I own a 1987 760 Turbo wagon. My car has been sitting for about a month while I was doing some unrelated suspension work to it. When I parked the car a month ago it was running perfectly, now it wont run ? Yesterday I tried to start the car and it would not start. I checked for spark and that was fine so I began looking for fuel related problems. I checked my pre pump even though it was running and found that the bellows hose that connects the pump was ripped. I ended up replacing the pump and the hose because I came into lots of spare parts. The car was still hard to start, but it started, but now is running awful. I replaced my main fuel pump and checked the FPR and radio relay. Still runs terrible. I ran through all my normal tests and cannot find the problem ? The car is hard to start, it stalls and will not keep running no matter what RPM. It is running very rough as well. I have swapped FPR, checked AMM, checked for vacuum leaks, cleaned Throttle body...nothing has helped....Its almost like the engine is being starved for gas, but there is plenty of fuel pressure and a good flow of gas Any thoughts or suggestions would be appreciated ! Thanks, Mark
