HowlerMonkey Posted October 10, 2009 Share Posted October 10, 2009 I need one for my M30 with L28et and am having a hard time finding it on the 1985 300zx I have chosen to source it from at the junkyard. Any ideas before I just wade in, remove all the interior panels, and start searching? I'm sure it's near either side kick panel and either above said panels or sunk into the "A pillar" behind other components but it is just too hot here to spend time doing an extended search by unbolting tons of most likely rusted bolts/screws.

HowlerMonkey Posted October 10, 2009 Author Share Posted October 10, 2009 Never mind......I found it in the FSM. Strangely, text search did not find it in acrobat reader. For the record, it is located in the "B pillar" on the driver's side.......unless the drawing is reversed. Of course, this is the area that gets wet (do you have wet seatbelts?) when the rear side windows become unbonded to the body so... If you wonder why it didn't come in 1987 and later nissans, it is because they went to dual feed injector scheme where the fuel return system allows fuel to flow in one feed and out the other to cool the injectors after a hot soak. Nissan figured out the fuel system modification was far less expensive than the supplemental motor/timer/wiring system and the extra burden on batteries that running a blower 15 minutes after most every run cycle in warm weather causes.

FlatBlack Posted October 10, 2009 Share Posted October 10, 2009 If you wonder why it didn't come in 1987 and later nissans... I thought the 86s came with the 'top and side' feed injectors as well? I could be wrong though, please correct me if I'm wrong. Just like the 74 Zs, the 86 300ZX was a bastard year from what I've read. Quote Link to comment Share on other sites More sharing options...

FlatBlack Posted October 10, 2009 Share Posted October 10, 2009 So... I'm half right? [My DD is a 86 Turbo Z31] Quote Link to comment Share on other sites More sharing options...
HowlerMonkey Posted October 16, 2009 Author Share Posted October 16, 2009 Cooling fan on the L28et in the M30 made all the difference. It no longer vapor locks. Quote Link to comment Share on other sites More sharing options...
HowlerMonkey Posted November 2, 2009 Author Share Posted November 2, 2009 I have been using one from a Z31 but had trouble with it because the Z31 manual just copies the section from the 280zx manual.......which was not correct even in the 280zx manual. I used the schematic supplied in the 280zx manual and followed the board traces through the components to determine the correct pin out and now it works. Luckily, the manual being wrong caused no smoke when connecting it that way........It just did nothing. It works correctly with the wiring on the right side of the diagram. The Z31 cooling fan on the non-turbo itself is the same as the one on the 280zx but uses different brackets and ducting. Not sure if the turbo one is the same since the non-turbo one I used sits where the alternator usually is on the turbo version. Quote Link to comment Share on other sites More sharing options...
