..

it already has glo plugs to help starting
check that they are working
diesels need a fast cranking speed so make sure that the battery is in top condition
have a compression test done to check for correct compression pressures
have the injectors serviced because if they squirt instead of atomize then it make starting difficult

Had same problem with 6cyl. merc.
Started fine cold but wouldn't start when turned off hot.
Replaced spark plugs & worn dist. cap .Problem solved.

I have a 2001 Suzuki Ignis and I have a similar problem. When I start the engine 5 beeps are heard and the hazard lights turn off and on with each beep. Also after I have been driving for about 45 mins 3 beeps are heard and the hazard lights turn off and on again. However my engine does not stop running. I have asked people about it and they think that it has something to do with a lose wire in the security system? Any help would be greatly appreciated!

Any dash lights outages? Common wiring problem in some GM steering consoles cause this type of problem. Also I have heard of distubutor failures. You should see a SES (service engine soon) light on bad crank position sensors.

could be a bad crank sensor, a bad crank sensor will let car run for a while then shut down and will not start for 10 to 15 min. and it will repeat this cycle if not fixed.the crankshaft position sensor provides the ignition module and pcm with a crankshaft position signal. the module uses this signal to determine spark for each cylinder. the pcm uses this signal for proper timing of engine.

Ignition keys relearn takes about 30 min to do. 30-Minute Learn Procedure 1. Turn ON the ignition, with the engine OFF. 2. Attempt to start the engine, then release the key to ON; the vehicle will not start. 3. Observe the SECURITY tell tale light. After approximately 10 minutes, the light will turn OFF. 4. Turn OFF the ignition switch, and wait 5 seconds. 5. Repeat steps 1 through 4 - two more times - for a total of 3 cycles of 10 minutes. 3x10 = 30 minutes. The vehicle is now ready to relearn the Passlock Sensor Data Code and/or passwords on the next ignition switch turn from OFF to CRANK Important: Turn the Ignition Switch OFF. The vehicle learns the Passlock Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle. 6. Start the engine. The vehicle has now learned the Passlock Sensor Data Code and/or password. 7. With a scan tool, clear any DTCs if needed. History DTCs will self clear after 100 ignition cycles. Without a scan tool you may have momentary starter interruptions while history clears itself.

a bad crank sensor can cause this. shuts off while going down road, and will start about 10 min, later with no problems runs fine until it quits again. hope this helps,

Is there a security light on, if it is then you have the anti theft working thinking someone is trying to steal the car. If you have the second ignition key's with you try it.  If not try this, it takes about 30 min to do. 30-Minute Learn Procedure 1. Turn ON the ignition, with the engine OFF. 2. Attempt to start the engine, then release the key to ON; the vehicle will not start. 3. Observe the SECURITY tell tale light.
