The_aSSet Posted November 2, 2012 Author Report Share Posted November 2, 2012 I'm running the beta, ill do all that tonight or tomorrow. Thanks for the tips. I'm gonna check the grounds again and the voltage going to the pcm pins Quote Link to comment Share on other sites More sharing options...
The_aSSet Posted November 3, 2012 Author Report Share Posted November 3, 2012 Alright here we go, I literally did everything y'all suggested and still nothing. I checked the ground location to make sure it was good, checked the grounds going into the pcm via the pins, checked the voltage going to the pcm and its at a constant 12.3v checked the voltage going to the obd port and its at 12.0x fairly consistently. Took out the radio, radio amp, and onstar fuses, tried parking lights and rereading the tune (which it does read fine) tried to write it with one change and, same error. I'm at a loss of what to do. Although there are some weird things. 1. Fuel gauge says empty even though I put in 5 gallons of new gas a few days ago 2. Fuel pumps don't turn on when the key is in run, I checked the pcm pin that controls it and its at 12.3v as well. And I switched the relay with the drl relay and still heard nothing when the key is in run. they are supposed to turn on correct? For like 2 seconds? Any ideas? This is very frustrating. I have a total of 3 grounds connected in. the engine bay on the engine, 1 behind the intake, and 2 on the drivers side on the block above the oil pan and below the head. I checked the voltage from the raw metal of the block near the 2 grounds being careful not to touch the terminals themselves and it read 12.3v steady. Did I miss a ground somewhere? Is one not supposed to be on the block? Checked voltage to the frame as well and 12.3v constant. I want my truck running again Quote Link to comment Share on other sites More sharing options...
idahoBLKss Posted November 5, 2012 Report Share Posted November 5, 2012 i would check every fuse in both boxes specially the cigarette lighter fuse (should be in the under hood fuse box, blue fuse right next to the radio fuse).if thats not it i would check every single fuse easy to do with a flash light .you should be able to hear the pump prime in the on position. sorry man wish i knew more.have you tried writing a different tune, make sure the vin matches yours, are you writing a speed density tune for the first time? if so you need to buy more credits.... just throwing ideas out there.

The_aSSet Posted November 5, 2012 Author Report Share Posted November 5, 2012 Checked all the fuses when I checked the voltages all was good. I've tried writing a different tune and I made sure the vin matched. Speed density was already on there from the procharger and its still speed density so no change there. I appreciate the ideas. Even tried asking on hptuners forum and not much there in the way of answers/ideas. Ill email support later this morning. Quote Link to comment Share on other sites More sharing options...
JC03SS Posted November 5, 2012 Report Share Posted November 5, 2012 why do you hide your vin? Prob the same reason people cover there tag,because that's really no ones business. How's the truck coming nick? I hope someone can help you get this figured out. I know it's frustrating but hang in there bud. Quote Link to comment Share on other sites More sharing options...
The_aSSet Posted November 8, 2012 Author Report Share Posted November 8, 2012 Something weird happened last night, fuel pumps came on when I plugged in the pcm with the key on, not sure why but I know this is the first time they have because I had a small leak from the passengers side rail that was misting gas onto the firewall. I took the battery out just in case and im gonna charge it today since it was low from messing with things then see if anything has changed loading the tune or if the fuel pumps will prime again. Fingers crossed. Quote Link to comment Share on other sites More sharing options...
rickyrick562 Posted November 8, 2012 Report Share Posted November 8, 2012 Good luck bro I got my fingers crossed for you I wanna see this thing in action Quote Link to comment Share on other sites More sharing options...
idahoBLKss Posted November 8, 2012 Report Share Posted November 8, 2012 man buddy you should always have the battery unplugged when pulling the pcm in or out. Quote Link to comment Share on other sites More sharing options...
The_aSSet Posted November 8, 2012 Author Report Share Posted November 8, 2012 Ill remember that. this year is the first time i've even taken it out of the truck, its always been tuned with it in the truck Quote Link to comment Share on other sites More sharing options...
Fourtraxjay Posted November 20, 2012 Report Share Posted November 20, 2012 Sorry I don't have time to read the entire thread at the moment, but 1 observation. I had this exact same problem using EFILIVE. I think on both of my SSS's. The solution was to uncheck the "use high speed" button. I see your program has the exact same box and you have it checked. It will take longer to load a tune, but at least it will load. Also make sure you truck's batt is really good, I don't know if I am way off here, but it seems to me that many attempts to load, reboot, reflash, etc. sucks up juice. Good luck Jay Quote Link to comment Share on other sites More sharing options...
The_aSSet Posted November 20, 2012 Author Report Share Posted November 20, 2012 I got it fixed lol it was a ground of course. Behind the intake there are 2. I was told 1 by someone so I only looked for 1 but its all good now. Quote Link to comment Share on other sites More sharing options...
