08 250 spins over dont start ,,this morning it started for 3 seconds then stalled and won't start just spins over is their a fuse i can check?

 

There are many fuses you can check.
How do you plan to do this?

If after you get done checking and you still have the problem,

We need to know 2 things, is the engine getting fuel and is the spark available ?
After a few cranks to try to get it started ,
Remove one or two spark plugs to determine if they are wet or dry.
If wet , fuel is getting to the cyls. , if dry it is not getting fuel.
Let us know which result you found, thanks.

 

found it it was a fuse thanks guys

 

some times the engine gets fuel and some times not ,,,fuel pump,,were changing that now so will see thanks for the info

 

Before jumping the gun, and possibly replacing a good fuel pump assy, suggest you make sure all power and ground connections are clean and tight.
It it not pleasant after you go through all the work of replacing a fuel pump assy to only have the same problem.

Some systems have a fuel pump driver module that controls fuel pump operation. Good move to verify that module is working properly and has good connections.
Here again if a good fuel pump is replaced and the module supplying power to the pump ,is not doing it's job, the problem will still be there.

 

Were still working on it their was no fuel presser so new fuel pump next thing but thanks for the info

 

If the pump is operating and no fuel pressure, yes, could be the pump motor.Could also be stuck open pressure regulator , which in this case replacing the entire fuel pump module is required.

If the pump is not operating and no fuel pressure, might be a good idea to make sure power is getting to the pump. If it is not, ,,,install new pump and still have same problem., that hurts.
Trying to help you from replacing a possibly good fuel pump.

 

I hear all that well its always trail and error were at that point now thanks ,,,the soga goes on
