    1997 Dodge Grand Caravan 3.3 engine M.P.F.I. Will not start when it's cold unless I remove airbox and spray starting fluid into intake,then replace airbox.Then it will start after a few min. Could it be "COLD START VALVE" ON FUEL INJECTOR?

    we replaced the ecm last year for the same thing helped untill it got cold again . If you wait for a little bit with the key in on position you can here a relay start to chatter  when it guits chattering it will start but it acts like it is flooded.

    Can you confirm year, make & model, engine, and tell me any other time it does it, perhaps after sitting a certain amount of time, or anything else? Also, have you tried cycling the key to "ON" only, (not start) a couple or 3 times first before you try to start it?

I'd be real tempted to replace coolant temperature sensor, as it sends signal to ECM regarding engine temperature and fuel requirements pertaining to that temperature. For example, it tells ECM that engine is cold, send more fuel for cold start, but if it's defective, doesn't tell ECM to do so, or gives ECM the signal that engine is already warm, and doesn't require that extra fuel now for start up.

I have a 1997 Chevy cavalier that doesn't start when the weather is cold it will not start early in the morning but will in the afternoon

If it runs normally except for that problem, I would suspect the coolant temperature sensor. The sensor may not be reporting the coolant temperature properly when it is very cold and then the ECM will not provide enough fuel to start the engine (basically you have no choke). Once it warms up a bit, then it starts ok and runs well.

Rear hatch will not stay open when weather is cold, temps below 45 affect the vacuum on the rear hatch. works fine in warm weather

Those little shocks are gas charged, thus pressure increases in hot, and decreases in cold. Over the years they tend to seep, or leak a bit, thus, only work good in warm/hot weather. They have replacement ones at autoparts stores, and shouldn't be too expensive.

It cranks, but it does not run

Have you check the plugs, cables, cap/rotor ?

One thing you can try since it starts good in warm weather, is to ,on a cold morning, take a hair dryer and warm up the suspect part to warm weather condition. Then try and start the car. If it start ok you have probably found the weak part.

Fuel pump not running only in cold weather

Pumping the pedal on an injected engine does nothing, except varying the air intake amount. I would change the fuel filter (if badly plugged, it may be causing the pump to shut off early) and clean the idle air control valve.(which should regulate idle air flow, eliminating the need for playing with the pedal) The valve itself is not difficult to service, but is a bit delicate. It can be cleaned with carb cleaner. just make sure you do not turn the valve end around while cleaning, and re-install it perfectly straight. You may have a bad drain back valve in the pump, but this is less common than what I outlined above.(there are tests for this)

This sounds like a weak battery. The lights, horn, etc., are all very small loads. The starter is the hardest item for your battery to push. You can take the battery to an auto parts store and they can perform a "load check". If it shows weak, then let them put the battery in for you. The reason it is harder to start in the morning is, it is the longest time since the battery has been charged, and it is usually cooler in the morning. Batteries hate the cold.
