hi guys ,

I'm looking at my friends GTP and it will not star

Resent tune-up done 2 months ago , he was getti issues 2 weeks ago it not wanting to start but waiting about an hour it would start like as if nothing wrong at all :
When it would start ran good ?

Ok can anyone suggest what I can look at first? Like crank sensor or ignition mod

I will check for spark first

Thanks
