My 1994 Cadillac Fleetwood Brougham ran fine , found it leaking slowly out of my water pump. So ordered a water pump ,Optispark, and a harmonic balancer . replaced all the parts and it wouldn't start. I left it alone came back my son had started it , and drove it about 30 feet so we could flush out the radiator, via heater hose line. We did have a small leak around the thermostat hosing ,because I removed it for my first flushing, drained the water added radiator flush and was started with flush you buy , was going to put a few miles on it flush it again . Then wash it out , fill with antifreeze. PROBLEM : car just shut off and want start, its more than likely the spark , or the new cheap Optispark any help here? May have gotten a small amount of water on it, but not a lot. A little water shouldn't affect it , because a big puddle could do worse.Any tips maybe try to see if I'm getting fire?
