Hey you guys doing? I have a 88 325is that just died out on me and doesn't crank over.. I replaced the fuel pump rely, the fuel pump and nothing.. Is there anything else I should check? This is driving nuts! Car ran fine before.. Somethings it'll take a few minutes to crank over but it always started .. And it has just cut off and died while I was driving.. NEED HELP!! Thanks in advance

Starting checking stuff man.

Crank sensor resistance ~500ohms

Check alt and battery
