97 Cadillac mystery, Car will start hard and starting is hit or miss. Sometimes will start easy like a kitten sometimes you have to press the accelerator to get it too start. RPM side of the dash remains at zero. Code say ignition Systems,

What is your question?

Had the car a little over a year. Crankshaft sensors have been replaced, fuel filter been replaced. Unrelated to my starting the Power of steering pump been replaced. Codes say ignition systems , nothing specific. RPM side of the dash remains at zero even when driving at 30 mph. Service engine light is on and no fuses broken. Mechanic says it sounds like a computer problem based on reading forms like this. But I want to double check. Starting is hit or miss sometimes take ages or instant. Never has overheated on me, all fluids are I where they need to be. AFTER much work and checking everywhere on the car STILL STARTS CRAPPT haven’t tested the starter yet but that’s tmrrw. Battery voltage is good, fuel pressure is good, and no leaks.

What makes this problem better or worse?

When sits for any time not running.
