My 1972 240Z car have a 280zx turbo engine in it w/ fuel injection & pump and No, I don't think it have a mech pump. Fuel filter still look good. and it's still doing puff the magic dragon coming out of the intake. I ask some guys and he think it could be timing issue??

It's a L28ET in a '72 240Z the engine been sitting for awhile, not sure for how long..but it's have not been rebuilt. The engine just got install a week ago and it run 3x for 5min each 2 days ago. Also it run for a good 3 min today before it shut off by itself, then the smoke from the intake happen...

the engine turn on, but does start-up right and this is how i got it hook up now... black/white --> +coil blue/white --> -coil pin on right --> coil ignitor (ecu) pin on left --> ???? can some one help me out, I still have one pin that I don't where it shoudl go to ground or 12V+ thanks xbangu

i just got my wiring some what straight up and after running about 4 min, the engine stop by itself. When try to turn back on my 240z l28et have smoke coming out from the intake and shut off when I try to start it.. I try it again, same thing happen? what going on???please help!!!!!!!

thanks for the tips, my wiring inside my car is fine. I tested by using a batt charger connected to the main line coming in located at the passenger side and it fine, no power drop or anything when key turning. But once connected to the engine compartment, it do it again. I am guessing it not having good ground. When key go to "acc", relay clicked and if it working properly when key go to "on" i should not hear any relay clicking and my fuel pump will pumped. But I did hear it clicking (no sound of fuel pump)and when check the V, it dropped to 0.5V (unstable). After disc & reconnected all the wires it work! but not stable. Sometime it work and other time not. Ahhhhhh

Yesterday my l28et swap was fine (engine running), until today when I try to started it again. Key in "off" position the voltage is good at 12V, but as soon as I turn the key to "acc" the voltage dropped to 5-6V(unstable) then to "on" it's reading 0.60V . From "off" to "acc" I could hear the relay on the passenger side clicked. Have anyone have any problem like this before... also when ohms out from ground to 12V fuse box @ "off" it read 1.5k @ "acc" 90ohms @ "on" 50ohms

Ok, I did a L28et swap on my 240Z, and i am not sure if that is how it start up. I turn the key to start and I hear the engine cranking, but won't start... and as soon as I release the key from start... it's started. Is that how it suppose to work on the L28et???? or I am missing a few wiring??
