this is the 4th ecu ive gone threw now. i have a 1991 integra with a b16 in it. it seems that the problem its having is theres no power going to the fuel pump. i plug in my buddies ecu and it fires right up. any ideas on whats causing the problems? thanks 4 all your help

 

Which ecu's have you tried so far? Sounds like you need an obd0 pr3/pw0 or convert to obd1 and run a tuned/chipped ecu.

 

ive had 2 pr3s and 2 chipped p28

 

and what kind of ecu does your buddy have that works on your car?

 

He has a p72 the car will start right up throw my ecu back in and nothing so I know its not the fuel pump relay.

 

Have you tried your ecu's on his car?

 

Yes and it won't start his car either

 

So you bought four ecus that are ****? Wow! You can ship it out to Chris at Xenocron. He can test and see what is wrong with your ecu.

Check my sig!

 

so did the ecu's that you've tried ever work in your car? like did they work for awhile, then quit?
which injectors are you using?

 

Ya they worked for awhile and then one day they would jut **** out no warning

 

somethings frying the ecu's. which injectors are you using? if you're using saturated, you have to ditch the resistor box and rewire, or buy a delete plug.
if you're using peak and hold, you must retain the resistor box.
that can fry an ecu over time
