I have a 2003 protege 5 that was rough idling for a couple months sometimes it would even shut off on me. A couple times I would turn the ignition to the on position and would completely loose power no light in the dash or radio nothing. Eventually the symptom happened while driving, going about 45mph the car shut off power on me my speedometer went to 0 and after a couple seconds power came back car was still on even, two days after that on the highway going about 80mph the car shut off on me power came back but engine was off I pulled over and car would crank but wont start, originally i assumed it was the fuel pump because I didnt hear it prime so I bought one and replaced it, new pump wouldnt prime either we checked the pumps with a battery and they both work however they will not prime on the car, I replaced the relay and it still does not get power additionally my OBD2 no longer works it wont even read that its hooked up to the car, I saw a YouTube video where a guy jumped his relay and has been using a switch on his pump, but I would like to see if you guys can help with this, my friend is leaning toward the ECU because of the electrical issues and the fact that OBD2 doesnt scan what do you guys think?
