careercadaver Posted July 27, 2014 Share Posted July 27, 2014 Swapped the longock in my LGT and went to turn it over and cranked and almost started. I instinctually let off the ignition but it wasn't quite enough to keep it going. The second attempt to start the car I had a code on the cluster of "Er hc" and if you leav the key in or about 1min ACC begins to flash on the clock... Fuel pump does not prime, fans did not kick on (as mine usually do on start up), and there is no power to the radio. From what I've gathered this is an issue with CAN BUS but I've seen nothing about the flashing ACC in combination. http://img.tapatalk.com/d/14/07/27/4ega6una.jpg All my grounds are in place, battery is charged, I've replugged in the main harness and reset the ecu and still nothing. Any help would be appreciated. Link to comment Share on other sites More sharing options...

Max Capacity Posted July 27, 2014 Share Posted July 27, 2014 It has to be something simple. After the ECU reset, did you leave the key in On for 10 seconds before you tried to start it ? 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD).

I did not. Left the negative terminal off last night. I should have time to play with it tomorrow. Gonna start with the starter. Long block, you using that blocks harness ? Same harness. Had the shortblock rebuilt after it swapped it in Dec. Block failed as a result of premature ring wear from corrosion on cylinder walls. Link to comment Share on other sites More sharing options...
cryo Posted July 28, 2014 Share Posted July 28, 2014 Check the harness above the turbo on the passenger side to make sure its plugged in and security clipped as well as main engine grounds.

Zac88 Posted July 28, 2014 Share Posted July 28, 2014 Grounds on the drivers side near the TGVs could be the issue as well. Link to comment Share on other sites More sharing options...
careercadaver Posted July 28, 2014 Author Share Posted July 28, 2014 I'll double check and possibly add a ground. Never removed the grounds from the block...kinda weird that they wouldn't be sufficient after 3 weeks but I suppose it's possible. Link to comment Share on other sites More sharing options...
Max Capacity Posted July 28, 2014 Share Posted July 28, 2014 10 years old....who knows. Good luck. If the ground path is not good the ECU will not get it's test signal back in time. Cost me $200 to learn that lesson on the Civic. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

careercadaver Posted July 30, 2014 Author Share Posted July 30, 2014 I'm thinking that could be contributing. :/ I'll reaffirm...again. Another odd thing is when the ignition switches over to ON I have no power at the OBDII... Link to comment Share on other sites More sharing options...
cryo Posted July 30, 2014 Share Posted July 30, 2014 I'm thinking that could be contributing. :/ I'll reaffirm...again. Another odd thing is when the ignition switches over to ON I have no power at the OBDII... That sounds like a ground for sure. I have had a couple AP customers have this issue after major installs and turned out to be the engine grounds under the hood. If anything loosen them and retorque just to be sure.

careercadaver Posted August 1, 2014 Author Share Posted August 1, 2014 It was the grounding block on the back side of the TGV's. Must have forgotten to tighten it down. Glad it was something simple... Link to comment Share on other sites More sharing options...

Fuel pump is constantly running. Sounds lick it's stuck in test mode...car ran with no issues for the last 4K. As always, any help would be appreciated.

careercadaver Posted December 24, 2014 Author Share Posted December 24, 2014 I have not. Got busy with the holiday...thanks for the reminder! Link to comment Share on other sites More sharing options...
careercadaver Posted December 25, 2014 Author Share Posted December 25, 2014 Underdog has been giving me some suggestion. PM'd Frank_ster but I've yet to hear back. Not expecting a lot with the holiday. Tried the force flash and ecuflash is acting like it cannot read still. Prompts us to look at previous log for reference and says its in the middle of a previous log session. Also, the temp gauge is maxed out...

Underdog Posted December 26, 2014 Share Posted December 26, 2014 Based on the symptoms you've described it sounds like a high speed CAN issue which could be related to the ECU, BIU, or ABS modules, or the wiring in between/powering those modules. Any chance you damaged the wiring or the ABS module during the underhood work? The Crimson Dynamo Link to comment Share on other sites More sharing options...
careercadaver Posted December 26, 2014 Author Share Posted December 26, 2014 It had been running beautifully for 6k. 2k on recent tune and was literally warming up before I decided to read it. I don't believe there's any wiring that could have been disturbed. Link to comment Share on other sites More sharing options...
Underdog Posted December 26, 2014 Share Posted December 26, 2014 Have you checked the ground path from the wiring harness to the engine (the one that was loose before) and the ground straps from the engine to the chassis? You can try reading resistance between the harness ground lugs and the negative terminal from the battery. The Crimson Dynamo Link to comment Share on other sites More sharing options...
careercadaver Posted December 31, 2014 Author Share Posted December 31, 2014 I have not. I'll try and grab a multimeter here soon. Going to recheck at the fuses under the dash and make sure something wasn't missed. Everything under the hood is good. Had a buddy, who works at Subaru, come over last night and he brought with him the Subaru obd2 they use at the stealership. It was unable to communicate with any system of the car but threw this list of codes... http://tapatalk.imageshack.com/v2/14/12/31/9c6dd73b0ea112f83fbf96d24804847d.jpg Link to comment Share on other sites More sharing options...
