In December I overhauled my engine(420A). It was hydrolocked from a flood we had and i didnt check the intake tube before starting it a few days later and bent a rod. I replaced the pistons, rings, connecting rods, bearings, valves, water pump and timing belt. I also had the block honed by a machine shop and the cams and crankshaft checked, they were fine. I also replaced the starter, idle air control motor, throttle position sensor, and the camshaft position sensor. The car started up just fine and ran great for about a month(about 1000 miles). Then about 2 weeks ago the engine would shut off while driving but would restart usually on 1st try. Then it wouldn't start at all a few days ago. No Spark or Fuel. I have 48psi fuel to rail and iginition coil is good. I had no signal to coil. I changed out the Crankshaft position sensor and the car started right up and ran great. That was last night, then this afternoon it died on me again again no spark or fuel. I was just looking for some help on where to go next, could the CPS be bad again and if so what could cause a brand new sensor to go bad within 1 day?
