Default 1995 Saturn TC not getting power to fuel pump relay

My 1995 Saturn Twin Cam is not getting power to the fuel pump relay in the front and back panel. Please help

Things I have tried:


Checked the fuel pump relay no power, checked the circuit going to the relay there is no power. Checked the relay no power. Checked the 30 Amp IP Batt fuse for power on both sides and they indicated power (Worked). *

REWARD EXCELLENCE!

If you pull the 30A Fuse you should have no power on one side of the Socket. Check continuity from that side to the Pump Relay Socket. Maybe bad connection somewhere.

Does the dome light work? Does the radio lose its memory? Does the Chime work? If the answer is NO then the problem is at F-5 on the black 68 pin plug on the forward rear of the I/P Panel. Large red(pink) wire. Burned connector and pin.

That red(pink) wire is a direct connection to the IP BAT fuse in the UHJB. If you have decided it is the problem fixing is usually not that bad. You disconnect the battery negative terminal and then unbolt the center bolt in the black 68 pin plug. Once the bolt spins free grab the wire bundle and wiggle it all the way out. take a small chunk of scotch brite and clean up the F-5 pin in the panel. Just get it clean on at least one side. To fix the connector in the plug you remove the blue connection assurance clip that is on the side of the plug. pull the one that holds F-5. Once that lock is out you look at the face of the plug and locate F-5. Look closely and you will see that one side is rounded under. On that side you insert the end of a flat type of bobby pin under that rounded side and when it stops you can gently pull on the back end by the red (pink) wire and it will slide out when unlatched. If it does not slide right out slightly twist the bobby pin to lift the latch. Once out re-spring the latch slightly and clean up the section that slides over the pin. Use scotch brite instead of any abrasive paper. Reassemble and reconnect negative lead at battery.

Thank you for your prompt response. I'm helping my grandfather work on this car and using this online forum to hopefully fix my issue. He doesn't have any knowledge of any wiring that is too technical so your response scared him away because he could not understand. I am gathering as much information of his troubleshooting as I can.

Current issue:

Nothing on the inside of the car is working which includes dome light, power door locks but the windows work, windshield wipers, turn signal and headlights.

It seems that when I pulled the center console out from underneath the radio there seems that several wires have been tampered with or fixed in the past. There is only one wire after checking there that is getting power and it's a purple wire.

REWARD EXCELLENCE!

You really do not need to disembowel the center console and doing so can induce problems. Disconnect the negative battery terminal before you melt something.

Is there an aftermarket radio installed in the car?

If nothing else take pictures and post them as attachments. The wire from the battery is called red but looks pink to most people. It is a large diameter wire that is 5 spaces up on the black plug and against one of the vertical edges.

If the insider of the car is dead then this is the problem so the connector has to be disconnected and inspected. take pictures and post them. I can not give you good pin numbers as I do not have a 95 drawing to reference them from.

REWARD EXCELLENCE!

The problem is on the BACK of the fuse panel, at the connector that is closest to the engine. It is reached from the drivers side of the car by getting down on the floor and looking across the hump to the panel back.
