Question about 2003 Chevrolet Suburban 1500
2003 Suburban starting problem
My Suburban starts always on the second crank. Sometimes I move the key forward and hold it for 2 or 3 seconds and then it starts. Does anybody know how to fix this? I have already had the spark plugs changed and that didn't help and I tried some fuel cleaners.

This may sound funny but unwind the cable to the ground lie on your back and kick the spare tire until you free it.

SOURCE: 2003 suburban idles to low.
the idle speed is computer controlled and not adjustable, slow idle is caused by a dirty intake, do the following.
Here are some of the causes of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Worn side bearings is where the noise is coming from and might as well do both sides, I used replace them in about 2-4 hours, depending on where Murphy happened to be. Disconnect both side inner CV joint, front prop shaft and the 4X4 actuator line. If you want to drop the front pumpken. Not sure if you have enough room if you want to change the bearing without removing the pumpken from the frame. You should see when you disconnect the CV shaft.
The front diffs are toys compared to the rear, if you use auto4wd too much there are bearings in your tranfer case that are similar to the side bearings in the front diff. In both appearance and durability and soon you'll replace those too.
Good luck and keep me posted.
