Thanks for the great question.

Does it quit like you turning the key off or more slower like it slowly running out of fuel?

Basic maintenance and no chip that we know of. Weworked on this pickup for the last 5 yrs.
Expert:  Fordanswerman replied 5 years ago.

Thanks

What are you using to test for codes and how long ago were codes checked? Do you still have the tester handy?

Thanks

Customer: replied 5 years ago.

Scanner is a OTC Genisys. Codes were checked today. We still have tester. We are a small repair shop, trying to keep the local trucks running.

Expert:  Fordanswerman replied 5 years ago.

Thanks

Does your tester capable of doing an injector buzz test on the injectors?

How does the truck run when it is running? Plenty of power? Misses?

Thanks

Customer: replied 5 years ago.
yes we did the buzz test tested ok truck runs great until it quits both going down the road or at idle

Double check to make sure there is not a physical chip attached to the outside of the ford computer located on the drivers side kick panel area. If there is a chip you will most likely see it taped to the ford computer. If there is one, remove the chip and drive again to see if this was it.

Next check for this:

Sounds like the under valvecover injector harness is falling away from the valve cover gasket. Remove both valve covers and look for the injector harness where it meets the valvecover gasket. If it is not all the way into the connector, then you need to install a new clip that Ford sells. The clip will keep this from happening again. This will cause the engine to intermittently stall.

Part Number 2C3Z-14A163-AB

this may be the problem seems odd that after the engine quits and we try buzztest it tests ok we can here it test all injectors and then one by one seems like the wire plug in is ok then
Expert:  Fordanswerman replied 5 years ago.

Thanks

Yes, if the harness is barely attached it can cause all kinds of issues and sometimes it will pass the buzz test and sometimes not set any codes because it happens so fast.

Let me know what you find. But don't rule out the chip. These can cause all kinds of weird issues.

Thanks

we did check for a chip see none this problem is not inter mintent it will idle for about 10 minutes then quit after it sits about 30 minutes it will start and run fine just like clock work

The only other thing I've seen do this without leaving a code of some sort is the IDM (injector driver module). But these are very expensive and would suggest checking the injector wiring first. If the injector wiring is fine and shows no signs of being loose then the IDM is the most likely cause of your issue.

Thanks

is the injector driver module and the pcm the same thing if not where is it located
Expert:  Fordanswerman replied 5 years ago.

Thanks

They are separate. The IDM is located up inside the drivers side fender well area. You need to drop down the drivers side inner fender wheel well to gain access to the IDM. If you find any signs of moisture in the IDM or the connector this is another good sign that the IDM is bad.

we will check and let you know what happens if we can figure that out still dont know seems to me that if the buzz test works after engine quits problem may be else where
Expert:  Fordanswerman replied 5 years ago.

Ok let me know what you find.

Just come back to this post.

Thanks
