Hello everyone, here is my story, I bought a 2006 manual acura tsx navi about a month ago, It had some issues that I was going to take care of, until this happened: After replacing my ac compressor because the bearing was loose, I washed my car with a pressure washer (just the outside), noticed that my engine ground on passenger side was broken so replaced it with a wire and my buddy brought his scanner over. I went on a drive, the car kinda started to overheat beacause the fans were not turning on ( temps switch connector was corroded and it broke the pins), thats not the main issue, so i parked my car, plugged the scanner in, cleared the codes, then BOOM, I try starting the car and I only cranks, doesn't start. The fuel pump doesn't prime and the immobilizer light is flashing and the gauge doesn't display the rpms when you crank it, two new codes popped up : B1169 ( gauge control module lost communication with the pcm) and B1168 same thing. The thing is that the immoblizer system disables the injectors not the fuel pump so there is a communication problem. Then I looked under the hood removed the ground wire I just put on and whent to sleep. Didn't really know what to do so Istarted googling, what could be my issue, I find out that the ecu tends to go bad in these cars, so then I came back to the car the next day with the same scanner. I did a gauge cluster self test it all workes well exept on thing, It said F-CAN NG witch means f canbus not good, I dont know what to do with that. So I decided for some reason that my ecu is bad, when to the junk yard to get an ecu, but knowing that it has to be programmed, I also took the key and the immoblizer itself, so I wont have to get it programmed. Got home plugged it all in : key still flashing and no fuel pump prime....I have no clue what to do next, but the after turning the key on and off 15 times or so I hear the fuel pump prime but the key is still flashing, I am confused but its because i forgot to put the junkyard key into the immobilizer hole( i did not change the ignition, so i have to use both keys to start my car), so i put it in immobliser light goes away and I try to crank it 1.....2......car runs out of battery, so I put my almost new fully charger battery out of my rsx in it and we're back to square 1. Immoblizer light flashing and no fuel pump prime. Tried to start it a couple of times. Nothing.... Went to do other things

I now decided to replace my gauge cluster because why not, got a junk yard one, drove around in the rsx with the tsx battery to charge it up, noticed that it was kinda weak but, its fine. So replaced to tsx cluster with the new one, no difference.... put the original battery back in, left the key on trying to find whats wrong, at some point, turned the key off and on and I hear that fuel pump prime again, so I put the junk yard key in again and crank it its cranks super slowly but it starts but the battery almost whent dead. And since then the only way to start my car has been : crank it untill the battery is almost dead, wait untill the green key goes away and fuel prime returns, leave the car in the on position, jump the battery and start the car. The car drives ok, it never dies when on, I can close it and start it back up with no problems, but if I leave it for more the around 5 min, I have to redo the whole process aigain. So yeah here I am, dont know what to do, I hope someone can help me. Dont have the money to send it to the dealer really, at least for now. I read thru a very big amount of threads here and on other forums but I cannot find anything or with a solution to this problem. Thanks and I think i forgot to mention this but the scan tool does to communicate with the gauge control module and these codes dissapear when the green key is not flashing and the car is starting. So in summary b1168 b1169, f can ng , no fuel pump prime and green key light blinking. Every single other electrical thing works in the car, exept the power mirroirs but the car has to be on i think. Hope someone can help me with a solution to this. Thanks.
