So what does the fuel spray from the injectors look like? The 2 injectors should spray a nice cone shape mist, no dripping at all. Possible fuel regulator may need to be rebuilt in the TBI.
Thank you I completely forgot about the regulator I'll replace it and repost if it make a difference or not
I replaced the regulator but unfortunately it still shuts off any other suggestions anything will help thanx
Well you could have the ignition control module tested, and check the two wires in the distributor from the pick up coil going to that center piece. Gently pull on them, they will brake right there.
Thanx rowefast it was the Ingnition control module
Julio did yours bogg out when you would drive it? I think I maybe have the same issue
Yes it did but for me it ended up being my egr valve I didn't install it right and one of my vacuum lines was melted and no air could go through
I have a 87 s10 blazer and I've replaced everything and rebuilt the tbi I can not figure it out for life me can some one help me it cracks fine just won't start Everything is new. Just figure it out
Mine boggs out when under a load like going up a hill I checked the fuel pump it is still kicking strong when I got the truck it sat in a feild for 10 years most of the vacuum lines are gone. I am gonna buy some vacuum line and hook them up is that the problem?
