It sounds like a security system issue. The only solution is to contact a dealership for help with the code. It involves the on board computer system and has to be hooked up the the scanner at the dealership.

Fuel pumps? Filter? Fuel injectors? Main engine wiring harness? Coils? Wires? EZL?

You say you replaced parts but you didnt say which ones.

Check ASR system. Wheel sensors would be a good start because thats what the system checks for speed difference at the wheels. It reduces power to keep you straight on the road.

Lots of things to check. From 1993-1995 the US made car compaies use biodegradable insulation on it wire which ages with engine heat and then shorts so check that first. It has an upper harness for engine and lower for charging and starter. Then a real tune up is next coils, cap, rotor and wires. Once youve done that fuel system is next on the list fuel filter and fuel pressure.

it's the brake switch, behind the brake pedale located, to replace.

The 2 things to help start at first try are the coolant sensor and the cold start valve. If the coolant sensor is bad , it give an erratic resistance so the cold start valve could not open to assist the start. If the cold start is not open then you have not had the assist from the cold start valve. Good luck.
