More than likely the fuel pressure check valve is defective.

Tip

Vehicle won't start when hot


A common problem that's surfaced a great deal lately is a car/truck that starts fine when the engine is cold but won't when the engine is warm. Most of the time, the car will require a jump start with a warm engine to get it to start. Most mistakenly assume a bad battery and change it out, only to have the same problem. What happens is most starters don't just "quit" when they are defective. A bad starter will usually start your vehicle when it's absolutely cold. Once warm, the starter will behave as follows:<br /> <ul> <li>No power</li> <li>Click then nothing</li> <li>All other electrical is fine (headlights, stereo, alarm etc)</li></ul> If your car or truck won't start when the engine is warm, but starts fine when it's cold, you most likely have a bad starter. Although replacing the battery is less expensive, it rarely (if ever) will resolve this issue. Consider the age of the car / starter when these symptoms occur. If you have an older vehicle (older than 5 years) then replacing the starter is a good place to start prior to buying other electrical components (battery, alternator). <br /> <br /> Always bring the vehicle to a shop that offers a free electrical diagnostic test to confirm the electrical system is sound to rule out an electrical problem first. If the electrical system is sound, I'd go ahead and replace the starter. <br />Although this tip will show under the Lincoln category, it applies to all makes and models.<br />

I have a 2004 Trailblazer and my rear a/c starts out blowing cold air but gets warm shortly after but the front a/c keeps blowing cold air all the time???? what could cause that ????


Just a little low on freon can make it get too cold and it freezs if you in position to check the freon level you'll find with the system on high and the engine reved up the low pressure is below 25PSI. fill it to reved up is above 25 and your problem will go away. Low on freon will make it cold enough to frezze up and then warm up as the air does'nt go though the ice. it'll work good as you start up till it frezzes and after it's stopped up with ice it blows warm (it's really too cold). the more freon in the system the warmer it'll all blow because all the pressures are higher and it's the difference in pressures that make it cold.

My accord sometimes doesn't start. mostly does it when its hot outside. what causes this


How old is the battery? The extreme heat of summer and the extreme cold in winter take a toll on batteries often causing intermittant starting problems if the battery is four years old or more, or if it is a cheapo battery that is a few years old that is probably the problem.

My 2004 BMW 745 has been sitting in my carport after I had an in home accident,The battery is dead.I got an electrical charger but do not know how to re charge.Some say undr the hood.Others say trhrough...


The jumper cable connection point under the hood is directly connected to the battery. If you are not familiar with charging batteries, it is much better that you connect your charger under the hood.
Leave the ignition turned off. Connect the positive (red) clamp to the jumper cable connector under the hood. Connect the negative (black) clamp to a bare metal ground point such as a bolt or lifting lug on the engine. Then plug in and turn on the charger. Let it charge for several hours before trying to start the car.
If this is the original battery, it likely won't ever really work well again. Maintenance free batteries do not respond well to being completely discharged, and at 7+ years of age, it is due for replacement anyway. I had to replace the battery in my wife's 2004 BMW 330 about four months ago, and it had never been allowed to go dead,

2004 F350 6.0L starts rough and runs rough until warmed up. When it was newer I could start in cold weather and run smooth with full power right away. Now it has no power at all until warm and is hard to...


What tells me, is that the thermostat is staying open after
your done using the truck
When you start it up cold, it takes longer to warm up the area
near the coolant temp sensor,which is part of the system
to put the PCM (computer) into closed loop
Closed loop is when you leave a computer fuel stratagy and
the O2 Sensors take over fuel control

Hard to start----

Need spark plugs that have not been in the motor over 60,000 miles
Spray the throttle plate with CRC Throttle Cleaner
Spray the MAF Sensor with CRC MAF Cleaner
Need all ducting in place,no vacuum leaks and a clean air filter
Make sure your O2 Sensors are tight
A fuel filter not over 3 years old
Hope the coolant temp sensors works correctly

Anything more gets too technical

AC blows warm air when it rains


It sounds as if you have an ambient temperature sensor that is either shorting out when it gets wet or either the water is acting like an insulator and sends an incorrect reading to the body control module. You may want to contact BMW to the specific location on your particular year and model. As location will vary with model and year.

2001 530i battery drain/alternator question


first off never never never trust a tow truck driver they are idiots, it takes a BMW 15 mins to go into a sleep mode before a draw can be mesured, as for the dealership they should have caught that using the Midtronics batt/alt tester that is standard from BMW 2.5 years for a batt replacement is reasonable especially in a BMW based on the high demand on the electrical system, I just replaced an alt on an M54 enginge just today so they do go bad, have them give you a print out from the midtronics with your VIN on the printout showing your alt is bad and what the batt is.

Won't start


Most vehicles have problems starting when it is cold. Short of installing a block heater, your problem lies in your battery. if it is cold in your area for a few months of the year, my suggestion is to invest in a higher rated CCA battery, and a block heater.

Cold Cranking Amps is a rating used in the battery industry to define a battery's ability to start an engine in cold temperatures. The rating is the number of amps a new, fully charged battery can deliver at 0° Farenheit for 30 seconds, while maintaining a voltage of at least 7.2 volts, for a 12 volt battery. The higher the CCA rating, the greater the starting power of the battery.

This morning it was -19F here, and my new car gave me a fit starting, so you are not alone. Replace the battery, and pay a little higher premium for CCAs and you should be fine.
Good Luck.
