if you replaced fuel pump i would look at backward wiring when replaced and i would start at the source of work if your vehicle was working fine before replacement then 9 out of 10 it will be your fuel pump wireing
sometimes when putting wireing back together the connectors have the missing clip and in turn you can turn the wireing in both directions now where positive is touching the ground on both sides of connector kris kross problem check your work this is crucial use a test light to find the right wires where they go

The power supplied to the fuel pump, ignition coil, fuel injectors and parts of the power module is controlled by the logic module through the Automatic Shutdown Relay (ASD):
The ASD relay is closed (allowing power to flow through it) when the ignition is first turned on. If the signal from the ignition reference is lost while the engine is running, the logic module cuts power to the ASD, which in turn removes power from the fuel pump,ignition coil, injectors and those parts of the power module. This causes the engine to shut down.
Failure of the automatic shutdown relay is often shown as inexplicable stalling or refusal to start. The ASD can be triggered by a broken wire or short in another place, e.g. the fuel pump. Hope this helps, and did you try to retrieve any DTC codes?? Be glad to help friend.

I understand that there is a relay box under the hood with 3 relays. Which is which I don't know. However if you are blowing the fuse TO the ecc relay, then the relay must be bad. This relay controls the spark.
