You didn't state if it was fuel injection or regular carb type.
If fuel injection, you have to drop the gas tank. Undo bolts on tank straps, lower slowly, disconnect the fuel lines and the wire connector for the pump. Make sure surface is clean, take a screw driver and hammer and tap the pump assembly locking ring until it's loose. Remove pump assembly. Installation is just reverse.
If it is carb type, the pump is on the drivers side of the engine.
Disconnect the fuel lines, take off the two bolts, remove pump.
To install that pump you need a pair of needle nose pliers to hold up the push rod while you are installing the new one. Hope this helps.

I need instructions on how to replace a fuel pump in a chevy sierre 2500 truck.


Those are pressurized pump in the fuel tank. You should have a inspection access plate on top of the fuel tank(s). If there is more than one tank be sure the relays and the system to change over tanks is working properly. First thing starting it , in the morning , turn all out side noise off, turn key to on position just short of cranking the engine over ,and you should be able to hear the pump in the tank , making a low growling noise , if it is working propery , this will last about 30 seconds while the pump builds pressure.

Fuel pump wiring diagram 1988 chevy truck


I personally have 1988 GMC truck and had to replace the fuel pump. I found all the info including wiring diagram in a haynes repair manual. These can be purchased in most automotive parts stores. Something I found interesting is that the fuel pump's operation works through the oil pressure switch, located by the distributor screwed into the engine block. If this switch is stuck or sticking it will affect the fuel pump. Replaced a good fuel pump for nothing! The truck had sit up for awhile and the ground wire connections had to be cleaned as well.

I have a 1988 chevy silverado 5.7 ltr and it will not trun over, what other option do i have besides replacing the fuel pump


Yes typical problem and know about the pain in the #$#$ about getting the tank down.

The relay is under the hood and in the relay box. Quick check the fuel pressure on the injection rails.

Yes you could add an inline fuel pump to the line and see if that would create enough pressure. I do that on my race cars.

Engine cranks excessively before engine starts,even after warmed


Check your EGR valve make sure that is working properly, if it is then go to the fuel pump, just a cheaper fix to go after the EGR then the fuel pump
