And now the only way I get the starter or fuel pump to work is to use jumper wires in place of the relays and I don't seem to be getting any signals from the computer (using the code scanner and the turning the key off to run 3 times).

It has been a little bit since the last post. Is your vehicle still giving you the same problem and if so can you provide an update or if it is fixed now, please let us know.

I took it to the shop who charged 500.00 and said it was a broken wire from the ignition to the pcm. Problem is the fuel gauge still doesn't work and if it was the pcm I would have gotten a no link message from my code reader when I tried to read it. So as it stands the vehicle runs but I don't know for how long till it decides to go on me again.

On the fuel gauge...I did find a TSB that you could check on a bad wire connector under the seat.
If that isn't it then it is probably the sender on the fuel pump. If it were me....if I went to the trouble to drop the tank....I would change the entire fuel pump.
Last, you may have some recalls on your vehicle. The dealer may fix these for free. Please contact the dealer service department, give them the VIN number of your car and have them check on these to see if they apply to you.
Fuel System - MIL ON DTC Set/Driveability Concerns
MIL illumination with Leak Detection Pump (LDP) Diagnostic Trouble Code (DTC), fuel gauge reading inaccurate, fuel pump not working, and/or engine run-on.
Using the Mopar Diagnostic System (MDS2) and/or the Diagnostic Scan Tool (DRB III) with the appropriate Diagnostic Procedures Manual, verify all engine/transmission systems are functioning as designed. If non-LDP related DTC's are present, record them on the repair order and repair as necessary before proceeding further with this bulletin. If Leak Detection Pump DTC's are present, and/or owner describes an inaccurate fuel gauge or engine run-on, inspect the C308 wire connector located under the rear seat cushion for the presence of moisture and/or corrosion. If moisture/corrosion exist, perform the Repair Procedure.
POLICY: Reimbursable within the provisions of the warranty.
Labor Operation No: 08-90-73-90 0.8 Hrs.
FAILURE CODE: P8 - New Part
1. Disconnect and isolate the negative battery remote cable.
2. Locate and remove the existing C308 connector by cutting the five wires (LDP equipped)/three wires (non-LDP equipped) on each side of the connector. Stagger cut all wires on the harness sides at 1/2 inch intervals.
3. Remove 1 inch of insulation from each wire on the harness sides.
4. Stagger cut the matching wires on the repair connector assemblies in the opposite order of the harness stagger.
5. Remove 1 inch of insulation from each wire on the repair connector.
6. Place a piece of heat shrink tubing over one side of the wire.
7. Spread the strands of the wire apart on each part of the exposed wires.
8. Push the two ends of wire together until the strands of wire are close to the insulation.
9. Twist the wires together.
10. Solder the connection together using rosin core solder. Do not use acid core solder.
11. Center the heat shrink tubing over the joint and heat using a heat gun. Heat the joint until the tubing is tightly sealed and sealant comes out of both ends of the tubing.
12. Repeat steps 6 through 11 for each wire.
NOTE :ALL CAVITIES IN THE SIX-WAY INLINE CONNECTORS, ON BOTH SIDES OF THE CONNECTION MUST BE FILLED WITH TERMINATED WIRES. ANY WIRES THAT ARE NOT USED MUST HAVE THE NON- TERMINATED END SEALED WITH HEAT SHRINK.
13. Re-tape the wire harness and connect the connector halves.
14. Connect the negative battery remote terminal.

When I had the tank dropped I did replace the full assembly (fuel pump, tank sending unit, etc.) Where is the C308 connector mentioned in that tsb I seem to have the same and reversed symptoms. (The fuel gauge is random, but instead of running on the vehicle dies on the road) I am thinking a bad connection thru the plug its mentioning removing " may" help if not then I am where I am now and resolve a tsb on my car
December, 6, 2008 AT 9:32 PM
Sorry - read right through that.....yes.....you did replace the pump.....
That TSB says it is located under the rear seat: inspect the C308 wire connector located under the rear seat cushion for the presence of moisture and/or corrosion
I have attached a pic.....

I didn't find a plug to replace but there is quite the pool/puddle under the back seat. But I think I am going to try and dry out the puddle as much as I can and see if I can find where the plug used to be and see if there are any breaks in the wiring or insulation. I really really appreciate all the help I am recieving from you guys. I have been repairing my own vehicles for 15 years or better and yall are pointing out areas that I had never thought of.
December, 6, 2008 AT 10:16 PM
WOW. I think I found the c302 plug it has 3 wires on one side and 5 to 6 in the other side. The side with 3 has corrosion coming out of the ports on the plug and 2 of the wires are bare and shorted enough to melt half the plug, the other side has the same corrosion coming out of the plug and wires corroded all the way through. I am about to do the bypas mentioned in the tsb. But I am pretty sure this will solve the problem. I will keep yall posted with how it runs.
December, 6, 2008 AT 10:30 PM
Do you happen to know which wire goes to where there are 3 coming in 6 going out
December, 6, 2008 AT 10:33 PM
Yes please do.....I thought the TSB said connector C308......I have attached that info.
I am showing 302 by the door /body area........
Interesting - if I remember the TSB it does talk about corrosion etc.....
If you do find the wires/plug....be sure to check all over for that corrosion....that could go deep into the wire and be causing problems.
Though it said under the seat......what about under the car......where the seat is?
I just checked another manual and it says C308 is in the trunk area.
I have attached another pic.....it looks to me like the wire colors are Dark Blue, Dark Green, Orange, Dark Green w/White Tracer, Black, and Light Green w/ Black tracer.
