I have little/no mechanical expertise so please bare with me!
I have a 2001 Astra 1.4 LS mk4, which I've owned for a year and a half. Just over a week ago, my car developed a fault - About 1/2 a mile from the house, I was about to pull out at a junction and the car just cut out. I tried to start it again(was ticking over, but not catching). Eventually it started again. Then after roughly the same distance, same thing happened. When I got it started again, I decided to head home, so at least I wouldn't be stranded. It happened another twice and on the last time, just round the corner from the house, I lost throttle response. It came and went until I finally got home.
Got it recovered to my local Vauxhall dealers who said there was a code stored, and was told it was either a fault with the fuel pump relay, fuel pump or ecu. They started with the relay, and when they replaced it decided it must be either a faulty ground wire or the ecu. Now, they are going to check over the ground wires, and will get back to me when they have. If all are fine then I'll be asked if I'd like my ecu replaced. They also mention that even if they do replace the ecu, the problem may not be resolved.
So here's my problem:
I paid £2000 for the car last year,
I've been told an ecu will be roughly £600+vat+labour, then I've got the labour and what they've done so far (not sure how much this is though) I reckon I'm looking at at least £1.2k total?
Is it worth paying this (if ecu necessary), if there's a chance it may not fix the issue?
If not, how could I get the most money for my car in it's current condition?
