A bit of a vague question but if it's overheated, I'd suggest a new head gasket and skimming the head

Hi,the heating is also controled by the firmastate which could be the falt,it contols the engine tempriture when you have the heating on the fermastate will close a bit so that when the heat is drown away for your heating the engine stays at its optimal running tempriture,so if the fermastate is stuck open when the car is in motion it will also have the radiater cooling the car down so the heating will get cooler,but when the car is at a stand still the heating will work as the car is not getting eney cooling from the radiater,there are tests to check the ferastate but if you take it out you might as well replace it. Hope this was some help.

rbbnsent: Let me see if I can help you.Fird, your vacuum lines are color coded if you look closely. As they age, some of them get difficult to differentiate from. One place where you can positively ID them, is where the line has not been exposed to the elements. That is where they have been inside a vacuum hose.
Starting off, the vacuum line which shuts off the engine is a brown/blue line it goes to a diaphragm that has the fitting facing parallel to the pump body (runs parallel to the ground) Hook the line into the diaphragm.
Next, you have a vacuum hose which has a check valve on it.
Connect this one to the fitting which runs straight up.
There should be a white line near by. Hook the line up to the fitting just behind the one you just hooked up.
There should be a Black line going into the back of the pump.
Alright, coming off the vacuum pump, you have a fitting which should 4 lines excluding the vacuum source.
Now the vacuum source should have a check valve in line with it.
The following colors should be going into this "T"
White, white/blue, green, white/black.
Going back to the injection pump: Coming off the line which had the check valve, one direction is white/violet/brown and the other direction which heads off in the same direction as the front of the motor, is black.
The Black line coming out of the back of the pump hits a "T" which goes to a check valve and it hits another "T"
Coming off the side of that "T" is a white/green
I'm pretty sure, I have far exceeded the number of vacuum hoses which you found disconnected.
I hope I have answered you question thoroughly.

engine could have faulty clutch fan causing engine overheat or fuel pump going bad,soon as car stall out check fuel pressure with engine off.if you have 80 to 90 psi with new fuel filter fuel pump okay.if you have zero fuel pressure fuel pump not pumping any fuel.

when the car ignition is turn on all accessory lights should lite up telling the computer everything is in good contact. If none of the dash lights is not lighting up you don't have a good ignition contact and computer is not getting any power. your stater will crank and turn the engine over only but the fuel pump and ignition module and other accessary is not turn on, the car will not start. What turn everything on is your computer, computer; control all items like fuel pump, sparks etc. You have to get all dash light working again in order for computer to turn on. Check all the fuses and relay under the hood, next your ignition switch in your steering wheel may be faulty allowing only starter to work and not others. this unit wear out and common problems to all cars, parts is 35 buck to replace and you going to have to take the steering columns apart to get to it. Not easy but it will take time. Get all the dash light working and you will be back in the game. good luck and hope that help some

first check signal lights fuses if none of signal lights work.if fuse okay,check for burn out bulbs.if all is good turn signal switch is bad or you have loose wire to signal switch if your turn signal lights work some times.
