Cladiesel

Looking for some help. I have an 87 2wd pickup that has a new engine and transmission in it. It ran fine for the first year then started having issues. Started with rebuilding throttle body with new injectors. Then put in a new distributor with a new coil. New fuel pump and filter. Truck doesn't even idle. Starts up and shuts down. Passenger side injector sprays when it wants to. Changed injectors again with same result. Installed new chip in ecm and same results. Checked and replaced all grounds. Just tired of putting money into it with same results.
