Answer for 2007 E350 120,000+, car starts but won't turn over. Had intake manifold replaced new by dealer few months ago. Could fuel not getting to engine have anything to do with this?
The first thing that we check when a car comes to the shop and turn but doesn’t start is a code for CPS (crank position sensor), if no codes presented, which is very unlikely in this situation, we start normal diagnosis routine, we check for fuel pressure, spark on plugs and compression at combustion chamber however, car not starting can be relayed to many other things, for example, bad ECU.. timing chain broke…,fuel pump not working…, bad fuel..bad fuel filter, ignition coils fuse burnt etc…. start with the easy steps if you still can’t find the reason have it checked by a professional. Thanks and keep us posted for the outcome..
