I have a 2001 dodge stratus rt with the 3.0 I have replaced the distributor the cap and rotor coils and pulgs and wires as well as the crankshaft sensor knock sensor and cam sensor and the car still only starts for about a minute and then cuts off and will not start for at least 30 minutes it gets fuel even when not wanting to start just no spark what else could it be and the car runs prefect for the minute it does run?

I found the problem my lower timing gear or crankshaft gear depending on what you what to call it was broken the 2 roll pins that come out the back side that goes through the metal plate to count timing seared off so the plate would not spin correctly and would not count time replaced the gear put everything back together and is running prefect

Im trying to find help replacing the seals on the crankshaft. The one that's bolted on has rotted out but all the basic videos just show the o-ring one and I cant find a car specific guide
