Bad ECU or Bad S300?
Car 88 CRX
Eng H22A
ECU P28
S300
Rywire Custom Harness
The problem I am having is the ecu doesnt turn the fuel pump on (or start). I plugged in a PR3 and the car runs. I replaced the capacitor at C14 because I heard they go bad. Still nothing. So I am wondering if the S300 is bad or the ECU. Before I replaced the harness everything ran fine. I know the harness is good because with the other ECU, it runs. I would try another P28 w/S300 but no one around here has one. I live in 29 Palms, CA and its in the middle of nowhere so there isnt a local dealer anywhere.
I didnt want to buy another socketed P28 and then later find out the S300 is bad.
Any ideas would be greatly appreciated.
