I have a 1999 eldorado that my son drives on near empty. The car was sitting for about 2 weeks and we went to start it one day using the remote starter. The low fuel sign was on and it ran for about five minutes. I thought it was out of fuel so I added about 3 gallons. all it does now is turn over won't start or seem like it wants to start. I tried listening for the pump to come on but hear nothing. I took off the fuel filter to replace it and a very little bit if fuel came out. Before I spend 300 dollars on a new pump is there any tests that i can perform to make sure that this is the problem. Also is there an access door to the pump like on the Seville. I know the tank is more forward and is not under the trunk.
