20 Most Recent 1986 BMW 5 Series Questions & Answers


You will need to check for fuel pressure or dirty filter. If you do not have fuel pressure; be sure to check fuses or any relay pertaining to fuel pump (if electric). If fuses and relays are good check or replace fuel filter. If the fuel pump is mechanical disregard fuses & relays and check or replace fuel filter. If this does not resolve the problem then the problem could be the fuel pump if mechanical, If its an electric fuel pump it could be a fuel pressure regulator, fuel pump, crimped fuel line or other wiring issue.

These are the most common things I run across, oh, a crimped fuel line can cause the problem in either case electric or mechanical. Hope this helps in some way, been awhile sense I worked with an older car.

It sounds like either the throttle position sensor or the mass airflow sensor are bad-the TPS can be checked with a digital meter, it should give different voltage readings as the throttle is opened with the engine off, key on. The MAF can be cleaned with MAF cleaner, or will need to be replaced. Another, although less likely possibility is a clogged fuel filter.

I am not familiar with this model but have experienced a similar nightmare on a very model. I suspect that the child safety locks are set which is stopping you opening the doors from the inside and the outside handles are not working because the latches may have been set in the locked position.

IT'S VERY EASY TO RESET THE TRANSMISION'S COMPUTER. HOLD GAS PEDAL DOWN. TURN THE KEY TO THE NUMBER TWO. CONTINUE TO HOLD THE GAS PEDAL DOWN FOR THIRTY SECONDS.RELEASE THE GAS PEDAL AND PRESS THE BRAKE PEDAL FOR TEN SECONDS. NOW YOU CAN TURN THE VEHICLE ON. THAT SHOULD TAKE IT OUT OF SAFE MODE

You can have a problem with the shifter cable. It will only allow it to crank and start if it's in Park or Neutral and it may not think it is. Move shifter through its gears one at a time and see if it tries to crank. That is assuming it's an automatic transmission. If it's a manual it could be a clutch pedal switch. Could even be a starter relay or loose wiring between relay and starter. Good luck.

The SRS light is on because the airbag system has developed a fault and is turned off. When the problem that caused this is diagnosed and repaired the light will extinguish itself. Right now you have no airbag protection in a crash, this could cause you serious injury or ***** how much is your life worth, get it repaired. I remember well the horrible damage to the human body before safety features like Airbags and collapsible steering columns to list a few, it was not pretty.
