Truck won't start
Drove my 2003 dodge 1500 4.7l yesterday had no problems. Got in it this morning to go to work and it wouldn't start. Turning over acts like it's not getting gas? IDK I need help
Can the ground cause my 2003 to turnover but not crack? Could really use your feedback!

The MAP and oil sensors are part of the 5v reference system. I have seen instances of failure (short) in one 5V system throw codes in other 5V systems. I think that is the case for you now.
Some other 5V systems: crankshaft and camshaft sensors, O2, TPS.
The next steps I'd recommend for you: option 1- troubleshoot the system to find the faulty sensor by checking reference voltage. You need DVM/probe to do this. Check ref voltage at MAP, if it is not 5V then disconnect the sensors I mentioned one by one until the voltage goes to 5. The one that sends MAP voltage to 5 when you disconnect it is the faulty sensor. Option 2- replace the camshaft or crankshaft sensor, whichever is easiest for you to replace, then try to start the truck. If it doesn't start then replace whichever (crankshaft or camshaft) sensor you didn't replace the first time.
I am 90 percent sure it is crank or camshaft sensor problem.

I will try that Thank You I'll let you know how it goes. I love my truck and hope it works lol
