SOURCE: 1999 toyota tacoma Sr5 won't start

Check for fuel pressure when starting. Fuel pumps have a check valve in them that keep fuel in the rail at the injectors. If the check valve fails, the pump has to pump fuel all of the way up to the engine. Same thing with hot no-restarts. Fuel pump.

Might want to look for vacuum leaks. Most misfires that go away with gas are caused by manifold vacuum leaks. The cat code can also be caused by the vac leak. There are different methods to find them and not real easy-but one way is to get a can of carb cleaner spray and spritz around intake areas. When the carb cleaner finds the leak--the car will run good for just and instant. Could be a rubber line or a manifold gasket. Hope it helped. Thanks

Symptoms will not accellerate

If you have a manual gear box check that the clutch is engaging properly (cable operations jam in the case and hold the clutch off---hydraulics will hold off from a blocked compensating port in the master cylinder). If auto transmission have the fault codes read and look for TCM and/or torque converter clutch solenoid fault. check the oil level in the transmission and if not bright cherry red have it replaced . have a pressure test done to determine any internal faults.

6cyl,1994 toyota camry shuts off when shifted, but when car stays on it doesn't go with full power and over heats an shuts off. takes a couple of startups to get to stay one when its cold it shift

your catalytic converter may be clogged, if it is bolted on loosen the bolts and pry it away then try to start. if the power returns then you need to replace the catalytic converter. also is it an automatic or standard transmission? If automatic the torque converter is stalling at to low of rpm and needs to be replaced.

What is the solution when car cannot accelerate when engage in drive

Automatic or manual trans?
If the engine does not accelerate and just basically stays at a fixed RPM when you push on the gas then it sounds like your catalytic converter is clogged and choking the engine. I had this exact problem on a Isuzu impulse. If the engine races but the car doesn't go anywhere then it's your transmission.
