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.

You have a loose connection probably at the alternator that's usually the issue. You might have to trace the wire it runs to the DME.

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.

Possible switch gear unit has malfunction. Need to get it scanned to fully check this out. Don't just replace parts on a guess.... Very expensive and will cause issues when you take it to a professional

Pull the out and test to make sure they are getting power.

The lift arms need replacing.

Press the Up/Down buttons on the steering wheel until Settings is displayed on the instrument panel, then press the OK button. If you need more help email me at [email protected]

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.
