Question about 2004 Chevrolet Suburban

1 Answer

Will not start when cold

Ocasionally, the surburban will not start when cold. Once started it starts fine the rest of the day. Starter spins engine it seems faster than usual. Could this be a module in the electronic spark system? I had this happen once in another chevy vehicle. The starter would spin the engine faster than normally required to start it. Currently it will not fire at all.

    You will have to verify first if it is a igniton problem ( no spark ) or a fuel problem ( no fuel to the Injectors.) or both. Then isolate the problem from there. Good posibility that the fuel pump is starting to go. Check all this when first starting the vehicle cold. You may need a helper & a fuel pump tester.

I have a mechanic on stand-by to replace the fuel pump. He told me I might be able to get the suburban started by using a rubber hammer on the fuel tank while another person engages the starter. He said sometimes this might break loose the brushes and start the fuel pump going again. I thought this would be worth a try and wanted to let other folks know about this temporary method of getting the car going again. Might save a wrecker bill. Thanks.

When I turn the key the stater spins, but i does not turn the engine over.

Maybe problem with starter motor? It does two things, it kicks out the starter drive gear and spins. The flywheel usually has cover, remove the cover, try to see if starter drive gear engages the flywheel teeth, with key in the crank position.
Some of the national brand auto stores will test the starter for you. Sometimes, I take the starter off, lay it on the ground, hook up jumper cables properly from battery to starter motor. It should kick out the drive gear and spin, granted that is no load test. Intermittent issues can be a pain.
I just want to add, when working under a vehicle, safety is always your responsibility.

I just wanted to add, make sure battery has a full charge and battery connections all good.

My car doesnt want to start up right away in the morning. Almost like its really cold out and it takes it a min. The rest of the day its fine runs great. Any ideas?

Reason 1 - Gasoline, like any other liquid, evaporates less when it is cold.You have seen this -- if you pour water onto a hot sidewalk it will evaporate a lot faster than it will from a cooler place like a shady sidewalk. When it gets really cold, gasoline evaporates slowly so it is harder to burn it (the gasoline must be vaporized to burn). Sometimes you will see people spray ether into their engines in cold weather to help them start -- ether evaporates better than gasoline in cold weather.

Reason 2 - Oil gets a lot thicker in cold weather. You probably know that cold pancake syrup or honey from the refrigator is a lot thicker than hot syrup or honey. Oil does the same thing. So when you try to start a cold engine, the engine has to push around the cold, gooey oil and that makes it harder for the engine to spin. In really cold places people must use synthetic motor oils because these oils stay liquid in cold temperatures.

Re ason 3 - Batteries have problems in cold weather, too. A battery is a can full of chemicals that produce electrons The chemical reactions inside of batteries take place more slowly when the battery is cold, so the battery produces fewer electrons. The starter motor therefore has less energy to work with when it tries to start the engine, and this causes the engine to crank slowly.

All three of these problems can make it impossible to start an engine in really cold weather. People either keep their cars in heated garages or use "block heaters" to get around these problems. A block heater is a little electric heater that you plug into the wall to keep the engine warm.
i hope it was convince answers

My 1994 ford mustang gt is hard to start in the morning and even harder to start if it sets for a couple of days, and doest seem to go to a faster idel when it's cold; but once started runs and idels...

This is due to the fact that it possibly hasn't gone for a check-up in quite a long time. There are only two things that can cause this kind of problem and they are
1. If the battery is low or the kick starter is bad. A very good way to determine if the battery or kick stater is good is to watch out for the sound that the engine produces while you keep trying to start the vehicle. If you notice any kind of slow winding of the engine gears(i.e sluggish sound instead of usual energetic sound). A bad kick starter would lead you to keep trying to start the engine and eventually make the battery to die.
secondly, there might be a problem to your fuel supply. It might not be supplying enough fuel into the combustion chamber (be it carburetor or injector) therefore limiting the supply of available fuel to start up the engine.
The best thing to do is to send it to a mechanic to run a complete diagnosis on the engine to know if there might be any other issues as this is a very old engine and requires delicate care.
Hope this solution was helpful to you? Please comment for more information

How old is your Battery? at the Temp. Stated above an Older Battery even though Good may not have Enough Cold Cranking Amps Left to Kick her Over.
