I have a really strange starting issue with a 1992 Ford Taurus with standard 3.0 Liter V-6 engine and 130K miles. The car has always run great but last summer developed a problem where it sometimes wouldn't start. Let me backtrack a moment. When the car is starting normally you can turn the ignition key to ON and you will hear the fuel pump in the tank hum for a second as it comes up to pressure. You then turn the key to start and the car starts. Last summer you would turn the ignition on and the RADIATOR COOLING FAN WOULD COME ON while the humming in the fuel tank didn't stop. The engine wouldn't start at all even though it cranked normally. After a while (sometimes a couple of minutes) the cooling fan would finally shut off and the car would start normally. After checking several things (spark and compression were both OK) I finally "fixed" the problem by going to a junkyard and replacing the integrated RELAY CONTROL MODULE (it has a big 24 pin connector going into it) that is mounted on top of the radiator (I replaced the original P/N F1DF-12B581-AA with a F1DF12B577-AA). Everything seemed fine and the car ran fine until last week when the car wouldn't start again. Once again the fan comes on but now won't shut off at all most of the time. On the rare occasions when it does the car starts as it should. Figuring that another junk yard module wouldn't be any better than the one I had I bought a new one from a Ford dealer (F6DZ-12B577-AA is the part number that Ford says is the current replacement). However, the new relay module hasn't helped at all and the car still won't start and the cooling fan comes on whenever the key is turned on. Any ideas? Thanks.
have the same problem?
