Long story short....alternator conked out. Prior to doing so I noticed the CEL and decided to run a code scan to maybe figure out some things. Well, today before work I hooked it up but wouldnt start (evn with the battery charged and the assistence of a jump pack). It jus cranked and cranked but wouldnt,turn over. Doing so.....it came back that there were 0 codes. What?

I was told it could be 1 of 2 things......1) blew the ecu relay and its not allowing the ecu to function or.....2) the ecu isnt geting the right amount of power to access the codes?

Im trying to figure out what codes are being thrown as ive known about a misfire code and with my,taxes im buying new plugs,wires,and coil pack assembly. But was also figuring if I,need to purchase a crank position sensor, cam position sensor(think I,had a code for this when I got the,car) and o2 sensors, etc. any help with my problem would greatly help. Thanks fellas

 

If you can connect to the ECU then it's fully powered and not the issue. Check for fuel and spark first, then go from there.

 

If the battery died at one point, it probably reseted the ECU hence why the code isn't there anymore. You'd need to drive the car for several miles for the codes to come back on.
