you say you've checked the relay but is it possible that the fuel pump
relay has high resistance across the contact points... sounds plausible
esp. if the old pump really was bad, could have been drawing very high
current causing an arc when the points closed/opened. If a relay for
your vehicle is not that expensive I'd try it.

good luck,
