2007 honda rancher 420fm 4×4.

this machine was running great then began to sputter out and die once running hot.

I replaced the fuel pump filter. the fuel pump canister was filthy.

Now. after fuel pump back installed. Turn the key on and try to start. FI light flashes non-stop. while key on and flashing you feel pulsating down at the fuel pump relay. I replaced that too. Still same issue. machine will not start. FI light flashing non stop and will not allow to run.

ANY IDEAS can help. thanks.
