ok here is my problem me and jason hunt cant figure out with my car. the car 1996 acura integra 1000cc injector,resister box,neptune, p28 with jumper harness. heres the problem the car is not getting an injector pulse. tried new engine harness,dizzy,resister box,injectors, computer,jumper harness. willnt get a injector pulse with any of that. So we put a 0bd2 ecu back in the car and it fires up and runs fine. im ******* stomped on what could keep the car from running on the obd1 ecu. anyone have any idea?


thanks for any help i can get.

Check the FC sensor?

 

I assume you've put noid lights on the injector plugs? If so, it may be something as simple as a romulator issue, I assume you/Jason have tried to burn a chip with the program?

 

yes we get the noid to light on the when the obd2 computer is pluged in but not when the odd1 is plugged in. ive tried hondas300 in th car and also mine friends uberdata ecu's

 

funny terry. until i get my car running im not goin to buy parts

 

bump to the top please

 

get your trusty meter out... start chaseing wires

good luck man

 

thnaks for the advice brad

 

Bad adapter harness?

 

You've tried two seperate OBD I ECU's? But it only works with a OBD II one. Correct?

Nope that is what I said, it has been changed out and still same problem, this has STUMPED me!!!

 

did you do anything with the injector drivers? Maybe their burned out? Ground is good right? No ground loops?

 

nope ive tried 2 different p28 with my chip and a p72 with my chip yes the grounds are good

 

you and me both terry how is it possiable that it runs on a more advanced obd2 computer and not on obd1

 

anyone?

 

hello?

 

you guy are really helpfully

 

What about all of the ground wires, are those all good? Just trying to think of stuff for ya man..

 

yes. grounds are good my question that i dont get why will the car start on an obd2 computer but not a obd1. what does the obd1 have thats isnt need with obd2

 

Pm Jeff Evans, he is usually knows whats up!

boosted hybrid

 

You arent getting any pulse on any of the 4 cylinders? Any codes on the OBD1 ECU?

Have you verified the P28s you tried work in another car?

 

no injecotr pulse on all 4 injectors ive pulled another ecu out of a car that was running 5 mins earlier and it didnt work

 

You try swapping out the resistor box?

Weird problem...good luck

 

yes i tried that my car is a ******* demon child haha anyone else got any input

He has actually disconnected the resistor box and put stock injectors in too and a stock ecu and still nothing!
