SOURCE: 2003 sentra wont start cold unless plugged in.

I'm having the same problem. Sentra 2003 won't start unless giving some gas with the pedal or plugging it in. Battery is good, fuel pump and fuel rail pressure sensor has been changed.

I think it could be due to coolant temperature sensor. Don't you think?

Why will my 1998 chevrolet cheyenne not start unless primed after sitting overnight

by primed are you supplying a fuel source if so then the car is not getting fuel to burn. this indicates your fuel pump is bad and needs replacing and change the fuel filter also. the reason the pump won`t work sitting overnight is that the pump can`t build up enough pressure possibly because the fuel pressure is not being held, but after the first start up the system can maintain enough pressure to start through out the day. you can have the fuel pressure and volume checked with a gage when the problem occours to verify.

Why does 2001 gmc jimmy won't start unless primed why won't 2001 jimmy start

you say it won`t start unless primed I take it you have to supply a fuel source. if so check fuel pressure as the pump maybe failing.

Engine crank but will not start, checked fuel pump and it's not priming up not even after sitting overnight

You didn't reset the fuel safety shut off,
It only opens in an accident

The red button just flops around when the switch is closed

You have to provides details for us to suggest something

Checking the fuel pump-HOW details,test results,scan tool data,
pressure gauge,hear it run?

Spark-check for that
Check injector pulse?
Checked fuses & links

Battery any good-always start there unless you have a flat tire

If you can tell us through the proper testing that the pump
check valve has failed & you loose fuel rail pressure when it
sits,then you already know the answer & what to do

How would a fuel pump build pressure (not prime,there is non
of that) if the pump is turned off over night or key off?

My suburban has to be primed to start

There is a separate circuit and relay that primes the fuel system when you start the vehicle. If you sit in a silent location and turn the key to the ON position (without cranking), you should hear the fuel pump run for about 5-6 seconds. This is to bring the fuel pressure up in order to let the vehicle start. Then the normal pump circuit takes over. Sounds like your priming circuit is not working. I would try the relay first.

I can start the motor with the engine heater plugged in,but it starts to stall out a little faster the longer I try to troubleshoot it. I've replaced the fuel filter.

If your talking about a 7.3 diesel then you have injector problems..when they alot of miles on them,they start to lose their oil prime when sitting overnight..Then it causes a hard start or no start..unless you plug it in,and then it will run rough until it get warm..only way to realy diagnos which injectors is to look at scan tool and do some different tests
