What kind of engin oil does a 2003 chevy suburban take? Its a 1500, 5.3 litre engine


the factory calls for 5W20W, this saves fuel and the engine is designed to run longer on the thin weight oil, never use any oil thicker than 10W30W, even in a very hot climate or u will damage the rod and the main bearings

Trying to find the fuel pump FUSE.


There is no fuse specifically dedicated to the fuel pump on this year and model of Suburban. This Suburban is equipped with dual tanks and as such has two relay switches, primary and secondary, both of which are located at the main fuse box in the engine bay, that power up the respective fuel pumps.

The closest fuse (15A) controlling either of these relays also powers up the main control module (located beside and below the main fuse box). So, if one needs to disconnect the fuel pumps from functioning, then the only effective method is to disconnect the fuel pump relays.

Chevrolet 2500 Not Running, May Be Fuel Filter Sensor


That red wire is only for the fuel heater.will not cause a no start.try pumping the primer pump on top of the fuel flter hsg. but first open the bleed screw,which is black plastic also located on the top.this will eliminate any trapped air that might have entered the fuel intake system.if the pump does not get firmer and harder to push, then you have a leak in the fuel supply lines or the ck valves in the fuel filter hsg or stuck open. Still no start have it scanned to ck fuel pressure while cranking.it should be close to 5000 lbs
