Please help, I have a 1987 s10 blazer, I have put in a new fuel pump, filter, strainer, plugs, I am getting gas all the way through the lines but not in the tbi, I have changed the sprayers, some one told me it may be a sensor, but which one and where is it located? I was driving it and it was getting gas good but had some sputtering in it, it just quit on me and will not start back. Only when I prime it and then it wont get gas through the tbi to keep it running help I dont know what else to do!11

Are you getting voltage at the injectors? If no voltage then the injectors wont work, you should check out your cam and crank position sensors, you getting good spark?

You should have your cam and crank sensors checked. They controll spark and injector pulse. Sounds like you have no injector pulse so you should have those two checked.
Check the fuse and the throttle position sensor also.

How do I check those and where are they located? Some one told me it might be the brain in the distributer, what do you think? Thank you for your help.

Sorry but I dont think its the ignition module as it deals with spark. But you have that.

I dont know where the sensors are located on your car, even if I did I wouldnt know how to test them on your model. Plus if you change them they have to go through a relearn cycle anyways.
