Why is my 94 toyota camry sputtering and shaking when i start it and it wont run?

When I start my Toyota Camry it shakes and sputters and is very noisy. Then when I put it in gear it shuts off.|||A defective sprag clutch in the converter will not allow the vehicle to go into low or reverse. Assuming the transmission is full of clean fluid, if going into gear is very slow, or not at all, a good place to begin looking for a problem is the converter. Remove the converter by removing the transmission. Inside the converter are engagement tabs and a spline. Using a couple of long screwdrivers, wedge the spline so it will hold. Try and turn the tab with the other screwdriver. It should free spin in one direction and hold firmly in the other. If it doesn't, the converter is faulty.





Another good place to look is the pump pressure if the transmission will not move at all. Although this is rare, since most pumps are very reliable, a quick check is to loosen a transmission cooling line and start the engine. Most cooling lines are at the radiator. While this is not an exacting test since a pressure gauge should be installed, a sound pump will spray fluid under a fairly high pressure. (Wrap a rag around the fitting to prevent the fluid from going everywhere). If you don't see a gusher of fluid, you have a pump problem. Only run the engine a few seconds to prevent running the transmission dry. Before you condemn the pump though, check the transmission filter. This requires removing the service pan, but it's worth the effort. A plugged or dirty filter can cause low pressure problems.


Torque converters contain a one-way clutch. If the clutch jams and locks the stator (which normally keeps the stator tuning only one way), the converter cannot circulate the fluid properly between the impeller and turbine. The resulting turbulence inside the unit can cause a lack of power at highway speeds and may cause the engine to overheat during cruise conditions. A locked one-way clutch will also cause the fluid to run dangerously hot, which can damage the transmission and lead to transmission failure. If the one-way clutch fails to hold its position and freewheels in both directions, the torque converter cannot multiply torque normally and the vehicle will accelerate slowly (like starting out in 2nd gear). The only cure for either condition is to replace the torque converter.


Torque converter shudder fells like a slight to heavy vibration in the transmission, and is usually accompanied by an interruption in power transfer. It generally occurs at part throttle and light acceleration, between 15 and 50 miles per hour, just before the shift to one of the top gears where the converter reaches "lock-up."


Transmissions can shudder in a very similar manner to torque converters. To determine whether the shudder is tranny or TC related, run your vehicle for a little while till it begin to shudder and immediately park it. With your foot on the brake, put the transmission in Drive, and apply light throttle. If you feel shuddering, then it's the Torque converter; if not, then the problem is within the transmission.


Unless there is physical damage to the converter or transmission, shudder is a fairly easy problem to solve. Once the transmission fluid has been overheated enough times, it becomes permanently de-polymerized and need to be replaced. You can do this yourself by draining the transmission and flushing it, or taking it to any competent mechanic for maintenance.|||First check to see if your getting enough fuel to the injectors,check the fuel pump to see if its working.Most of the time you can pull up the back seat bench and get to the pump.Once you do that turn the key to the on postion and listen for the pump it will humm.If that checks out check your spark plugs and wires one maay be fouled out.
