[M30ddeci]

I have a 91 M30 that has a hard start when engine is warm, sometines 5-8 seconds of cranking. Replaced plugs and started great for 2 months now having same issues. Any history on this issue with M30. Once running it runs great!!!

have u pulled a plug to see if there fouled again?? can tell alot bout an engine by the plug signs. is there a engine light on?? do u have good fuel pressure?? there are several things that can cause that prob. mine started to miss fire on cuple cyldrs so im doing an engine swap. rather drastic swap tho a 300zxTT engine, more for fun . anyway. compresion/ fuel/ spark the three ingredients to any running engine. ur engine isnt running very good so look for which of these is missing. good luck
