The other day I did something really stupid and grounded out a jumper on a coolant snsor to keep the electric fan on (its 108 degress here in the desert)...one of the alligator clips grounded out on the engine. There was a puff of smke a puff in the dash and the the car cut out, will only run 5 seconds before the engine then dies, yet it will start and run every time for the 5 seconds.
My theory is that I melted a wire that has fooled the engine to think that the engines not running and the computer shuts down the fuel pump. All the fuses are intact and everything works fine for the 5 seconds its running except I noticed the tachometer does not work now. Any advice or where to start troubleshooting this would be appreciated.
Thx John
