Injector Solenoid Driver Cylinder 1 Mechanical System Not Responding or Out of Adjust Hello all, I am new to this forum and this is my first post. I've gotten myself into quite the pickle. I will lay out the timeline of events below... Fault Code 1139 (See Thread Subject Explanation) - Total times active 7 - Will go inactive after a short time - The amber engine light cleared itself without assistance once and returned 30 minutes later Timeline - May 24 the truck was de-mandated. I was told it would be a "full de-mandate." - Immediately after picking up the truck I noticed the fuel economy was much lower than normal. - I contacted the shop and was told this was normal. The problem will fix itself in 2-3 weeks. - The problem obviously didn't fix itself in 3 weeks. I decided to perform an overhead adjustment, as it was do anyhow. I thought maybe it would help a little with the fuel economy issue. - Overhead adjustment was performed on June 13. - Fuel economy still poor. I have now gotten the first 1139 fault code after overhead adjustment. - Contacted shop and my local Pete dealer. Peterbilt advised I "go for the kill" and replace the number 1 injector to save time and money on troubleshooting. They knew I recently de-mandated the truck. - First shop replaced the number 1 injector on June 17. This was after the truck failed a fuel injector test performed by the same shop. - The shop ended up breaking the threaded connector on the harness going to the number 1 injector and replaced the harness with a used one they had on hand. - The fuel economy is still poor and fault code 1139 has returned after these repairs. - The shop claimed I bought a junk injector from Peterbilt. I bought a new Cummins brand injector. They did no troubleshooting to come to this conclusion. This was an over the phone conversation. - Decided to try another shop. - On June 29 the second shop has completed repairs. They stated the first shop did not remove the DOC and this was 100% related to my fuel economy issues and my fuel economy should greatly improve. It did not. I was also told upon checking the ECM they couldn't find anything wrong with the tune, "it looked clean." - Upon payment for repair services I was told a different story. That the tune was bad and they had to do another full de-mandate. I was told the tune was trash. 2 different stories from 2 different people at the same shop. I was also informed my truck passed the injector testing the first shop had previously done and failed. - July 1 code 1139 is back and fuel economy is still just as awful as day one. I still have all original symptoms. The only thing that appears to have been done at the second shop was drill out the DOC. I am waiting for July 5th to roll around to get my truck back into the shop. I have been searching the internet to try and find answers. Any help would be greatly appreciated. | |||
