1987 bmw 325 2 door won't start fuel or relay
I just had a new cd stereo installed at some stereo wherehouse 2 days ago. I had the original bmw tape player but wanted new because it was old. I was driving on the freeway with 3 friends in the car and my car just didn't get any acceleration when i was going slightly uphill on freeway. I have a manual trans. and tried to jump start while on hill but it wouldn't spark. i got almost a turnover and started but then again wouldn't get any gas. i didn't flood it and the battery wasn't dead I have had this happen a couple times on the freeway but i was able to push start by turning off still coasting and it would start. but luckily i was not going uphill. can anyone please help. ive noticed 2 fuel pumps. dont know where the fuel relay is or if i should just change the filter or pump!!
Thanks for any advice;.\\
