8 Codes!!!

[jclayto4]

I had a problem last month with my btteries dying at the same time. So I brushed it off and got the batteries replaced. I went on vacation for 2 weeks and came back to find the truck dead again. So i jump started it and let it run for a min. Then my Edge tuner started blinking like crazy giving me a warning for 8 Codes(V0155,P0046, P0231, P0403, P0562, P0683, P1378) so I shut the motor off. I fugured it had to be the tuner cause I didnt have the problems with the battery before the tuner so I returned the tune to stock and drove to go get gas then went to bed for the night. I went to go to the store this morning and it was dead in the water once again. I am wondering if its a bad ground or some other connection. Thoughts?

All of those codes have to do with low voltage mostly internal to the pcm.

You have a serieous short somewhere drawing off your bat power and you may have fried your pcm. Check all main wireing and connections for short to ground.

Re check your batteries individually for a bad cell/s Do a voltage/amp draw down test while cranking. Test Alternator for short internally, open v regulator.

I recomend takeing it to a starter/alternator rebuild shop for testing and repair.

The alternator tests fine with key on and cranked. I dont have the time or resources to troubleshoot a PCM so it looks like shes going to my Ford guy for a few days. Hopefully I didnt fry the PCM...
