My Iveco TurboDaily camper has a starting problem. It is an Iveco TurboDaily 35.10 series 2 built in 1991. It is 2.8L with motorcode 8140.23 ID/TC (direct inject and turbo). Current mileage is 300.000km. The first 100.00 were as a van, the last 200.00km were as camper. Cold start never gives problem. A touch of the ignitition key immediately starts the engine. “Warm” is giving problems. The starter motor spins, but the engine doesn’t fire up. A small puff of start pilote is enough to get it running. The problem occurred once a couple years ago, but it seems to be getting more structural lately. Driving 25km after a cold start is mostly enough to get the problem. We did a test by driving/stopping for 7 to 8km and trying to start. At 25km the first failed start occurred. However it also happened that after a successful warm start and stop (without driving), it would not start again. Coolant temperature is between 70 and 80 degrees C. Which is what it always was, it never is higher. Once started with start pilote, it immediately runs fine and there is no power loss. I am not sure it is a “warm” starting issue, since I am not convinced it is related to the engine temperature. Actions that are already done at the garage: 1. Compression test -> Ok 2. Valve clearance -> OK 3. Injection pump timing -> OK 4. Injectors -> OK 5. The fuel system was flushed with Forté 6. The electronic fuel cut off valve on the diesel pump was replaced 7. On the positive lead on the fuel cut off valve a bypass was made (original cabling gave 11.8V, with the bypass 12.4V). All above actions did not reveal or solve the cause of the problem. The motor function seems to be fine. At this moment the main suspect seems an intermittent problem in the fuel supply, for an unknown reason. Has somebody ever experienced similar problems? Thanks in advance for your experiences and advice. |

When hot, try pouring water (watering can) on the high pressure end of the pump to cool it down. About 10 litres worked for me. Try not to splash it all over the engine as you only want to test the pump. Then try to start it. In my case starting was much easier, just like from cold. If that is what you find then it's time to look at the injection pump. I'm going to have a new hydraulic plug fitted on mine. If that doesn't work then it's time for an overhaul. |

I'm not sure if this applies to the older 2.8's as this advice was for a 2003 2.8, but hot starting problems can also be caused by the Crankshaft sensor failing. I think the crankshaft and camshaft sensors are the same and can be swapped over to test them. http://ivecoforums.com/topic/8762875/1/ |

No speed sensors on the old mechanical 2.5/2.8 engines, so this won't work... |
