just picked up a 2011 ram about a month ago.. today i was running home to grab some tools, pulled up to the garage, shut it off and when i got back in it wouldn't start, the etc light is on the dash, it will not even attempt to turn over, i removed and cleaned the tb, no luck, pulled the cables off the battery and let it sit, still no luck,, the battery tests ok, no corrosion on or under the fuse box, fuses all test ok... does anyone know of this issue, should i break down and buy a new tb? start checking wires?? maybe a relay somewhere....i'm kind of at a loss
any help would be greatly apreciated

Sorry to hear about your issue, that is pretty strange. Anyway to bring back to the place you picked it up from? Call the prior owner and ask if he or she had issues such as this or installed some type of "kill" switch that was not mentioned.
i had that thought, i'm stuck until monday as i bought it from a dealership out of town.. i've read about a neutral switch issues so i've tried having it in neutral to try to start it, also checked out linkages on the transmission, everything seems ok.. i'm working on lining up a reader to see if its pulling any codes etc.. curious to see if im getting proper voltage at the pedal vs to the servo in the tb but for now i was just curious to know if anyone else has had a similar issue kind of thing
I've tried both key fobs, one of them i recently replaced the battery... still no luck, havn't had a chance to check the starter solenoid as the computer in the truck its telling me its something to do with the electronic throttle control.. so either the the tb (throttle body) or the pedal assembly from what i've read... also read of issues with a faulty temp sensor causing computer gremlins.. id like to have some solid info on the problem if and when i tow it too the shop, if it is the tb i'll just order aftermarket and replace it myself but if its in the wireing.. well that harness is pretty scary looking, think i'll pay someone to look into that
I wouldn't think the TB would cause it not to turn over. Was this truck a flooded truck? We've seen a few on this forum that were flooded and had all kinds of weird symptoms. If I was you, I'd start with the starter voltage. Next, look at the schematics I've mentioned before, they are really good! They even show you where the connectors are. On the passenger side firewall, there are some connectors you may want to disconnect and re-connect.
its not that the tb specifically wont let it start, its more that the computer cannot communicate with the tb therefore the computer reads a fault and will not let the truck start, voltages all check out, as there is no cable to the tb anymore it relies on a potensiometer in the pedal assemble to relay data to the computer which in turn relays said data to a servo that operates the butterfly valve in the tb.. you could test this by unplugging the tb and cycling your key. you'll get the same red lighting bolt on the dash as mine... I had it fixed here on Friday, cost me around 650$ for the new tb plus diagnostics etc.. it just went down again a whoping 2 days later and left me stranded in a parking lot... not sure what the root of the issue is but so far its been 34 days ive had this truck and its chewed through its second tb....
as far as i know of the history on the truck i just found out its had a motor replaced about 40000 km ago, otherwise its been a one owner truck with no major issues.. high km's but dodge says it was in for all the recalls and regular service.. mechanically sound they said.... Im thinking i just bought a whole pile of nightmare
yes its a local dodge dealer, i'll see if i can get the specifics but the way i understand it its more the computer finds a fault in the tb and will not allow the truck to turn over, its not that it cant.. if the servo in the tb is cooked, how would it open the butterfly valve to allow air into the engine, therefore the computer will not even start the ignition process.. kind of makes sense in my head anyway, maybe i'm wrong but thats how the lead mechanic explained it to me.. like i say i'll see if i can get more info and post as i do
all i know for certain is that when i borrowed a different tb off a similar truck and plugged it in, away she went.. twice
also just curious but could a cold air intake and tb spacer have any effect on burning out the tb?
