Hello oldiro: My name is Roger and I can help. From under the vehicle look up between the transmission and the side of the block. Mid motor above the pan rail there is a bolted in sensor. This should be the crank sensor.It will have two wires plugged in to it. Please rate this answer as this lets us know you received the information you asked for. Should you need further help please just ask. Thank You for using FixYa. Roger

That drain line is for the box that holds the air conditioner evaporator and the heater coil. It seems that your heater coil has sprung a leak and the leaked fluid is coming out the drain. You have to replace the heater coil, which on most cars involves removing a lot of the interior equipment, including the dash board on many cars. A job best left for the repair shop unless you're very adventurous and patient. Even then you will have to take it to a shop to have the air conditioning system recharged.

Testimonial: "Marine like i said in my feedback your input was clear enough for me to make some decisions. Thank you. "
electical is hard to diagnose with out being there. i would treat each problem seperately. first you will need to test the engine temp gauge sending unit. in a dealership this is easy with a scanner they can run a sweep test to se if the gauges are responding.you don't want the engine to over heat if the gauge is not working. next problem the dome light should be easy to fixe does the dome light work with the dome switch?remove the bulb and with the doors open and switch on check for voltage, if voltage check connection and or replace bulb. if no voltage check fuses for voltage.last will need to have the dtc po243 checked out by a repair shop. i hope this will help.

I have a 2003 Pontiac grand prix...I've lost power, it won't go over 30mph, it doesn't shift thru the gears smoothly. The service engine soon light goes off and on, more so when I'm trying to gas it. Its seems as tho it's 'being choked'...like not getting gas or air. So far, I've flushed the ******, changed the plugs, wires, air filter, fuel filter. I suspect the problem is a clogged cat convertor. I've been told that the exhaust can be opened a little near the cat to allow air to flow in....that should confirm if the problem is the Cat or not. I'm testing that theory today.
