Help!! Burb won\'t start!!! Trucks been running great.All of a sudden it turns over but fails to start.Plenty of spark.I take the fuel filter loose and no gas flow with the key on.Well she has 174,000 miles so she's due for a fuel pump.I put the new one in and turn her over fires right up.I let her run a bit and then shut her down.This morning again she won't start but turns over.Now i tested the old pump and she worked fine connected to a battery and the new one appeared fine also.The directions says low oil pressure or a faulty pressure switch can cause the fuel pump to shut off due to the oil pressure. /forums/images/graemlins/confused.gifThe wiring diagrahm does show the fuel pump wiring going thru the oil pressure switch.My manual doesn't even mention the oil pressure switch.Where is it at???Does this sound like the problem??Any advice??
