No power after changing gas fuel pump for 91 chev

I have a 91 chevy silverado 1500. I changed the fuel pump on it and after it had no electrical, not even lights. Nothing, Checked all the fuses and they were all good. I found that the negative to the engine needed to be reajusted and started for a minute then quit. Negative cable became so hot it almost melted. I changed the negative cable on the battery and regrounded it to another spot on the block, I checked all inline fuse links. Grounding strap to the engine. Changed the batteries. New connections on the batterys now no matter what I do I have a hot positive and a hot negative. Help me please.

Check starer cable make shur that not grounded to exhaust
also make shur that there is a short ground wire from the neg connection at the batt to the body
there should not be poer at the ground
start pulling fuses to find your circuit that is causing the short
that should help you isolate the area that has the draw or short

You have a short to ground.What that means is,you have a power wire...............that is grounding on the vehicle somewhere,or possibly back in the fuel pump.The fuel pump theoretically could be shorted internally causing the problem.It also could be a wire or wires back where you were working possibly got pinched.Disconnect negative battery terminal until problem is solved.

1999 chevy silverado ran out of gas


After you have the battery charged, you may want to check the fuel pump relay and see if the pump is getting power.
Its possible the pump is cooked from not having gas in the tank.
The liquid gas cools and lubes the electric pump.

How to change a fuel pump on a 2000 chevy 1500


The fuel pump is located inside the fuel tank. You can either drop the fuel tank and remove the pump or get 3 friends and unbolt the bed and then remove the pump. Once you have access to the pump, disconnect the fuel lines and electrical connections. Then remove the pump from the tank.

Well if theres power going to the relay but not out, then you need a new relay. If theres power in and out of the relay, you might need a new fuel pump. The electric fuel pumps inside the tank are actually lubricated by the fuel as it pumps it, and if it runs dry long enough, it can burn out the pump

Change Fuel Pump on 1999 Chev Silverado v8 2 wd automatic 2 door


well the pump is in the fuel tank and it depends if the tank is full or not if it is its very heavy and you will need a jack and 1 other person to help you there are two fuel lines to unhook and the electrical connector. When replacing it replace the entire fuel pump/sending unit and the electrical harness or you will end up having more problems also spend the extra 15$ and replace the fuel filter
