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


Glad you found the problem.

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
