In cold weater hard starting need to cycle through intake heater

In all cars that I'm familiar with, closed loop doesn't apply during the start cycle "Motor Man". You need to look in other areas to determine why you're having a hard start - whatever criteria you're using to determine what a hard start is.

probably need to be using a lighter weight oil. I use 5w-30 in central Texas. If you are that far north, where oil gets cold and thickens up....

have dealer verify by dropping off for service, parking outside overnight, and then try to bring it into the service bay next morning for service.

first is the idle air control valve that controls your idling, the overdrive is a very common problem with ford transmissions .It is a easy and cheap. I get a lot in my garage. you need to replace shift solenoid c it is on the valve body in the transmission. this is my linkhttps://www.facebook.com/TedsRepairs

Have you checked your glow plugs? Sounds like one or more may be faulty.

I have a 2000 pontiac grand prix with a digital climate control system. The heat quit working, it doesn't blow out any heat. Now that it is warm outside the air stopped blowing out any air. The digital temperature on the climate control is not correct. When it states that it is below 30 degrees on the ext and it is warm outside the air wont be cold. Once it starts going above 30 degrees the air gets colder. Today the blower stop working all together. Was told it maybe the climate control unit was bad. You can hear the door opening/shutting when you switch the temp from cold to hot. But there was no heat blowing out whatsoever in the winter time. Could you please give me your opinion on whether or not it is the climate control unit or something else?

Have a block heater installation the day light things warm up at night it gets really dry cold that's when the block heater keeps the engine warm enough to start.

If plugs, wires, and battery is new and good, make sure you are using 5w30 oil which is thinner and is made for winter. If needed, replace the fuel filter. There is a cold start valve that may be giving you problems. You can go to autozone.com and register for full free online repair manual for your car.

this motor has two starting aides. one is the glow plugs under the valve covers. the other is an intake manifold heater.either one will cause hard starts. both can be chked with an ohm meter. be sure to disconect you neg battery terminals before attempting. there is some high voltage under the valve covers

I am thinking that there may be a fuel bleed down problem if this is an injected engine.

Try this, turn on the key, but do not try to start the engine for 30 seconds. Then see if the engine will start on the first try.

As for wearing the battery down, cold is hard on a battery, so having an engine that starts easy is easier on the battery.

The same problem happened to me and it turned out to be my heater core.

Normally smoke will come from the heater core when it needs to be replaced.

Also the smell is most likely anti-freeze and and you normally smell it when your
engine is running warm or hot.

Check your coolant levels to be sure. and the hoses leading to your Heater Core

heater cores for that vehicle normally run $180 - $230 and you need to remove your
entire Instrument Panel (IP) (Dashboard) to replace it.

I hope this helps!
