if you take to a AC repair shop they will do all the checks you need and if required top up the refrigerant , not at all costly and they have the correct equipment for the job , not really a thing for the home mechanic

A/C recharge

If you need to add refrigerant, you have a leak that needs to be repaired

You need special equipment & A/C knowledge to work on any air conditioning system

If you try & add you may hurt yourself & overcharge & ruin the
cars system as well

Have a trained mechanic do that kind of job

I have a 2004 dodge ram 5.7 liter . O have difficulty starting my truck. Some times it starts fine but other rimes I have to pump the gas and wen it starts a small amount of smoke comes out.truck runs...

I have seen two different problems with symptoms like this. 1. A leaking injector. If one of the injectors is leaking a small amount through the pintle on the end of the injector it will bleed the fuel system presure off and dribble fuel into the cylinder, fouling that cylinder. When you try to start it the fuel that has pooled into the manifold will create smoke when it does start. And since the fuel pressure has bleed off to zero PSI in the fuel supply lines it will need time for the fuel pump to recover the system up to normal operating presure. Presure testing (bench test) of the injectors is needed to verify this. 2. A bad fuel pump, relief valve, or bleed-back check valve will bleed the fuel system presure off while it is sitting. To find out if this may be the problem a fuel presure guage set needs to be installed and then run the engine, verify the operating presure is normal, and then shut the engine down and watch the fuel pressure for exessive drop.

The leaking injector is more apt to create the smoke when it fires up, but both can cause this. I would start with check #2 first. Of course there are many other things that can cause symtoms like this but these 2 are the most likely causes.

Hope this helps, if you have any further questions just ask!

A/c refill

Do you know if you are you connecting to the low pressure or high pressure lines, and are you really sure you need freon (which in this case is probably R-134A refrigerant and not really freon R-12)? It would probably be in your best interest to take your car to a reputable shop and have them fix your system. BTW, it never hurts to get several diagnoses and estimates.

Ac compressor would not come on so I jumpered the plug to the low presure switch and it came on so I tryed to add refrigerant to close the switch while the compressor was runing I added the refrigerant and...

the refrigerant that you add may not build up the required pressure to close the switch. sincd you noticed already that the system would not hold the charrge then you have a big leak.

you need to find that leak first, repoair it then charge it.

if you know how to do it then you will save a lot of money but it need a professional to do it plus the extra special tools that you require in order to do that.

you could trace all your outside lines for oil stains in the hoses, compressor, condenser, drier, fittings. if you can not see any sign of leak, then it could be in the evaporator coil which is covered by a plastic housing near the blower compartment.
that you can not see if there is leak so you have to bring it down. if you have a big book for your car, there could be a step by step preocedure on how to bring it down. follow it carefully and observe where the screws and bolts came from in order not to interchange them.

if you notice an oil spot or a rainbow once you immerse the evaporator in wter, then the leak is in the evaporator.

i hope i was able to FIX your problem
