i have a 91 crx dx with a b16a turbo with a p28 chipped and tuned ecu
i was driving one day and my check engine light comes on and the motor slowly bogged out until it shut off, i tried starting it but wouldnt start

now it sometimes starts and sometimes doesnt, when it does, everything is fine but most of the time it doesnt

i think it has to do with fuel but i hear my pump turn on and prime

any help would be great

 

What's the CEL code? The ECU is already telling you what's wrong...

 

the cel code is 68 and ivedone some research and 6 osnt for anything other than an ecu malfuction

 

So there's your answer. Try a different ECU or a different chip.
