Yeah I've got a good OBD2P0303 - Cylinder 3 Misfire
OBD-II Trouble Code: P0303 Cylinder 3 Three Misfire Detected (obd-codes.com)
I have a good OBD2 reader. I got the code. Misfire on three and I changed cylinder 3 coil pack and plug. Everything worked fine and the code disappeared but then my truck stalled right after the fact? I pushed the Schrader valve on the fuel line because it sounded like it wasn't getting fuel. There was no pressure in the fuel line at all? I just was wondering if it's a coincidence or they could be connected?P0303 - Cylinder 3 Misfire

That is what I am guessing. I think I have been dealing with this for over a year. I had some issues in the past with fuel boiling in that fuel rail. Apparently that 3.7 l never had a proper purge valve. So instead of the fuel going back down in the tank it stayed in that line and cooked? Another Chrysler faux pas haha. Thank you sir I appreciate your input.@Fred Zeplon ;
Discalimer: I'm not a mechanic, but, here is my observation;
A code P0303 may mean that one or more of the following has happened:
Faulty spark plug or wire
Faulty coil (pack) Faulty oxygen sensor(s)
Faulty fuel injector
Burned exhaust valve
Faulty catalytic converter(s)
Running out of fuel
Poor compression
Defective computer
If you look at the possible causes, one of them is "running out of fuel" which is essentially what would be happening, if your fuel pump died and is no longer pumping fuel to your fuel rails. Then you couple that with your own observation, that there was no pressure in the fuel line at all.
So, I'll go out on a limb here & say yes, those 2 issues could very well be connected.
It could very well be the result of a bad fuel pump.
Absolutely. I don't have time to do it until Sunday or Monday but I crawled underneath and oddly, it looks fairly new and clean all around the tank. My buddy replaced his on his 07 Hemi and it was complete rust show. He had a custom make new braces.No problem FZ, let me know your results when/if you replace the fuel pump, if you don't mind.
Ok... here's the update...lol. Bought the fuel pump...no too difficult to drop the tank. A couple of recommendations are...try and get the fuel out beforehand as I had 3/4 of a tank! Dropping it was not to bad but trying to reinstall it was nuts. I went and bought a pump and drained it. Much easier. Also take the driveshaft off at the rear...and remove the spare tire!!! The filler hose on the tank end was essentially melted to it. Giving myself more room with spare gone allowed me to get a better attack angle....lolNo problem FZ, let me know your results when/if you replace the fuel pump, if you don't mind.
