Hi, New to the forum, so apologies in advance for any incorrect behaviour!
Have a 306 with similar problems. When I turn ignition the starter motor fires but car just will not start. Maybe because it's been sat for a while. Anyway, last time i did start her (2 weeks back), it took an age and I almost drained the battery. However, what I notices when turning the ignition on (not over), was there was no pump noise. Then after a very long time I heard the pump go on. It then fired up OK. So I thought I have a dodgy pump.
Hence why today I decided to strip the pump out and take a look. I applied 12v to the pump and shot fuel all over the place. Well at least the pump works. I refitted, but still no pump noise when turning ignition. Measured voltage at the Pump connector. There are 4 terminals 2 for the pump (+ve and ground), and 2 for the level indicator switch (+ve and ground). I only had 11v on one, all other terminals had zero. As the fuel level indicator is working I surmise that there is no +ve getting to the pump. Might be an idea to check this before buying a new pump! Checked fuses, not knowing which to look at, all looked ok. So think it's something else between pump and ignition. The found a thread about ECU and pump relays, but not much else. Any suggestions? Should I be posting this as a separate thread? Thanks.
