starter clicking and electric warning on dash with stop sign rcz diesel

[danieldavid]

hi anyone who has suggestions that might help solve.

left car parked unlocked for few days, wouldnt start, i charged it at low power on charger and it just started, went for a 20 mile mostly fast drive and thought it would be fine, but again only just started on the second attempt, stopped 5 miles later to get diesel and couldnt start it. thankfully i was right next to an mot garage next door to fuel station and they thankfully helpfully jump packed it and it started. Ive charged the battery to 12.5 volts, ive got it nose to nose with my other rcz diesel and jump leaded the two batteries together, the other one o know starts fine, but still wont start. ive tried a few times to do bsi reset, but it just keeps clicking once loudly when i try to turn over the starter. I think the battery is fine, but for some reason the jump back at that garage seemed to start it first time,m i know they deliver loads of current, but i cant start it so far even with two bateries together. i found a loose nut on the fuse connections of the bpcm, i think thats what its called, it sits on the battery, im guessing it cant be a fuse as the jump pack started it, and cant be the battery as the other rcz starts and ive got them connected together with heavy duty jumpy leads, ive thought of swapping ober the bpcm module with my spare rcz, are there any obvious things i should check, when i drove it the other day, there was power shortage to everything, even though battery fine, warnings for power steering and abs esp which are all electric driven, the power steering was even going heavy. im sure ive reset the bsi correctly from procedure, any suggestions or ideas welcome, thanks ps i cant think it could be the fuse for the starter motor relay as it started with the jump pack the other day by garage.

on the fuse diagrams the battery charge, power steering and abs esp fuses are all in the bpcm unit. i had this happen nce before a year ago and someone jumped it from a pack, and it just charged up normally after a drive, but this time its not restarting so far. so the bpcm unit wasnt faulty a year ago, im guessing it night be a software issue or code, i need to get software for my opd2 elm little scanner, i only had it on windows xp and my last xp laptop isnt working as its so old. has anyome had to delete codes before to reset, i thought just a bsi reset is supposed to work, i dont know if any codes would be within obd2 list, or extra ones in other scanners.

i checked the starter fuse and bsi fuse but they look fine. i saw a vidoe somewhere if i can find it again where the person removed a plug of wiring for bsi on fuse box under bonet to get it to start on a peugeot. i can try to find that video, but he said that the bsi was carrying out checks that could prevent a start from occuring.

sorry bpga not bpcm

i tried bridging the screws with wire on the bpga as it says to online to see if it then starts, but it didnt. Whats even more strange is that theres about 13v across the battery and between live battery and chassis, but only 1.7 volts on the bpga, which rises to 3.5v when i turn the ignition on. I checked the one on my spare rcz and with ignition off, all the connections were at zero. That other rcz starts, though it does pull up the error message about battery, the previous owner had reset the bsi to clear that, and interstingly the passenger window doesnt work on that one whuich ive read can be a result of the reset pricess not competing properly. the joys of french car electrics. in case anyone has experience of this issue, thanks

ps, if the starter is clicking or the relay is clicking, does anyone know if the relay is seperate and might have failed, or if the starter might have failed if it makes one click
