i just bought an 86 suburban with the 6.2l. i was playing around with the injector pump earlier and i got it working good earlier it had a small amount of smoke and a loss of power. i went back into it to adjust it as close to where it was to begin with as i could and now its getting no fuel. i dont know how or if i did but i believe the solenoid went out and will not start. anyone have ideas?? im gonna play around with it some more tomorrow and see if i can get it working.
