Question about 1997 Ford F350 Crew Cab

1 Answer

1997 powerstroke 7.3 wont start

My dad just had a guy work on the truck. The guy said he turned up the injectors to run 65% instead of 42%, and he did some tuning to the turbo to make it spool faster, and replaced the gasket on the water pump. He was driving it back to my dad's house, and the truck quit and wouldn't start. I am wondering if it really is possible to do the things to this truck the guy said, and if anyone has ideas on y it wont start. it turns over fine. I am thinking its that safety switch that is supposed to be under the dash or under the hood. i appriciate all answers.

    could it be the IDM? i am not exactly sure what this is but it was suggested. My cousin is a mechanic and he thinks it is the crankshaft positioning sensor. my dad wants to try any of these before he takes it back.

    its possible but unlikely to have happened just after having it worked on and all the odd adjustments made to the truck

Diesel wont start 05 powerstroke

check the injectors or replace injector tips . It appears that you are loosing residual pressure in the lines or injectors and they are not atomising until the air is removed.

Ford had a lot of problems with this engine. Most diagnosis requires a factory software scanner or one that can interface with the FICM module (fuel injector control module) Now you can perform injector buzz test and glow plug tests. If you can get running then also do a power balance test these test check fuel injectors statically and dynamically with the common rail oil pressure control sensor. These FICM modules are famous failure parts. Napa auto can get them.

According to my Haynes Diesel Engine Repair manual this is a list of possible causes.
1.Slow idle incorrectly adjusted
2.Fast idle is inoperative
3.Restricted fuel return system
4.Glow plugs turn off too soon
5.Insufficient fuel suuply to injector pump
6.Injector pump malfunction
7.Incorrect, contaminated or poor quality fuel
8.Air in fuel.
The manual is part number 10330 anywhere they sell Haynes manuals ($20). It has a very good section on the 7.3 especially if you don't want to spend money at a diesel shop every time it needs work. Hope this helps.

1995 f350 7.3 powerstroke losing oil I believe oil is going into fuel tank. whats my problem?

You have a bad Injector O-ring. It is letting high pressure oil over power the diesel fuel pressure.

O-ring kits are available for $7 for each injector.

Put new glow plugs in ran fine for 1 day now it wont start..

You may want to surf around on some of the powerstroke forums for detailed answers, but I know the powerstrokes use oil pressure to control the injectors so you may have some problems with the high pressure oil pump.
Again, it is just a guess. I just wanted to point you to some of the Ford Powerstroke forums which may be of much more help for you.
Good luck..

How do i change glow plugs

If you are sure the glow plug relay and timer, which looks like a starter relay sitting on the intake manifold, are good. The glow plugs are located under the rocker arm covers between each injector. I would recommend purchasing new rocker cover gaskets, which incorporate the wiring harnesses for both glow plugs and injectors. They can be reused, but they will generally start to leak oil before long. The injectors are pretty easy to identify, they're the big square things with the electrical plug. the glow plugs have a single wire running to them. if I can recall they require a 10mm hex. hope this helps.
