I am about to order some parts for my car. I am ordering a new crank position sensor since the wiring sheath on mine is mainly gone. I am also ordering a new fuel pump relay and fuel injection relay (aka radio suppression relay) since I was reading in the fact they are the most common things to keep the car from starting. I drive my car 200km a day do all I can to always make sure it starts and runs.

I am a bit confused about the radio suppression ready. I have been reading through the FAQS. Is there a separate fuel injection relay from the noise suppression relay?

I have a 1991 940 16v and I have two identical relays behind the coolant bottle and one similarly sized relay on the drivers side shock tower behind the power steering reservoir. There is no relay at all behind the front drivers headlight. Which is which?

I was trying to disconnect the relays one at a time until the car wouldn't start to see which one is the radio noise aka fuel injection relay, but the electrical connector is REALY on there, so I didn't want to force it and break anything.
