my car is not my daily driver. I crank it and run it about twice a week. When I go to crank it after it has sat more than 2 days it is really hard to crank. The battery is fine. The motor turns over but doesn't want to fire up until about 4-5 tries. I let it turn over several revolutions each time. after 4-5 tries it will fire but not fire right up. It tries to stall a few seconds, then comes to life. It has 120k on it, open exaust, 52mm tb, PP heads, relocated IATsensor, TB bypass. I guess new plugs/wires wouldnt hurt. Is my coil weak ya think? Should I have gas-shroeder valve checked? what else do you guys have coming to mind on this?? Thanks!!

 

I would check for a leaky injector or a weak fuel pump. If both of those check out alright, then I would start on the ignition.

 

Check your fuel pressure and see if its in spec.
