    It could be fuel pump on its way out. Had similar syptoms volts say nothing its the presure test on fuel that would confirm that. Apparrently should never let fuel below 1/4 tank as pump is cooled by the gas. Do not buy cheap after market pump as you will be doing it twice like I did.

    i had the same problem itrs your crank position sensor i guarantee it

  • Jim Draper Jun 17, 2013

    To candctruckin: I agree that is the suspect problem. I do not understand how this happens with the delay in time almost like it just has to cool down. Is PN# 0021539228 the right part number, and will a Standard Motor Products # PC393 work? Your help is greatly appreciated.

    We have replaced everything in the electrical (including ECM), Fuel, and Emissions systems except the fuel pump relay, and the crankshaft sensor. We are leaning to replacing the fuel pump relay, and possibly the fuel shut off valve if it has one. Trouble: Vehicle runs and drives great until it warms up and then it just shuts off with no warning. Wait an hour and a half to two hours and then if will start and run. Then when it warms up it dies. Nothing so far has made a difference. Any suggestions?

    candctruckin: I agree that could well be the problem. ?Why or how?

  • Jim Draper Jun 17, 2013

    Is PN# 0021539228 the right part, and will Standard Motor Prouducts PN# PC393 work as well? Can you tell me where it is located. I have two conflicting stories. One says the it is located on the bell housing behind the oil filter (Tech says it is not) and the Tech says it appears to be on the drivers side of the bell housing. Any help?

1995 trans sport van new fuel pump, won't start

If the pump continued to run after shutting off the car you fuel pump relay was probably staying latched. I would replace the relay as well based on your info. Along with the pump the fuel filter should be replaced too and fuel pressure should be checked. Make sure your ground is good also.

How to install fuel filter&pump

  • De-pressurize the Camry's fuel system. With the gas cap open (to release pressure in that location), open the fuse/relay panel under the hood and remove the relay labeled "C/OPN." Start the engine and let it run until it stops. Disconnect the battery's negative cable.

  • Detach the rear seat from the car. Lift up the front edge of the seat bottom cushion, disconnect the mounting bolt underneath and remove the cushion. Pull up the seat back locks, flip the seat backs down and remove the mounting bolts.

  • Remove the service hole cover from the floor under the seat concealing the fuel pump/sending unit.

  • Disconnect the fuel line and electrical connectors from the fuel pump unit. Remove the retaining bolts and withdraw the unit carefully out of the fuel tank.

  • Release the clips on the fuel pump assembly's plastic support with a screwdriver to remove the support. Then pull off the rubber isolator, remove the fuel sock filter and disconnect the electrical connector from the top of the assembly. You can now withdraw the fuel pump from the housing.

  • Connect the new fuel pump into place on the assembly housing. Reassemble the fuel pump/sending unit in order, from the electrical connector to the fuel sock filter, rubber isolator and bottom plastic support.

  • Place the pump unit back within the fuel tank and reattach the bolts. Reconnect the electrical connectors and the fuel line. Reattach the rear seats.

  • Replace the "C/OPN" relay, reconnect the negative battery cable and fill the fuel tank if it is empty.

  • Pressurize the Camry's fuel system by turning the ignition on for a couple of seconds. Then turn it off for ten and repeat this five to ten times.

    How to replace fuel filter on 1995 jeep cherokee sport?


    it IS on the inside of the drivers side rear frame. In between the back wheels and the gas tank. You have to the pressurize your fuel system first unless you want gas every where. Take your fuel pump relay start the jeep until the fuel in the lines get used up. then put your relay back after you disconnect the battery, than take the filter off, put the new one on, and then hook your battery up and start the jeep. it will run odd for a minuet but after it builds the fuel pressure up it will be smooth again.

    Good luck.

    Oh and don't smoke while your doing this!! :

    try fuel pump located under back seat, it could be the sending unit, which is part of the fuel pump.
