So i just got done diagnosing an ECU fuse issue i was having with my 89 crx with a b18a1 engine swap. The only issue is that i am only getting fuel from one injector. The fuel pump is working fine and there is more than enough fuel coming from the pump because when i take off the fuel rail, it goes everywhere. One thing i noticed is that when i take the connectors off of the injectors and re-attach them, only one of the injectors will click (fire.) Any ideas? I have a whole turbo kit i want to get started on but first want to get it running with the stock injectors.

was the motor sitting for awhile? If so they could be clogged up.

yeah the motor was sitting for a long time... how do i go about cleaning them? i already took a rag to the gunk on the end of them

Soke them in sea foam. For a few hours that helps I lil bit. But also check ur ecu could have fried something in there happend to my friends car fried the number 3 and 4 injector circuit in the ecu only injectors 1 and 2 worked.... . An u said u where haveing problems witth the fuse poping for the ecu so try another ecu if u have one or can borrow one

allready took the double ecu route. have two of them and get the exact same issue with both. One was new just to make sure that wasn't the issue. But on the subject of the ecu, there is a lot of flashing coming from the ecu when the car turns on. Should i get a code reader or is there a way to figure it out just by the blinking light?

Wat ecu are you running?? Is it obd1 or obd0 ecu??

rlembitz

well the b18a1 is out of a 91 acura integra so i would think that it is obd0 but because it was right on the turning point of the years, but i cant be sure.

if there isnt a jumper harness between the ecu and the cabin harness then most likely its a obd0 ecu jus read the #'s on the sides and u can do some research thru google

sorry didn't reply for awhile, i had to go up skiing (colorado is great.) but anyways if it is obd0 is there a thread on here that shows you all the codes that the ecu throws? i searched and found one that just discussed two types of codes. Just wondering if anyone knows of one off the top of their heads.
