My buddy has a 96 f250 with the 7.3 power stroke diesel, and the damn thing wont start. Any suggestions on where to start looking for a problem. Any help would be appriciatted, and thanks in advance,
Bill

 

Make sure it's not out of fuel.
Check the glow plug system, make sure the controller and plugs are good.
both batteries have to be fully charged because the PS needs to crank very fast to start.
check the engine oil. The PS uses engine oil pressure to pressurize the injectors so make sure the oil is changed often and the level is at the Max line. If it is low on oil it will not start due to lack of oil pressure in the cylinder head.
If all that stuff checks out then you need to start running computer tests.

GOOD LUCK!

 

I went over to his house yesterdayand he had a charger out charging his battery. He charged it for a while and tried to start it but it would just turn over really slow.

 

Remember, the PSD has a 100k warranty.. If your under that, let the dealer have a look..

 

Think I know a cure. My dad had the exact same problem.
ended up being the starter I know it sounds odd but a diesel engine has to crank over very fast to start. Fixed my dads problem hope it helps ya.

 

Hey guys thanks for all the help, we have tried everything and it still wont start.

 

I have a 2001 F250 PSD that also won't start. It has been in the shop 4 times. They checked the glow plugs, batteries, compression sensor, and changed the oil to a heavier weight. They seem stumped. It is getting about a 10 to 15 second crank time, then eventually starting. Even though it eventually starts, it is wearing out my starter. It was slow to start when I bought it, but the dealer assured me that it was because it had been sitting on the lot for a while, and that they would replace the batteries if it continued......4 trips to the service department later it is still not starting right...HELP!
