Hi Everyone,

I have a 2007 Ram 1500 Sport 5.7L 144k miles and when I hit a bump the truck dies. Doesn't die slowly, but as if I've turned the key to OFF. Then it will just endlessly crack over, and Check Engine light along with a (lightning bolt symbol) icon will come on and I wont be able to get it to restart. If i disconnect the battery for a while and clear codes, it usually starts right back up and runs fine, until i hit a bump again.

Checked all fuses and connections and I can't find anything wrong. I've replaced the throttle body and TIPM and still not working. Going to replace the crankshaft position sensor, because it's cheap and easy. Anyone have any ideas? I do have an OEM remote start that was added at the factory, and my key is a reprogrammed aftermarket key. Key has worked great for years.

Feels like it a fuel or ignition problem.

Thanks,

Tony

 

Just curious if you have checked the wiring? Because you said it happens when you hit a bump which would tend to lead me to believe you have a wire shorting out. I Know when I had a problem somewhat similar to yours it was a wire inside the alternator. I would take it to the parts house and it would test fine put it back on the truck drive it down the road my truck would die. 3 times to the parts house and it checked fine each time I finally bought a new alternator and it runs like a dream thats been 2 years ago. I am assuming there was a loose wire inside the alternator causing the issue.

 

what are the codes ? might be a short or failing sensor of some type also could be fuel pump ,,but codes may help if you can post them
