It can be any of a number of problems. Possiblities are: Oxygen sensor, air filter, fuel filter, plugs, wires, rotor, distributor cap, throttle position sensor, MAP sensor, carburater, compression... and who knows what else without knowing more of the symptoms. If the vehicle is injected, it probably has a computer diagnostic port. If that's the case, borrow, rent or buy a code scanner and use it to find out exactly what the computer has detected. egr valve i just went through the same issue
It can be a myriad of things. Drive the car to a trusted mechanic and have them scan the ECU with an OBD2 scan tool. The tool will retrieve the code that has been set. This code will tell you what parts are being effected and a possible repair.
Barricades Of Heaven
Depends if they are pushing it up hill or down hill, or on flat ground, or off a ledge/ cliff Is the rock round or cube shaped? Assuming the rock is roughly round, and it is up hill and the people pushing it are Disney characters the forces are Gravity,, friction, Sleepy, grumpy, doc, bashful, micky minnie and goofy.
if it starts i might need the carburetor tuned or cleaned or check the spark plug gap
You need a battery. There's a very small chance it could be something else, but from the symptoms you describe it is more than likely a bad battery.
check your camshaft sencor and your crankshaft sencor.
I have to guess at a few things but.. I am guessing because the engine has serious problem with how it is running the engine computer has increased the idle speed very high to try and keep it running. If this is the case putting it into gear will bang very hard and drop the engine speed to below what the engine control computer can keep it running. So it quits. Get the engine fixed.
Lack of fuel or too much fuel will make the engine stop running. Since you are able to re-start and run for a short while, the problem is probably a clogged fuel filter. You might also want to check the air filter.
If this is a general noise, it could be the transaxle. When you are accelerating, the engine is pushing the gears, and when you let go of the pedal, the vehicle starts to shift back down. If this is an engine noise, it could be predetonation or a valve problem.
Be sure the cooling fans are functioning when the ac is running.
Many engines have an automatic shut off when the engine becomes too hot. Once the engine cools down it may also be equipped with an automatic startup.
When the engine 4jg2 starts then its stops it is due to a mechanical failure.
Fuel pump
Carb.? May need to be re-built or replaced
You may have a faulty engine light. Or, you may have a serious problem with your car. You should take your car to a local mechanic for diagnostics.
The timing on your truck is probley off mine had the similar problem. If you don't have i timing light, you can always do it by ear. Just turn it clockwise till your engine starts up if it starts up your close, if it stays running turn it little buy little till it purrs..
Need to check fuel pressure and fuel filter first. I think you will find your problem there.
