94 chrysler town and country stalls after getting to a normal temp but wont start back up till its cooled down.


The crank position sensor could be bad.Check the injectors & fuel pressure regulator with this test.Hold the gas pedal to the floor while you crank the engine.Does it start??If yes,the fuel pressure regulator is bad or you've got a internally leaking fuel injector.Let the engine idle,pull the vacuum hose off the regulator and see if gas is inside the hose or gas is seeping from the regulator vacuum port.If yes,the regulator is bad.You can shut the engine off,wait 5 minutes then pull all of the spark plugs.If a plug is wet with fuel,that cylinders injector is leaking.A bad ignition module or ect sensor can also cause a no start.You can do the following test when the problem is occurring.Remove the air intake hose from the throttle body,spray carb cleaner or starting fluid into the TB opening, reinstall the hose,try starting the engine. If it starts and runs for a few seconds then dies,you've got a no fuel problem. If it doesn't start at all,you've got a no spark problem.

My 94 Toyota Camry 4 cyl is running really rough and stalling out once the engine warms up


Get rid of cold air intake and re install stock also sounds like your mass air flow unit is going out or your cars ecm isnt operating properly check air filter make sure its not clogged up then check all your vacuum hoses for cracks,dry rot or kinks making sure none are pinched causing vacuum to not respond.ok after this check the fumes from exhaust for color but it could also be catalytic converter even though it says air temp.when this problem occurs it can be number of things spray electric cleaner on wires as well and check for loose wires now take your time going over these things to be sure you accurately inspect this

Engine will not run, seems like it is not getting gas?


Spray carb spray or starter fluid into intake hose then try to start. If starts then suspect fuel pump and or fuel pump relay. If does not start check spark. Pull off spark plug wire and ground to metal make sure no fuel is present and be careful not to spark yourself, crank car while grounding out wire if no spark suspect coil, fuse, ignition control module, crank sensor, wiring, or computer.

Will not start--new battery,alternator,cam sensor,crank sensor,plug wires..gets fuel and spark,starter fine,cranks but wont start.


put a timing light on it. if in time then spray some ether in intake. if tries to run now its a fuel problem. make sure plugs are gapped properly. if you got timing,spark,gas at right pressure, and compression it should run.

BAD RUNNER


Check the fuel pressure regulator. Pull off the vac line to it and see if any gas is leaking out of the vacuum fitting. If you see any fuel replace the regulator.
