The Blazer has a new fuel pump, filters, plugs, wires, distributor, coil, ignition module, the whole ball of wax. Once I do get it started it will start all day with no problem until sitting all night. Then it is hard to start again. I have 65 lbs of fuel pressure so it can’t be that. I brought it to GM and he put it on the computer and nothing came up. He said let’s start replacing parts and see what we come up with. At the money it would cost to find the problem no way.
