2002 Yukon fuel injection service needed?

depending on the year model.. plugs and wires distribitor cap and rotor. air filter. and defently a fuel filter. the more often you change the fuel filter the longer that high dollar 300.00$ fuel pump plus labor. will live. hope this helps.

Check the fuel cap!! If the vacuum relief is not working it can impede the fuel flow and cause the engine to shut down or not restart after a stop. Waiting usually gives things a chance to stabalize and the engine will restsrt. When this happens again try loosening the cap and see if the engine will restart.....If it restarts immediately, REPLACE the fuel cap..Do Not leave it loose because this will cause other problems. If it is not the fuel cap the problem may be the filter, the fuel pump, or aome other fuel system malfunction.

Yes, you will need to remove the fuel tank. Replacing the fuel pump is a pain in the *** if you've never done it before.

Gas Filter? Then scan tool on it,to look for codes set when check light came on. Most likely a senor is old and out of range.

you don have to do much to that gmc as long the coil is good, just replace all 8 spark plugs, air filter and basic oil and filter change; use good brands of oil, such as castro, mobile, shells ect. if your the original owner and have high miles and never have replace thermostat, I would go ahead and have it done, I would not wait until it fail and over heat on you. if you have done lot of pulling with your vehicle and have 75-100k mile, have your transmission flush with new filter, it will give the tanny life last a bit longer.

the owners manual will have a list. most of the time when people are going to sell or trade in a vehicle, they do NOTHING maint wise. I would start from scratch and replace ALL FLUIDS, trans service ,fuel filters spark plugs ect.

coolant flush and fill.. differential oil changed out ( assuming you have done trans service already also ) .. driveline (u-joints) and steering linkage lubed , fuel filter(s)..and all belts /hoses inspected ... have fun :)

Denalis are famous for clogged fuel filters. Change the fuel filter first and see what happens, Get the code for the check engine light. It could be you have a clogged EGR ports. Remove EGR valve and clean out the ports, replace with new gasket and see what happens. Advise of results.

The reset button for any instrument display tallies ( fuel consumption, average, trip miles, etc ) is located on the sterring wheel. It should be the button on the lower right with the down and back arrow printed on it. Once you display the item you want to reset, hold this button for a few seconds and the display should reset to 0.

Good Luck
