swapped horn and fuel relays to no avail.It will almost start at times and seems to be running at 25rpms but won't catch up.When it finially does crack operates perfectly no rough idle or hesitation and will start back normally.

Another way to test for a bad or continuous running fuel pump is to Disconnect the Battery? It should shut off immediately !
