Exclamation Sometimes it starts, sometimes not


Not sure to be on the right section of this Forum, let me know if not

I have since Friday a weird problem.

Friday morning, my car starts as usual. At the lunch time, it just didn't.
Everything looks right, but when I was turning completely the key, the car won't start at all, exactly as if I didn't put my foot on the clutch pedal.

Friday evening it starts, saturnday not, today it starts, half an hour after that I tried again and it didn't...

I have no clue on what is going on, I don't even understand the problem...

Any of you has a hin/clue/suggestion?

Thanks for your help!

PS: My car is a 04' convertible 2.4 atmo manual transmission

When in the no start condition do you hear the fuel pump priming the system?
Is the engine cranking over and not firing or no crank at all?

Sometimes the contacts for the starting relay can work themselves loose. remove the fuse/relay box, push and squish on that relay and see if it makes a difference.

My first PT had random no cranks but would start only with jumper hooked to starter. Replaced the battery cables and 4 years later I never had a single issue. Well except when the auto shut down relay would intermittently fail causing the car to not start or it would shut the the engine down while driving.

Grounding wires. If only to cross it off the list.
