Hi, I replaced my fuel pump in my 95 JGC after it blew 2 relays, The pump was bad. It ran great for a week now itis blowing relays again. Any suggestions as to why? Thanks. The fuel pump is a new Chrysler unit.

I would check the continuity of the wiring for intermittent shorts or bad grounds.

I believe it may have been a low voltage problem. The guage was dipping to almost the 13 volt range when the heater or any other accessory was used. It went into auto shutdown. I replaced the alt and it seems to be running great again.
