If it starts and cuts off within seconds that usually is a security circuit issue whether key or fuse etc. But could be fuel mixture. Sometimes reading the code will help. In order to do a reset the memory capacitors have to be discharged, either by touching disconnected battery cables for 20 seconds or turn on headlight switch for 10 -20 minutes while battery is disconnected.

I have a 2007 Dodge Ram 1500 SLT with the 4.7. The plugs for the 4.7 have a reach of 3/4". I believe my mechanic may have installed the plugs for the 5.7 hemi which are 1" in reach. My truck went into the shop perfectly fine and came out with the engine knocking. Is it possible that the 1/4" difference in length caused the pistons to strike the longer, incorrect plugs hence, that caused the knock? The shop admitted to me that the wrong plugs had been ordered. When asked if it was possible that they may have installed the incorrect ones, they told me that the thread size wasn't the same. Well, truth be told, it is the same size thread. Thanks for any input! 2 Answers
