I have a 1991 gmc sonoma with 4.3 and I recently replaced idler pully and no more then a mile after replacement my truck stalled out. Immediately after replacing pully truck idled weird for a moment so I shut off the engine and restarted the motor. I took it for a test ride around the block and it seemed to be driving great as soon as i pulled back up to the shop the engined stalled out and I could not restart the engine. It seems like my fuel is being delivered to throttle body as i have replaced fuel pump and i am still having the same problem. The fuel lines have gas at the throttle body and i can hear fuel pump turning on . if I spray staring fluid it will crank but then it dies. I dont know if it is bad injectors or if its something else. About2 weeks ago i installed a throttle body spacer not sure if that has anything to do with this but I drove the truck daily and it was only after the pully install that this issue began. Please help i miss my truck
