1994 Nissan 300ZX Q&A
1994 Nissan 300ZX Question: Extended Crank
I have a 1994 300zx non-turbo. Over the last 6 weeks, the vehicle has had an extended crank, when the engine is cold. I have tried some basic repair myself, but have been unsuccessful thus far. I have changed the fuel filter, spark plugs, battery, and the fuel pressure regulator. I recently read the codes that the ECU has and it 32 and 34, which is a knock sensor or a EGR valve/solenoid. Any ideas or thoughts would be greatly appreciated. - jmhollma
These problems are very hard to fix, I've even seen it caused from the type of fuel used. Did you find out what was causing it in your vehicle? - highexposure
i had a similar problem on my 1990 300zx, i had just replced the cambelt ,tensioner, idlers and water pump, i reassembled it and it took a long while to start from cold, it never had this problem previously. i discovered the temp sender connection near the themostat housing was loose, after carefully fixing the problem it started immediatly and has done so ever since. - Visitor
