The engine not start when its cold , only with starting fluid , then when its hot , it can start , good

Check your power steering fluid level ?

To start, the first thing I would check is the fluid level in your cooling system. Do not remove the radiator cap if the engine is hot! The water will shoot out like a geyser and you could get burned or scalded by steaming hot water. Best to check it when the engine is cool.
If you need to add fluid it should minimally be a mixture of 50% water and 50% antifreeze. This way the fluid won't freeze in the winter or overheat in the summer.

Check the hose that runs from the radiator cap to the overflow container. Make sure it doesn't have any holes in it and it is not plugged up. Make sure the overflow tank has fluid in it to the level indicated on the tank.

These are basic, simple things to check. If these don't remedy the problem other possibilities are a bad thermostat, water pump, radiator cap, or a plugged heater core.

There are many possible causes for this. A good place to start would be to make sure your radiator fluid is filled up to the cold level when the engine is cold and to the hot level when your engine is hot.

Top up Fluid level in over flow tank and radiator ( when cold ). Run engine to normall operating temperature and check for heater blowing hot air.Good starting point.

HEY DO THIS,YOU NEED TO BLEED SYSTEM. TO BLEED POWER STEERING SYSTEM.TO DO THIS.FILL THE POWER STEERING RESERVOIR TO COLD FULL MARK ON DIP STICK.WAIT A FEW MINITES,FLUID LEVEL DROP ADD MORE FLUID UNTIL REACH COLD MARK ON THE DIP STICK..WAIT FEW MINUTES.START ENGINE LET IT RUN FOR 2 OR 3 SECONDS.TURN OFF ENGINE CHECK POWER STEERING FLUID ADD MORE FLUID.DO THIS UNTIL FLUID LEVEL STOP DROPPING.WHEN FLUID LEVEL STOP DROPPING.SAFELY RAISE FRONT OF THE VECHICLE UNTIL FRONT WHEELS DONT TOUCH THE GROUND.START ENGINE UP.TURN THE STEERING WHEEL GENTLY FROM STOP TO STOP,CHECK THE RESERVOIR FLUID LEVEL LOOKS GOOD TURN OFF ENGINE LOWER VECHICLE .LOWER VECHICLE TO GROUND. LET VECHICLE SET FOR 2 MINUTES CHECK POWER STEERING FLUID LEVEL.IF STILL LOW ADD LITTLE MORE.TO THE COLD FULL MARK ON DIP STICK. DONT OVER FILL BECAUSE FLUID LEVEL RISES WHEN IT GET HOT.WHEN DONE IF STEERING WHEEL STILL FEEL HARD TO TURN YOU SEE AIR BUBBLES IN FLUID THATS WHEN FLUID HAS A TAN LOOKING COLOR WAIT 5 MINUTES AND.REPEAT THE BLEEDING PROCESS. DONT DRIVE OR OPERATE VECHICLE ON HIGHWAY UNTIL POWER STEERING HAS NORMAL OPERATION.

Hi,
I would recommend disconnecting your glow plug relay if you are going to use starting fluid.
With starting fluid in the engine and the glow plugs turn on it may explode the fluid and do head damage. Starting fluid and any kind of ignition source ( hot glow plug ) is like a bomb.

You need 3 things.
Compression
Good hot blue spark to all plugs.
Good gasoline and proper fuel pressure. 63-64 lbs.
If you have all 3 then move on to injector pulse to all injectors.
I think each injector is on a separate driver on that one.
Check for pulse to all of them.

You may be weak on fuel pressure . Even a couple of lbs low on a cold start will cause a no start. Double check cold start cranking fuel pressure. If under 63-62 lbs you have problems.one test is to give it a squirt of carb cleaner not starting fluid. If you get a intake or engine full of starting fluid it can blow things. Carb cleaner will start it if it is a fuel problem and lot safer. Also in the good old days when i was a kid, i used to get a couple of cans of starting fluid and get in the back and have a good starting fluid spraying contest. Good for a big blast if someone lights a match. If it starts then you have a fuel pressure problem. Run the full fuel pressure test and post back pressures.

Here is the guide lines on testing.
Hard to start cold.
Check cold start fuel pressure.
Check engine running fuel pressure.
Check engine running on the road fuel pressure.
Then shut it off and watch for fast leak down.
Pinch off at rubber part or block off return line and check full pressure.
V8 gm engines should have 60-66 fuel pressure.
Cold start should be 64-65 lbs of pressure.
If you do not have full fuel pressure on a cold start the injectors will not squirt fuel. Do not leave home without it.
Engine running should be 60-66 lbs pressure depending on engine load.
Full pressure with return pinched off should be 75-85 or more.
And if it has a fast leak down after shut off you have a leak.

The 75-85 is only a check on the capable full pressure of fuel pump.
If you can not find the rubber return line check full pressure by plugging return line or just or the true full pressure can be taken direct at the end fuel filter.
What are the pressure readings that you have done.
What are your cold start pressure readings?

It should not be a matter of how hot, but when. If it only happens when the car is hot then I would check the level. While checking the level, I would see if there is any blackish stuff in the fluid. If there is then I would have your tranny rebuilt because the clutch material is breaking down and could be the cause of the slipage.

Change transmission fluid you may have a clogged/sticky valve body in transmission and that will restrict flow of fluid and pressure when cold. Check Fluid level before.. check wen vehicle is hot and running on flat surface. Good Luck and thanks for using FIX YA

first of all the engine must be running when you check your automatic transmission. when the engine and trans is cold (you just started it for the first time of the day) the fluid should be up to the cold line when the the engine is hot(you have been driveing for awile) it should be up to the hot line.
