Please refer to the above website for assistance with this problem.

ONly sign I would use is if it gives a mileage in the maintenance portion of your owners manual. Most times it is timing belts that need replaced at 80K miles or whatever but that isn't necessarily the case with timing chains.

No other real sign on when to change them other than when the fail and when that happens you jump from replacing the belt/chain to replacing the engine.

Good luck

Salvage yard or dealer. Places here in the USA, I send mine to be fixed. I fix IP's. But don't mess with mileage and certain chips.

look in the engine bay against the firewall to the right under below air filter box to throttle pipe usually cylindrical shape made of metal silver or black in colour

Here's a link showing you. Where is the crankshaft position sensor on 2004 suzuki forenza located

Did you check the distributor cap + rotor arm, points, leads, coil?

The malfunction indicator is not lighting up initially.
