CRANK but NO START " MYSTERY"
2007 E350 Sport Edition: Current mileage 178,000+
Problem: Car will start when cold but after 30-40 minutes driving or on idle, it wont restart. It will restart
after 20-30 times trying. It started 3 months ago and now still idle in the garage due to
this unresolved "mystery". I dont have the ("$$$ dinero) to support the 'stealership" so
helpful suggestion from fellow members is badly needed.
NO CEL or OBD error codes displayed or generated with this problem
What I have done: Changed or replaced the following parts:
1. CPS( Crankshaft sensor) twice
2. Coolant Temperature Sensor ( Mr. Konistiger helped identify the sensor)
3. Secondary Injection Pump, fuse and relay due to P410 error.
"Weird" noise and wont stop even when engine off. (resolved)
4. Camshaft magnets (2) left and right) and positional sensors( also 2)
5. Fob (key) new batteries
6. Battery tested OK 12V
7. Fuel pump fuse and relay ( trunk compartment,driver side)
8. Engine oil/filter and air filter
9. Fuel pump and filter changed July last year
10. ECM fuse not blown and pulled,visually OK
11. Neutral Switch seems ok, shifter move with key on
12. Fuses in the trunk, near the battery visually ok.
Possibilities which I have not done:
1. Fuel Pressure and leak test
Visiting technician just assured me its ok but did not use the fuel pressure gauge to measure
50-60 psi with engine on or off. Just disconnected fuel line and noticed fuel present.
2. Bought brake switch but not installed yet.
3. Another fuel pump/filter or fuel pressure valve test?
4. Injectors seems ok, no wetness along the rail
5. No spark test with the injectors yet
6. Engine control module and other modules which is/are defective?
( last resort to dealership equals $$$-$$$$)
Any suggestion or solution is greatly appreciated. Never had a problem with this car since replacing the fuel pump and filter last year. Thank you all.

You have typical symptoms for bad CPS, so what CPS did you put in?
Suppose observing tachometer during cranking can tell bad CPS.
I wonder is Torque app would show rail pressure on this car, so you could monitor it the easy way.
