My car will crank only when I remove the negative cable (removing error codes) from battery for few minutes and then reconnect. Runs great. When turn off key. No start. The car will lock and unlock...but I suspect the security system. What, if any, mechanical error code would prevent the engine from starting? I bought a Peake R5/FCX(3) code tool. Properly used, will that find my error code? DWA code would not keep car from running...and my car will run.
Car won't crank until remove neg cable from battery. Why? on 1999 BMW 740iL
