Jag had ran great last Friday. Say morning starts and does after 2-5 second. Fuel pump and filter checked. Fine. Checked all fuses. Drained gas tank and had small amount of water and sand (never before cleaned) . Put high octane in with injector cleaner. Blew lot of white tailpipe smoke attempting to start.
White smoke almost cleared, but still doesn't start after 3-5 seconds.

 

P.S. Only had 4-5 gallons left in tank before we drained gas tank. Car had ran fine. No new gas had been pumped for a week. Car ran perfectly for 3/4 of tank.
