Do you mean pressure? they sell a kit to check pressure. if your engine is not ticking then it is probably a bad sender.

My 2002 GMC Yukon Denali's fuel guage goes up and down sometimes. It is not always reading correctly. Is this a sensor problem or a fuel pump problem.

Most likely the rheostat on the float is bad. Unfortunately, this is part of the fuel pump and inside the fuel tank.

remove the engines oil pan and you will see a screen attached to the oil pum. Remove all and replace both items. They simply bolt on. The tang to the pump is inserted into the distributor shaft which is easy to slide in place. Have all areas of the gasket areas clean before reassembling along with a new oil pan gasket too

I have a 2002 Yukon/Denali with an oil leak

I had the same problem with my 87 gmc year ago but if it is the same set up and I am assuming it is because it is exactly the same problem i went thrugh then when you take the filter off look and see if there are two bolts up in the assembly and if there are it probably is the seal, mine worked there way loose and a simple tightening fixed the problem, otherwise you will have top replace the seals

Water pump for 2002 Yukon Denali

Your water pump can last an indefinate amount of time as there are no rules on how long this may or may not last.At this juncture I would check for any play or lose feeling(or roughness) in the shaft with the belt off and inspect for any signs of weeping through the bottom "weep hole".If it feels tight and no excessive coolant trail appears from the bottom hole,I would personally "keep on truckin" as a failing pump will exhibit these an other signs of failure before it becomes a major issue....
