Hello,

Need little direction. I don't hear the fuel pump come on to put pressure into the system,  I also check to make sure that their was no pressure in the line. I check the relay, I believe it is okay. I was checking the power junction box for voltage, and did not getting 12 voltage where pin 86 connect too. I did get voltage where  pin 30 plug into on the power junction box. As far as checking the fuse, and fuse area. The fuse is good, but I can't check where fuse plug into very well. I try placing some wires in the slots, but I may have not gotten good contact on the metal to pick voltages.

I am thinking checking the wiring back by the fuel pump, not sure if I should check in different place first.

Any body have suggestions?

Thanks !

Bleed the fuel pressure off at the rail, then turn the key back on and see if it pressurizes again. If not, hit the bottom of the fuel tank, sometimes it will kick start the fuel pump. If this puts fuel pressure back into the rail, this may give you a little time to replace the fuel pump. It's hard to check the voltage on the fuel pump because it shuts down as soon as it is pressurized, so someone has to turn the key on and off while checking it at the same time.

You will only have power at the pump at two times:
1) For the few seconds when the key is first turned on.  And it will only cycle the pump for a couple of times then stop.
2) When the computer sees the engine is turning (cranking or running).  If the ignition is on, but the engine isn't turning there is no power sent to the pump.

There is an access plate on the trunk floor to get at the wiring and fuel pump easily. You don't have to drop the tank.

THAT is nice to know. Why didn't I know that already? I remember some of the others saying they were cutting holes in the floorpan to access the pump, but you are right, nobody ever did it with an Intrepid. Thanks for this tidbit of information.

Thanks everyone. I did know about the access panel, since I something chew on the wiring back there few years ago. I already check the fuel rail, for pressure and that confirm that the pump was not working. Is their any place to check to firm that the pump is getting 12 volts, before I go threw the access panel in the trunk?

Access panel gets you right to the connection, can't do better than that.

Hello Everyone,

Since weather been been nice I can work outside again. I found my problem. Found broken wire back by the fuel pump rather something chew on the blue wire. After soldering wires together my fuel pump is working. Now I just have get new battery since the cold weather did it in since was pretty old.

Thanks for help and suggestion.

Glad it was something simple.
