Fuel pump working? (can you hear it when the key is on?)

the car will run until you shut it off then it wont start unless you spray it with starter fluid

could be a cold injector valve. replace it or hot wire the external butron for it.

i have replaced the cold start valve and the blue temp sensor , where is the external button for the cold valve.i also noticed the fuel pump

Be careful, there are 2 fuel pumps back there. One internal to the tank which works as a supply pump to the external fuel pump by the tank. If either one of those doesn't work then the engine may not get fuel. Also, make sure your fuel pump(s) relay is working. Those can sometimes fail on you.

Can you give us a run down of what you have tried so far? It will help us to understand so that we can help you.

Thanks,

Eric

it was the crank sensor
