hard to stary after driven awhile
 

No issues starting it cold. Forgot to mentioned that I changed the fuel pump relay as well.
So i'll look for that fuel valve tomorrow.

If it starts good cold but very hard hot there is a good chance the injection pump is worn out.

Next time it is hard to start hot pour water over the injection pump and then try-if starting improves by a lot the injection pump needs rebuilt/replaced.

hard to start when hot
 

Thanks racer. Where is the injection pump located?
Once again thanks.

The injection pump is at the frt of the engine in the center right behind the oil fill spout under the pipe that the air goes in the engine from the turbo.

Well it was hard to start today after I drove it 70 miles. Poured water over the injection pump and it started. !

Alot of money for a rebuilt Injection pump+ labor!

Shop around for a rebuilt pump and then google the vendors you choose.

There are a lot of poor quality rebuilt's out there and the net gets all the bad reports.but few of the good ones so if you get a lot of threads to read it will probably mean stay away.
