ENGINE STALLS

1987 GMC S15

Electrical problem
1987 GMC S15 6 cyl Two Wheel Drive Automatic 16000 miles

My truck starts and when I turn the headlights on it stalls the engine then it doesn't get fuel after that what is wrong with it?
My heater is acting up also when I turn the fan to high the service engine light flashes and I hear a click under the hood and the fan wont blow on high only when it wants to what could be the problem there?

Clean all your grounds that you can find, eng to batt, body to batt, etc. Sounds like you are losing power because of poor grounds. Also make sure your battery isin good condition, if it 's not it screws up the computer.
