I have a 1991 Gmc Sonoma with the 4.3. I recently replaced idler pully and no more then a mile later my truck stalled out. I replaced fuel pump and i am still having issue I am thinking my injectors are bad but I am not sure. If i spray starting fluid into throttle body the engine will crank but only for a moment then it stalls out again. Is there anything else that could be causing this other then bad injectors? Fuel is being delivered to throttle body i can hear fuel pump kicking on i believe i am getting spark gonna test that tomorrow as well as replace injectors but other then that I am at a loss please help!!! I miss my truck..... update injectors were replaced and I cleaned throttle body and still no start looking for any advice or suggestions ecu maybe? 🤷
