    it was very cold, below 20 degrees, started the car let it warm up, backed out of the drive way, gave it gas, something popped, then its like it just wouldn't go. Thats when the popping began

Go to an auto parts store and borrow their OBD reader. Scan your Jeep for trouble codes then look them up or post them here - I'll be happy to help.

It could be a bad coil pack (not common), fouled plug (common), throttle position sensor (common)... any number of things.

SOURCE: car will not start

If this is a six cylinder, there were problems with the fuel pressure regulator leaking gas into the vacuum line creating a flooded condition. You might want to check map sensor,crank sensor.

SOURCE: what would make your jeep squeal is it a belt or

My jeep dosen't squeal...your does. The answer to your question is yes.
A loose or glazed belt can be noisy, a bad pulley bearing in anything the belt turns can also cause noise. If tightening the belt does not help, check each pulley with belt removed, for roughness, looseness or any binding.

Make sure that the timing is correct and that the spark from the coil is healthy. Problem can also be with the overdrive in the converter. If it's stuck on it can do that too.

I have a 2006 jeep grand cherokee larado. my rear lights shades are broken, where do i get it online?

I use these people> for my business all the time and have never had a problem. Just hit the big red start button find your car and I believe the section you are looking for will say body/exterior. You will need to replace the whole assembly as that is the only way they come. Even at the dealer. I don't work for them just use them. Good place for just about anything for your jeep. Hope this helps.

pumping the gas pedal does nothing but open a butterfly to give air to the engine, possible that the pump you got is bad or the fuel pressure regulator is bad , its part of the assembly

Grinding or poping sounds when making slow tight corners

Could be ball joints are bad. But if its a 4x4 the cv joint half (axle shaft) is bad.

Where is the gas leaking from? To clear a flooded engine, keep your foot all the way down on the gas pedal while you try to start the car. As it starts keep holding until it sounds like it's smothing out then slowly release. You can also change the spark plugs if that does not work.
