hi all hopefully someone can point me in the right direction,my car wont fire up for love or money,i dont seem to be getting much of a spark after a few hours or searchin on here im guessing it could be the crank sensor or the ecu,scanned it this morning got 18 fault codes !!! ive had 3 mechanics look at it n there puzzled really, checked all fuses relays etc faults are as follows


18010 power supply B+ terminal low voltage
16501 engine coolant temp circ low
16486 mass or volumeair flow circ low input
17834 tank vent open
17544 long term fuel trim add fuel bank 1 system too lean
sec air inj syst incorrect flow detected
17523 02 sensor heater circ blank 1 sesor 1 short to ground

Not a happy motor is it that one. Have you had a look at your ECU to see if its got wet?

Looks like fuse of bad earth wire of somthing...since you have a lot of short to ground codes...

Have you cleared the coeds to see what comes back..??

it stalled on the way home the other day then wouldnt start ,scanned it came up with these codes it drove fine this morning no probs at all,i thought the same thing so i cleaned every earth i could find but still no joy.ive cleard the codes but havent scanned it again gonna do it in the morning

18010 power supply B+ terminal low voltage

Im sure this code comes up when you disconnect the battery so could be a battery problem.

its all really started since i changed the battery bought it new from my work (vauxhall) but i had it tested 2 day n they said it is fine ?? couldnt get a 60 amp so they gave me a 65 amp

 

[23mjh]

damn! that's a hell of a list

tell me about it ive lost all faith in it! think my ibiza days are over when/if i get it sorted

 

[Mat]

get a correct amp... as for the SAI codes, that's pretty normal. Mine comes on a lot............
