Hi guys!
New to the forum and thanks in advance for any helpful advice.
As the title says my car won’t start. It all started a week ago. I hear some noise that where unusual. The engine coughed and I ran the OBDII reader. It gave me a couple of faults. I got that the lambda sensor was faulty and the engine got to much air in correlation to fuel which could also imclude the MAF.
I cleared the codes and gently cleaned the MAF and put in a new filter.
While waiting for the car to give me the codes again new (!) codes arrived.
This time around the engine (at first) sounded good but when the next codes came it started to sound really bad. I checked the codes and it gave med several new ones. “Misfired cylinder” 2/4 also Crankshaft Position Camshaft Position Correlation Bank 2 Sensor 'A'.
After this the engine just gave up and won’t start again. It’s like it doesn’t have the power to start.
I got juice from the battery but have no idea on where to start.
The car is a Vauxhall Antara 3.2 V6 -09 it has run about 60000 kilometres (Swedish)
Nothing happens if I disconnect the battery.
I’m wondering if perhaps the coils that made the cylinders misfire is at fault. How can I check these without the car running?
Must confess I have no idea. Seems like you may have a timing problem, crankshaft/camshaft position sensor. I would check these first before you go further afield.
I’ve checked tonight and the camshaft/crankshaft is ok, the sensors is ok as well.
After a lot of checking I now know the problem but not what’s causing it. The engine doesn’t get fuel!
The fuel pump is working, the ignition coils are ok. But somehow it’s not letting the engine get any fuel.
No idea, I'm not familiar with the V6 petrol engine. Someting is stopping fuel being injected, just check everything you possibly can. Have you disconnected something, did you change something when these problems started.
Im usually adept in fixing my car but I bought this 1 yr ago and even though it’s old it’s in very good shape and have been used very little.
This problem came fast and it basically just gave up on me. I’m starting to believe it’s the ECU but then it shouldn’t crank the way it does (I think?)
I have gone over all electrical components twice and found no breaks or disconnected.
I have a fully charged battery, fuel in the tank and so on. The next step is to start taking the engine apart and look for faults....😫😫😭
Hi I don't think the ECU inhibits cranking. I wouldn't take the engine apart, seems a bit extreme unless something tells you you have a problem with it. You could do a compression test on all 6 cylinders that would tell you if you have an engine problem. Check you have a spark on one of the spark plugs by connecting to the HT lead and placing against the engine, then crank, just dont hold the lead or plug whilst cranking. Have you checked to see if there are any codes in the computer via the OBD port ?
From the start I had several faulty codes. It’s been a nightmare since there where over 10 codes.
I ruled most of them out since the wouldn’t intervene with the engine that way.
I’m currently trying to measure the fuel injectors and see if they are at fault.
Does anyone know how I can get a hold of the electrics schematic over the wiring for a Z32SE petrol engine from 07-09?
I can spot 4 of them but the last 2 I can’t really be sure off.
Hi, I might be talking out of my backside here, but have you checked to see if the Timing Belt is intact. It's just that over the years, I've had two timimg belts snap on me with Ford cars, one of them less than 6 months old, and if the engine is cranked over with the belt broken it can cause all sorts of problems such as mis-timing, mis-firing and the ECU sending wrong signals to the fuel pumps/injectors. I know it's a shot in the dark, but as the vehicle is old, the belt could have deteriorated.
Best of luck with it anyway.
