Hi Ken, Is the vehicle cranking (the engine turning when the starter is engaged or does nothing at all happen. If its the latter, I believe you have a problem with the battery. Get a friend to help with an jump start (Positive to positive and negative to negative) and then crank and it should start. If the engine turns but fails to start, when the ignition is turned on, do you see the engine check light with all the other warning lights. If not open the hood and replace the ECU fuse nod then try again. If you see the light, let us know and we can go on from there. Regards John

Good at start up then lack power under load,a plugged exhaust can do that.If there was a misfire that has been ignored the catalytic can only handle for so long. The 1994 Previa uses a vane airflow meter.so a torn intake duct can also cause lack of power under load,so check the air duct at the MAF to the intake and inspect for false air.

you may have a vacuum leak or the idle control valve is going bad

look closely at the valve cover there should be a cap that seas oil.

up to 1994 Previa's the cam sensors are located in the distributor, there is one for each cam. labeled G1 & G2 which are the center 2 of the 4 wires to the distributor, if you want to test them first. Also, top wire is crank sensor, bottom is ground.I believe you will have to replace the whole distributor.

the oil is filled and checked by lifting passenger seat and hatch. The under bonnet reservoir tops up oil as required to ensure all the oil ways are filled. This ensures the top end of the engine does not run dry. If all is well then you will rarely ever top this up. Try and determine where the oil leak is coming from and keep an eye on the oil level in the sump (under passenger chair)

Check if the fan is running. You may also have blockage in the radiator or coolant is not circulating properly. I suggest first draining the radiator and inspecting if there are debris in the liquid that comes out.

I would suggest getting the areas between the cylinder head and the exhaust manifold checked for leaks. Your description sounds like a classic beginnings of an exhaust manifold gasket leak.

Hi!

You night have a bad head gasket leak wish pushes the water up.

you must look under the motor you will find a oil pan it looks small at one end then curves
down to a bigger part thats ware you will find the plug it looks like a nut in the middle or
at one end on the big part

im going to find a pic for you

What water bottle? If it is the windshield washer, then either the hose, pump, or bottle itself is cracked. Find out exactly where the water is coming out.

If some other bottle, answer the first question.

Thanks, Jim
