check and bleed air from the fuel system. check for fuel level in the tank. run the fault codes to check for cam/crank position sensors and broken timing belt.
Hi Peter, If the vehicle turns on the starter all the time, and sometimes starts and other times fails, check the fuel filter for leakage. Sometimes air gets into the fuel system. When it gives problems, open the bonnet (hood) and have someone pump the pump on top of the filter housing. If it feels soft when beginning to pump, I would suspect either a leakage on the fuel line or the filter housing. If you need to replace the housing and filter, remember to fill the replacement filter with clean diesel fuel first. the glow plugs can also cause problems if one or more have burned out.

Basically this means that there's a problem with the Mass Air Flow (MAF) sensor or circuit.
You will likely not notice any serious driving problems, but there may be symptoms like a general decrease in power or sluggishness. Causes
A code P0100 may mean one or more of the following:
* The MAF may be disconnected, or a wiring connection may be bad. * The MAF sensor may be faulty.
Possible Solutions
Use an OBD II Reader (or go tou your local parts store and they will for free) and reset the code and see if it comes back. Then start with the cheapest, easiest repair procedures:
* Check the Mass Air Flow Sensor wiring/harness is connected properly and that there are no broken / frayed wires. * Unplug and reconnect the MAF wiring harness a few times to clear the contacts. * Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information). * Replace the MAF sensor.

Normally, only 2 things stop a diesel from firing: 1. no fuel 2. not enough compression
No fuel can be caused by (obviously no fuel) or a failed fuel pump. To test, have someone turn the engine over and then sniff at the exhaust - does it smell of unburned diesel? (If you've run out of diesel recently, you may have an airlock in the system, this needs bleeding out.)
Not enough compression needs specialised equipment to test - that's a garage job.
Ok well the glow plugs on a diesel have nothing to do with the engine firing. All the glow plugs do is heat up the combusion chamber on cold starts. Diesel engines fire using high compression. An oxygen sensor won't cause the vehicle to not start and your diesel doesn't have one of those anyways. It could be a fuel related issue. (pump, line, pressure etc.) Have you it scanned for engine DTC's? But based on your knowledge of your diesel vehicle i'm going to suggest you take it to a shop.
