You may have noticed alot of my whining in whats ruining thread so im hoping for some advice i'll try break it down as easy as i can. The Car: Vauxhall Corsa 1999 breeze 1.2 The week before this the car broke down in a similiar way but was started again and went fine for a whole week till: Breakdown 1 It started after i had finished college on a Friday it was 27c and the car had been parked in the sun for around 2 hours, I returned to the car refusing to properly turn on and instead just made the noise when you turn the key. What was unusual was that the car would still move in gear in that state even slightly up hill and i managed to move in about 5 car spaces before i gave up trying, the car just would'nt start. After my dad came to investigate he assumed an electrical problem and fiddled with some cables and connections, after 15-20minutes and no real aim of repair the car sprung back into life and was left idling we assumed it was fixed for the time being. i drove 100 yards and slowed down waiting for my dad to turn around and follow behind me when it began to idle very heavy and stall for no reason, after that the car would not start at all and i was towed to the garage. Solution 1 The mechanic assumed a dodgy cam sensor or fuel pump and explained how in the hot weather a faulty came sensor would cause it to cut out, after being towed for 30 minutes the car must have cooled down as it started first time in the garage. This was reinforced when the mechanic decided to test by dropping the bonnet and letting it heat up, as soon as the bonnet was dropped it cut out instantly without shudder, him and his colleague decided it was most likely the sensor and replaced it. Breakdown 2 I get back the car after the new sensor is fitted as well as an additional sensor that assumed was dead, the car starts temperature being around 17c at the time the car starts laboured and tired sounding i repeat it with the same outcome I go to pick up my mother from work and the car is going fine until i fill it up with £40 worth of petrol when i get back into the car to start it the rev counter goes up and dropped down to a heavy idle and stalls this is repeated until i add some revs were it goes fine. Once i get home i try the car again and works fine twice but third and forth time repeats the heavy idle until stall i eventually get it going with revs and take back to the garage the same day i picked it up. Solution 2 I find out the original mechanic has not fitted the cam sensor and his colleague did which he ended up doing wrong and it was kinking something im not sure what i believe of that but he seemed honest enough about it, i got into the car and it starts fine no issues i repeat still not problem. Breakdown 3 Only 1 hour later i drive the car to work and make it all the way to the car part where i was waiting at the zebra crossing randomly the car cut out and would not start again exactly like the first time! This is 4pm and not very warm at all, the car could move a little bit but not start properly i ended up pushing with the help of another man into a parking space. Solution 3 The mechanics come to the car park after i give the keys to my parents who came down to sort it out, they get the car started and take it back to the garage telling them it was most likely the fuel pump as they predicted before. Today i ring up and they tell me the fuel pump has not been replaced, that they have cleaned relays and put it through the diagnostics machine and it runs fine on two occasions two seperate mechanics have taken the car on longer journeys that my workplace and it has had no problems. Conclusion? Not convinced i pick the car up and take it for a drive similiar to the day it broke down in the car park with no problems i then took it on a longer journey to test it further no problems, left the car idling on two occasions like on the day it first broke down for 5 minutes with no problems, i intentionally stalled the car and restarted no problems. The mechanic told me "Its a bugger really because you can't tell whats up with it, when we took it out it went fine and we can't seem to see a problem we took relays out and cleaned them and other things" So im stuck wondering whats going to happen next? Does anybody have any advice on what they think it could be so if i take it back i could pass this on to the mechanic for them to check for me?
