Have a 97 tarus, was running fine, parked for a couple of hours and when I came back it wouldnt start, checked all electrical starter cranks have spark and appears to have gas, by all reasonable measures this engine should run please help
Recheck spark by putting a plug into one of the plug wires and place on valve cover, crank engine and see saprk in that plug. check fuel pressure during cranking to verify fuel supply. If you have no fuel pressure check fuses and fuel pump relay, in fuse box and power distribution box under the hood. If all are good check for power at the fuel pump connector with the key in start position, in run position the power will only be there for about 5 seconds, you are correct with fuel and spark it should run, let me know what you find

We had a problem like this in our 97 Camaro with the V6. It would run fine until my wife went somewhere with it, parked it and then wouldn't restart. When it would sit for about an hour then it would start again. It turned out to be the crank position sensor, when the electronic part of it got hot enough it couldn't sense correctly and tell the computer how to time the spark. All it would do is crank without firing. So once we had that sensor replaced it ran good again. Good luck I hope this helps! I'm on to the next problem it's having, an occasional battery drain and a radio and electric windows that die when they want to and come back later. BuzzieTN
u may need to have ur computer reset, u dont say if u have any warning lights on the dash. other fuelling system sensors tie in with the air flow sensors. plug ur diagnostic port in at a garage and see what fault code reads.
There is a lot more to the cooling system than the radiator and thermostat. 97 and 98 taurus' are prone to cooling fan failure. They also have issues with the coolant turning to a rusty colored sludge that can plug the radiator, and it let go long enough can eat the fins off the impeller in the water pump even cause it to break free from the shaft.
Do you have the "firing order" correct? In other words, is each spark plug wire going to the same cylinder it was on before you changed the plugs? If you have done nothing else but changed the plugs then this is the most likely problem.
If when you try to start the car it backfires through the exhaust or backfires through the intake. Then this " IS" the problem. Good luck.
