1990 Porsche 911 Carrera - Answered Questions & Fixed issues

I suggest a locksmith. They can make a key to unlock it for you.

Check connections to ECU under pax seat I believe, possibly a failed ECU, make sure you buy a new coil as well if replacing ECU.

run the fault codes first as there are a number of reasons for no spark --the last being the coil. There is an ignition module ---position sensors --timing belt --shorts in the cap --bad coil lead to the distributor . The ignition module may be only have 7.5 volts to it from the coil in which case you may have burnt it out with the 12 volt application and you will not get any spark unless the coil is in the circuit as it is a transformer that generates the high voltage necessary for a spark at the plugs.

it is called your pcv

if the key will not TURN the ignition try spraying alittle wd40 into it ,just a quick shot then run the key in and out a few times .if it turns but won'tstart check your battery connections ,may need cleaning and tightening. if lubing ignition does not work you may need a newly cut key a twenty year old key may be worn out.see a locksmith or dealer

check the gear oil in the transmission Porsche is notorious for trans problems, and it wouldn't surprise me if it was leaking. too low a fluid and it will not go into any gear but the one that was last selected.

YEP SHIFT LINKAGE LOOSE OR WORN NEED ADJUSTMENT.ADJUST THE SHIFT LINKAGE BY POSITION THE SHIFT LEVER IN NEUTRAL .REMOVE THE REAR TUNNEL COVER IN FRONT OF THE REAR SEAT.PULL THE RUBBER DUST COVER FORWARD ON THE SHIFT ROD.LOOSEN THE CLAMP BOLT ON THE SHIFT ROD.MOVE THE TRANSMISSION SELECTOR SHAFT ALL THE ITS LEFT STOP,KEEPING IT IN NEUTRAL.WITH THE TRANSMISSION STILL IN NEUTRAL . MOVE THE GEARSHIFT ROD TO THE RIGHT TO ITS STOP.TIGHTEN THE CLAMP BOLT TO 18 FT LBS.TEST THE SHIFT LEVER PLAY SHOULD BE THE SAME IN ALL GEARS IN ALL DIRECTIONS.

hello there
most of the cabriolet in 1990 are electrical.
If you like to open manualy it is posible only if you disconnect the arms which are attached to the motors on each side .The arms and motors are located behind the side panels.Disconnect only the connection to the arms not the arms from the motors,there is an allen head bolt to be removed.Aftrer this you will still need to operate electricaly the two (on the top of the windshield ) el.motors(latches).
If you use the switch to detach the top from the windshield then you can finish the openning by hands(manualy) this is the only way it would work for you.

Let me know if you need more help

With a rarchet, extension and socket remove the bolts holding the latch to the core support and the hood will open. The cable usually just fell off. reattach or replace as needed.

that oil leak or another is dripping on to the exhaust manifold or exhaust pipe ,that is where it is coming from,,

Replace the top motors or check cables from motors to top. There are 2 motors one for each side of the top.

have ur shift linkage bushings replaced....most likely thse are torn or completely broken .. this is common on these models..also on some vw's of the same years

It should be 850 Cold Cranking Amps, 850 not 80!!
