I have a infiniti I30t that won't start. It would not crank yesterday morning tried jumping car with no luck. Pulled battery put on charger. Had battery tested. Tested good. Still car turned on but did not crank. Pulled starter had it tested. Tested good first two times but did fail third time. Put new starter in and changer spark plugs because 2yrs old. Turned over but didn't start. Smelled fuel. Pulled plugs saw fuel on plugs. Tested one spark plug by grounding and cranked engine over had blue spark. Decieded to pull and replace fuel pump. Still cranks but doesn't start real strong smell of fuel? Any other clues? Prior to it not starting was having a problem starting car like needing to give it gas to start it (thats why changed fuel pump and filter). Help?

If you have a good hot blue spark, either you are getting too much fuel or the timing has jumped which usually result in back firing at least. Have you checked the fuel pump pressure? You may have a bad fuel pressure regulator and it's dumping fuel.

Let me know.

I put old plugs in and was able to start car first try. The new plugs must have been really fouled bad. I returned the new plugs and put new set in car fires up first try. Couldn't check fuel pressure, couldn't find a valve to plug into.

Thanks Joe.

It sounds like they fouled. If it is running good, let the old ones in. If you replace them, make sure the new ones are properly gapped.

Let me know if you have other questions.
