuously).
anyone had this problem before?

What should i look at next? any advice/help would be REALLY APPRECIATED. THanks

 

oh, btw, this is a 90 crx si with a b16a swap.

 

Either your wiring is messed up or the ecu is bad. Try:

Another ecu, even the stock pm6 ecu

Moving the injectors around, swap 2,3 with 1,4 and see if the problem is mechanical to the injector

Have someone who really knows wiring look at the car.

BTW do you have the correct injectors? Peak and Hold's and saturated injectors cannot be mixed up without rewiring the resistor box.

 

i tried another stock pm6 ecu. i was using a zdyne one.
ill go ahead and try swapping it out..... i remember mike yonke (taylor's buddy) telling me that he replaced some injectors. ill get back with you on this one. thanks for the info.

 

definitely a wiring problem. but i dont see how i can mess up the wiring on the fuel injectors. btw, the injectors are STOCK.
the ecu is not bad coz i have tried 2 other stock (pm6 ecu) and it still didnt work

how would i go about bypassing the stock wiring on the injectors? where should i run the wires? please help
