Hi, have a 2004 2.8 Iveco daily tipper - 50c13. Put new inline fuel pump on it. Noticed tick over was 1500rpm but didn't think much of it. Next day tried to start and nothing - like battery dead but its relatively new. Put jump pack on it and started fine but still 1500rpm? Drove fine but speedo not working, rev counter stuck on 1500rpm, ABS and EBD lights on and no electrics like indicators and fan etc. Really weird as everything was fine until replaced inline fuel pump but can't see this having any connection???? |

35C12 2005 MWB DRW 3rd gen’ crew cab tipper F1AE04 85.3 kw 2.3 cc 16v. Weirdly wired. Is the inline fuel pump the same as the lift pump which is fitted near to the fuel tank? Fuel tank - filter - lift pump - filter - injector pump - injector. Bazil s has many posts on electrics. The wires are bundled, there are connectors at various points on the vehicle, the bundles go to/from connectors and to/from the various components. The wiring (bundles) seem to be organised into Engine, Consul display, Chassis , fuse/relay panel. Speedo, rev counter, indicators, are indicated on the consul display the wiring will be bundled to/from the consul to/from the fuse/relay panel - you may find a blown fuse there. The fan wiring could also be in that bundle and the fuse/relay on the fuse/relay panel. There may be connectors for that/those bundle(s). The fuel lift pump wiring is bundled on the chassis and there are connectors at the lower radiator area lhs. The wires are thin and numbered and coloured, the numbers can be very difficult to see. Fuse/relay panel is on the passenger side at the front, in front of the passengers knees. The placement diagram for mine seems to be a rear view which is confusing, it seems to be upside down and back to front where left is right or visa versa. Seems that when doing the in line fuel (lift) pump some wires were shorted (fuses/relays), some wires were pulled, some connectors were pulled, some connectors were disconnected and not reconnected. When the pump was fitted and connected up an electrical short was made/the connected wiring was not the correct wiring. https://www.youtube.com/results?search_query=fuel+pump+electrical+circuits Edited by ivecofd, Jul 26 2015, 10:17 AM.

35C12 2005 MWB DRW 3rd gen’ crew cab tipper F1AE04 85.3 kw 2.3 cc 16v. The pdf workshop manual is a pain to follow. In attachments is a simplified dwg of the wiring bundles which could be used as a guide. If you buy the workshop manual pdf which is on a CD you could follow the information available for the specific thing that doesn't work such as the fan. The terminology is weird as is the way it is put together. Stolen from: Rosiebear – IVECO - I nfuriating V ehicle, E lectrical C oding O ptional options. |

hi sorry but not an auto electrician so if not simple fix i'll hire an auto electrician instead of fucking about one thought when I disconnected the in line pump I didn't disconnect the battery and left it unconnected for a day while new in line pump arrived. |

one fault that causes engine to run at fast tickover (1500) is alternator/belt fault. If alternator output fails computer recognises this and speeds engine to compensate,had this myself, changed and sorted problem, not saying it is this but might be, or tensioner on alt. drive belt broken/siezed causing loose belt. check this first then check alt. output if poss. Dont know how this would reflect on other issues but mine went without warning. On my other iveco tensioner siezed and caused similar problem. good luck. similar to mine ! Italian Van Electrical Co operation Optional worked this out after owning each model since mk1 , havent made the jump to mk4 yet as all that Cat etc etc, but it will happen.

thanks - did think alternator might have gone as battery not charging but nothing to test it so will have to get someone |

35C12 2005 MWB DRW 3rd gen’ crew cab tipper F1AE04 85.3 kw 2.3 cc 16v. The reply: The pdf manual is a pain to follow was not sent in response to your comment - is as clear as mud. The internet stopped as I was sending it. So that had to be sorted. The internet now works again. This reply is in response to your comment - is as clear as mud. I was/am aware that my reply(s) is/are not clear. I was/am trying to help out. The affect you describe is complex. One could go back to the fitting of the inline pump and look for what is different/problematic there or deal with each affect singularly, perhaps find a common cause or and deal with each affect singularly. There could be a large amount of time involved to sort out your complex problem. Could be better if you had the workshop manual and could be specific about the problem(s). |

Well like I said just check belt and tensioner before throwing monies at it. |

35C12 2005 MWB DRW 3rd gen’ crew cab tipper F1AE04 85.3 kw 2.3 cc 16v EDC 16. Spent the last couple of hours looking for a circuit diagram on the workshop manual pdf and did not find one for the fuel lift pump or one that includes the lift pump which is also called Electrical supply pump and Electrical fuel pump by Iveco. I was hoping to find a circuit diagram from which it could be possible to trace links to the lift pump supply and the other problems that you encountered. Did find that fuse 47 which is 10 amp is for the lift pump. Well I am calling it the lift pump. However did also find that there are possibly two electrical fuel pumps one of which is high pressure. EDC Engine Diesel Control or Extremely Dodgy Circuitry as one person coined it. I found out one thing, that is I need to know which controller is fitted EDC 16 OR MS6.3. Just had a look and it's the EDC 16 on mine. I hope you have success in the fault finding. |

Sorry I didn't see this post earlier, yes sounds like lack of charge from the alternator, the ECU detects this and increases the revs to try and produce more charge. A cheap multimeter is a good investment, £5 and you can diagnose faults like this. Set it to 20 volts, when the vehicle is standing it should read 12.4 to 12.7v (12.4 is fairly flat) and 14.4v when the engine is running. From memory I remember the belt is a V groove type, apparently when work it can slip but mine was the alternator. I replaced my alternator on the street, the hardest part was getting a socket on the tensioner nut, when you push down it rotates the tensioner and allows the belt to go slack for replacing. You are not actually loosening the nut. I searched ebay by part number and found a higher rated alternator that fits the engine, as fitted to Ducato I think. It was noticeably bigger and 160amp ish rather than the standard 120amp, as I have 110A starter batt and 160A leisure batteries. Edited by Spooky_b329, Jul 28 2015, 05:55 AM.

35C12 2005 MWB DRW 3rd gen’ crew cab tipper F1AE04 85.3 kw 2.3 cc 16v. Found what is likely to be the lift pp circuit. As the connection in the relay is open when the starter key is in the off position there is no power from the relay 87 to the lift pp via wire 72032. So by leaving the battery connected and the starter key off it is unlikely that a short occurred when the lift pp was disconnected and the wire left off overnight.

Hi, Probably the earth cables between cabin and chassis, or between chassis and engine, are broken or faulty contact. Also check the battery poles! |
