Hi, my name is Alexander Huffman. I have the car listed above S, FWD. It is currently in the shop, I spent two months trying to figure it out and the shop is even having problems. It will start but will constantly search for an idle and eventually shut off. I get no throttle response, the throttle body isn't getting power, it does not even actuate when you press the gas. Also they have put a new ECU in and it wont communicate at all, with the new or old one. The code it was throwing before it stopped communicating was p2118. So far they have put the new ECU in, nothing. Checked all the fuses, nothing. Removed my remote start security system, still nothing. At $95.00 an hour I can't afford to keep paying hour after hour, this is my only vehicle and I have a baby on the way. Do you have any advice or suggestions that I can mention to the mechanics to test and look for? Thank you for your time!

Hello,

In the diagrams down below I have included the diagnostic troubleshooting flowchart for Direct Trouble Code P2118 for your vehicle from the vehicle manufacturer. I have also included the initialization and registration guide for your vehicle from the vehicle manufacturer. Please go through this guides and get back to us with what you are able to find out.

Thanks,
Alex

Thank you, but here is my biggest issue, no scan tool. Mine nor the shops will communicate at all, so therefore we cannot reset my original ECM or the one they got because they though the ECM was the issue. I just spoke with the mechanic and he said he was going to test the voltages on all the ignition wires and everything. The weird thing is, when my car started this problem was because my key got stuck in my ignition and I had to remove the key cylinder to get my key to release, then this problem started after I got my keys reprogrammed (had to learn on-board programming). I though the ecu was my problem and I got a used one out of salvage and of course it wasn't flashed right so it would start and immediately die. Shortly after I got frustrated, and plugged my original ecu back in and bam, it started, I had throttle response and it worked for a whole day. During driving the ECU went back into fail safe and I lost throttle response again. After unplugging my ECU and plugging it back in, it would go back to working. Twice this happened and then it quit again and hasn't worked since.

Hello again,

This could be a problem with the transponder key amplifier with your vehicle's security system. In the diagrams down below I have included a description of the vehicle's security system and a diagnostic flowchart for troubleshooting for you. Please go through these guides and get back to us with what you are able to find out.

Thanks,
Alex
