Ole Trusty won't start. My 03 2500 4x4 with 184k won' start. Last week, it wouldn't start after I moved it two hours prior. I replaced the fuel filter, (way overdue) and after purging the fuel system, finally got her started. It's ran fine for the last 3 days. Normal day yesterday, ran fine, parked it last night, no abnormal running, spitting, NOTHING. Went to start today, nothing. turns over but doesn't even try to start. I removed the filter cap and pulled the filter again, the canister if full of fuel. I appears to be clean and no water. I'm stumpted. Any one have any suggestions?
