If it won't restart, determine what's missing, the engine needs three things to run, Spark at all plugs, gas to all cylinders, and compression in all cylinders, tho an engine may run lacking one in one cylinder, it won't run very well!

You can check the relay in the under hood fuse/relay center.

The fuse relay is brandnew along with fuel pump, fuel filter, and the ecu but I pulled the ecu from a junk car but I really dont think that is the problem.
