I believe the vehicle to be in" limp mode" which means that you have a sensor or something going or gone bad. raise the hood , turn the headlights on then go take the ground cable off of the battery and then take the positive terminal off. Leave them off for say 30 minutes then turn the head light switch off and put the battery cables back on in the reverse of how i told you take them off and see if that fixes your problem!

check the ignition system, when was it last serviced? could be it needs new plugs or leads? Fuel pump changed but is the fuel system in good order. A GOOD local mechanic should be able to advise you on the issue

if the fluid is full then the only thing it can be is either the trans range selector switch, the trans computer or a mechanical failure in the trans, u will need the system tested for any stored trouble codes.

behing right loes kick panel

have a load test done on the battery as there appears that there is insufficient current to start and supply to the ignition at the same time . Possible dead cell

clean the throttle body inside. check the idle airspeed control valve,(iac) is ok....check the sensor wires located on the air cleaner assembly if the air flow sensor is gone,it will not run proper. start with a good tune up ....correct plugs,wires cap rotor.fuel filter and pcv valve..check all the vacuum lines are tight.

sounds like a clogged converter for sure.

check egr valve vaccum hoses and idle control valve

Can you give some more detail? Will it crank? Do you hear any noises? When the car is warm/hot/cold are the symptoms different?

That is very doubtful. The best thing to do is have a ****** repair shop look at it as guessing gets you nowhere.

I think it is the transmission that has failed.

your fuel system is cis i would look at the injectors there known for that issue also the cold start solenoid can cause those types of problems but leaning towards the injectors

Typically, when a water pump fails, it fails because it is leaking. You will lose the coolant and your car will over heat. We must not be on the same measurement ... where I am, coolant temp of 60 is very cold. Keep an eye on it ... add water/antifreeze as necessary. Watch for leaking on the ground or on the motor.

there are short circuit somewhere ,check that no wire touch car body in the switch.
