E30 1986 325e cut gas this morning
ok so this morning i was driving fine until i started to cut off and i was able to do only 20mph then it shut off i pull over and started up and it was fine so i keep driving for about 10miles and it did it ones more time, this time it would not turn on. motor crank but wont turn on. I notice my fuel pump would not turn on at all until i jump it were the relay goes. I got the fuel pump running but with jumping it with the wires but still wont turn on. i know it haves gas but my sender unit is not working right . would my sender unit have to do with the fuel pump not working. please help

fuel pump relay, fuel pump, pulse sensor, and in your case, e30 ignition switch failure is common.
just places to start looking. i used to have to pull the key back a little when the starter engaged to get ignition on my 88. but it was a cabro and was exposed to florida weather.

yes, the ecm can't confirm that the engine is turning (input from pulse sensor)it will de-energize the fuel pump relay after a few seconds. It is a safety thing, if you had an accident or a broken fuel line you wouldn't wantthe fuel pump to continue to pump gas all over the place.
