fuel filter symptoms

Recently, I have had my relays burn out a few times when I am driving down the road.

Sometimes the Jeep won't start at all but turnover and then all the sudden it will. Is changing the fuel pump/fuel filter the remedy for this??

I will add the fuel relay was bad both times and for a third time it was bad. What is the cause for this?

Wires may be crossed somewhere a long the line. That'd be the first thing I would check for. As far as if the pump is bad -- have someone listen back by the tank while you turn the key to "run" and the pump will whine as it primes up. If not it is probably bad. I wouldn't think a bad pump would sometimes work and sometimes not though. Sounds more like a wiring issue in your case.

I am hard pressed to remember when the last time I did anything under the hood besides spark plugs for any wires to ground out.

I was thinking if the fuel filter was clogged, the relay may experience an overload and burnout. I know the fuel pumps do work BUT the relay burns out shortly after it is replaced.

But no matter the running condition of the pump, your relay should not be affected. Pump either works or doesn't. And there is no seperate filter on Wranglers. If you suspect that to be the issue you'd have to replace the whole pump anyway.
