Recently changed the fuel tank on my e28, it's a 518i 1988. Now sometimes when i try to start the car it turns over and over and over without actually starting, can do this for a good while and eventually the battery will be flat. Jump start the car and it starts first time. Then other times, it's starts on the button no problem at all. It still drives and responds under acceleration just as well as it used to (as well as a 1.8l tank responds) the problem doesn't follow a pattern, it can be first thing in the morning, after I've drove 20 miles in the sun or 60 miles in the rain, length of period left between driving doesn't seem to follow any pattern either. Everything was reconnected correctly (it's pretty hard to get it wrong) the only difference being the fuel tank and the fuel level sensor (it came with the tank and scrap man stole my old tank off my drive before I took the old one out) the tank wasn't new so neither was the fuel level sensor (assuming that's what it is?) I've read the Haynes manual and my tank doesn't appear to be in there. It has one 3 prong connector and 2 hoses. Also I think but I'm not sure that when I started the car I used to get all the green lights on my dash, now I only get 2? (I did say think as I'm not 100%) I'll link pics to show which lights I mean as googling that only brought up info on how to turn my service light off with a piece of wire. Any help would be a appreciated
