If steam is blowing out when the heat is on, the heater core is leaking into the car. If water drenches the floor after running a lot on a humid day, the condensate drain tube is plugged. It is a rubber tube flattened on one end connected to the air box half mounted on the firewall under the hood. Check the coolant level in the radiator to make sure it is at the correct level. If it's not, then suspect a leaking heater core.

Check the signal from the Vehicle Speed Sensor with a scan tool, that is the most likely cause.

Why it called DexKILL Your best bet take it to a qualified repair shop ! Once the thermostat kicks in the temp lowers which is great. I know we have to replace the thermostat The thermostat doesn't kick in , it opens !!!! And if the temp. goes down when the thermostat opens ,it's working ! The redish clay looking stuff is rust , air got into the system . You probably have a bad radiator cap . Now you need a compleat cooling system flush ! Your heater core is plugged .

Did you use a Delco rebuilt Alternator? The ones you get from so called discount auto parts stores are junk and they may be the cause of this problem, monitor the output of the system with a DVOM meter, does the voltage fluctuate? Have you check all the chassis grounds? They are the biggest source of this type of issue when the Alt. is ruled out.

the voltage from the big red wire is battery power the smaller wire will not have voltage until the alternator is running one wire goes to the charge light to the voltage regulator check that the voltage regulator is operational better still get an accredited auto electrician to check the charge circuit , voltage regulator and alternator for operation

remove everything off the front of the engine.

check for a broken engine support, had someone push gas pedal and holding brake in reverse, if engine jack by itself engine support is broken and pull on broken hose of mass air flow (air filter hose)

drivers side below air filter housing

Ok you have power at the battery, do you have power to the plugs. Given the limited information provided about the no start. Start from the basics. Fire, Fuel and air, with fire and fuel being essential for a start. Fuel is sent to the combustion system, air is introduced to atomized the fuel, the spark-plug fires and the atomized mixtures explodes to initiate the starting process.

is switch good? try checkin wires for continuity with a meter

You do not say if it is an automatic or manual transmission (clutch). I will assume auto. This could be several things. It may be something as simple as low fluid or possibly the transmission filter needs to be changed and the old fluid flushed out. Or the transmission could be starting to go bad and would need to be rebuilt or replaced.

SHOULD BE SEPERATE FOSE

take out the inst panel and remove the wires and put them back in four or five times, could be a bad connection

Will your Center High-Mount Stop Light (CHMSL) illuminate when you depress the brake pedal, but the lower/outer lights will not?
-- Do you have to hold the signal lever in a certain spot to get the turn signals to flash?
-- Do you have to hold the signal lever in a certain spot to get the lower/outer brake lights to illuminate?
-- Will the signals work in one direction, but not the other?
If you answered yes to any of the preceeding questions, your turn signal switch is likely malfunctioning.

**One more question before we continue: Is the turn signal lever not "cancelling" (returning to the "off" position) after you make a turn? If this is the case, you have a broken "cancelling spring."


Before you begin disassembly of your steering column, verify the turn signal flasher is not malfunctioning. If your brake lights work fine, but not the signals (either direction,) then it's likely the flasher is burnt out. The flasher itself is located underneath the dash near where the steering column passes through the firewall
