How to change 85 Riviera fuel pump

SOURCE: 1996 suburban random misfire or

i would check the fuel pressure first if it is in the good ranges then your pump is good. have you checked your spark plugs and wires? if not i would, if bad replace. otherwise i would have the ignition coils checked to find out if they are working correctly. that is all i can think of. good luck

If the area under the carpet doesn't have an access panel, you can use a dremel moto tool with the small grinding wheel attachment to cut one out. I believe the cut goes inside the middle humps. (You can see humps running down the trunk area.) Do a web search for the exact location. After you do this you will have to put in a metal plate to cover it. What i do is i cut out 3 sides and not the 4th, then i bend it up and over, then bend it back.

The location of the pump is on the left hand side of the engine when standing at the front of the car.
You will see (if you have aircon) two belts.
If you stand to the side of the car to look at the belts.
From memory the inner one (closest to the engine) drives the aircon compressor.
The outer one drives the water pump, you will see the pump belt wheel towards the back of the engine.

Getting into the pump is a bit tricky.
I basically unbolted the engine mount from the body which then allowed me to jack up the engine as I needed it to give me space to unbolt everything until the 3 water pump bolts can be seen.
Just make sure you know which bolts go back where.
From memory there were about 20 bolts to undo before I got to the water pump.

Aircon compressor bracket bolt I only loosened them from the engine not fully removed, the same with the alternator I only removed the adjusting bolt to remove the belt.

Oh I just thought of something to do before you remove the tension on the belts... loosen slightly the 4 small bolts that are on the wheel that bolts onto the water pump.

I think the only size sockets and spanners I used were 10, 12, 14 & 17.

It took me around 2 hours to get it all undone, and close to the same to put it all back together with the new pump.

It was kinda straight forward as you can see what you need to unbolt because you know what bit you need to get into.

I hope this helps a little, I am not sure if it is clear in the way I have written it. But feel free to ask any questions.
