I have a 1995 7.3 liter turbo diesel in an e350 ambulance...I was having an issue with my e350 dying while in drive and at idle...now If you increased rpms prior to stopping and while stopped of course it would keep running which is what i was doing...Then one morning in an effort to keep it running i manually down shifted while exiting a highway and onto an exit ramp....Once at the bottom of the Ramp the vehicle quit and has not started since...I checked for any codes and no codes show up on a tester...I checked the accelerator sensor and it checks out fine....I replaced the fuel pump 8 months ago looking for a seperate problem which was a camshaft sensor problem...I have changed the fuel filter recently....????Any help would be greatly appreciated
Would Quit in idle in Gear....Then quit completely and won't start on 1995 Ford E-350

This is a long shot, since there could be alot of things causing this issue. For whatever reason (leak, service, water) there could be air in the fuel lines that make it run that way. We had one in about 2 months ago for a fuel leak, and it ran that way for hours, unitl we bled the system by cracking open each injector. Not many problems on that engine that are not fuel related. Good luck.

I'm thinking the injector control pressure (ICP) is in question. And / Or the fuel injectors themselves could have wear issues. The high pressure oil pump needs to be checked to see what kind of oil pressure it is producing. The ICP should be checked, the IPR (injector pressure regulator) should be checked. Also, there are wiring harness under the valve covers that could be suspect - they feed the injectors.
