Help and advice desperately needed...
I picked up a nice cheap Y reg Brava 80 with fogs, alloys etc but an engine that had apparently seized at 106K miles. The owner and his garage say it did run briefly afterwards (AA started it) but would then seize again. Got a matching 31K basic Brava engine from a breakers via the internet, was assured that they checked it ran before they removed it. Both engines were the later cam- and crank sensor versions with the deeper aluminium sump section.
My local engine garage did the swap for me (changed cambelt) and it fired up first time but cut out immediately with an ECU fault code and for the last 2 weeks it hasn't got any further. They have been all over it checking for bad connections, bent ECU pins, swapping cam and crank sensors, inlet manifolds / injectors, wiring loom, fuel, cambelt etc. It's been diagnosed by 2 different autosparks who could only say that perhaps the cam timing was out and the cam and crank sensors were disagreeing and the ECU did a safety shutdown as soon as it started to avoid damage. Timing has been checked and rechecked no problem found. The car will run if they spray brake cleaner down the inlet so clearly it is a fuel shutoff issue. I am assured that the error codes are cleared but reappear each time. The garage is about to give up on it and I'll be stuck - it should have been a simple plug-and-play swap.
Was there any variation between later engines where perhaps cam / crank sensor signals would not be compatible with the ECU? I am sure I started out with an electrically sound car and a mechanically sound engine, so why woun't it run? Unfortunately my local Fiat garage woun't take it on, and the local independent specialist went bust. Would a proper Fiat diagnosis with a workshop manual get me any further? Any ideas anyone? :bang:
Bothe engines have the same 4D 46550108 code on the head casting, car no. is ZFA182000 05127122, motor no. is 188A5000, version no. is 182 BT1AA26, spares no. is 5098499
