2000 dodge neon starts for 2 minutes then stalls

Possible fuel filter check your fuel pressure if you go to my website and fill out a form I can send you some diagrams and specs Autorepairtips.net

i forgot to mention that a month earlier the car was running hot and was leaking some coolant. mechanic says it was a waterpump leak so i added some stop leak that seems to have stopped the leak im hoping its a fuel filter or crankshaft senser not a waterpump timing belt issue.

also im getting a 1684 with the 0320. funny thing is when i swapped the battery to test if it was the battery the 0320 code is not showing all the time when i do the key code test . only the 1684 is constant in fact the 0320 did not show yesterday or the week ago when i swapped tested the battery

watch out adding stop leak, if your radiator has any slow flowing sections i have seen stop leak clog them up and your radiator won't flow right. P1684 is only a status which indicates that the PCM memory has been cleared within the last 50 ignition cycles and does not indicate a problem.
