    ok thanks. water pump tho never know when its going to go out if that is the problem. Tensioner may be. I will be flushing out radiator soon and putting in new thermostat ,, might help the pump if that is the case. A dealer did a test and claimed the power steering needed a flush out too. Any thought s on that ?

Recently developed a whinning when I first start to move


Where is the whining noise actually coming from .. engine/gearbox or elsewhere?
A whining/screeching noise could be a drive belt .. such as the belt that drives the alternator.

On a manual car it could be the clutch bearing making the noise until it warms up. Does the clutch make a noise when you depress the pedal? That's the thrust bearing .. the bearing that operates the clutch.

I don't think you have too much to worry about. If you had engine trouble there would be knocks, rumbles and strange noises at all speeds.

A whining noise is usually associated with something spinning/turning .. such as a pulley/idler on a drive belt or a bearing alternator.

Put your mind at rest - get a mobile mechanic's opinion.

2002 Chev Blazer 4wd with 4.3. Cold or warm the engine cranks for several seconds before it fires. Then it runs but is flooded and takes a while to clear.


it sounds like you may have a pressure problem , not a flooding issue , this is a fuel injected motor and is probably losing fuel pressure , this could be at the gas tank , fill cap , fuel filter, to the injector rail , many places to check , I would have this checked by a pro as this is a fuel issue "BOOM"

Truck fails to start


The 01 DuraMax trucks do not have a block heater, unless they were special ordered with one. Just turn the key to the on position a few times before you try to crank it, and hold the accelerator partially down while doing it. However, don't hold the accelerator if it starts to crank, it DOES need a minute to warm up before being revved. Also, use a diesel treatment when its cold, it helps a lot.

1. Have the refridgerant fluid level checked. (Could be low)

2. Have you tried putting it on recirculate? Could be a venting issue.

Other than that it's out of my league.
