1988 Ford Thunderbird, fairly stock car. Only "mods" are EGR delete, and IAC block off plate, other then that that's all. It runs very strong for an auto car, but it haves this problem. The car will do it at random(warm or cold) the r/h cooling fan will come on when the ignition key is turned to the on position and if tried to be started the car will just turn over with no spark. I unplugged all of the temp sensors and the fan stayed on, unplugged the the fan and the car still would not start. But if the fan does not come at first the car starts first hit every time. I am stumped. If this is in the wrong section please let me know.
