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.

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.

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
