im serious the ecu wrieing is differant there is a little silver box 3 boxes up from were the ecu fits the wrie plug that goes into that eletronic unit is differant. than the wioreing in my 1982

 

That's the fuel pump control module.... all 280zxt's had it. Again I say, WHICH WIRES ARE DIFFERENT? Give me the harness pin# or color code of the wires that are different between 82 & 83 turbo models.

 

ahhh the good old canada dash, hehehehe

 

nismo pick... the fuel computer wires are the same , but hears what i got

x blue+black white+yellow x

White x BLACK Blue+white

thats for the 82

hears the 83

X Blue+black - white+yellow X
?YELLOW? X Black Blue+white

is it possable that the yellow wire meens that the fuel computer is burnt out ? i took it out of the 83 and tried to plug it into mu 82 and my 82 didint want to work.. so chanches are its the fuel unit huh nismopick ?

 

Do you hear the fuel pump kick on when you try to start it? Make sure that box is grounded too... the fuel pump won't work if it's not. And the extra "yellow" wire for should be the least of your worries.

 

yes the fuel pump kicks in.. question when i turn on the 82 ecu inside my 82 280zx the green light inside the ecu stays on when i turn on the key all the way... but when i turn the key all the wya in the 83 the green light goes out ? what could be the cause of that ? p.s. im getting the car to.. back fire and the POV is chriping but no start,,

 

So the fuel pump works... which means you don't have to worry about those ecu/fuel pump module wires... and it backfires... which means it has at least a little spark. And if I remember correctly, the plugs were soaking wet in fuel?

 

If it's backfiring, it would most likely be lean.

 

how do i change out the fusable links ? make new wires? and clips ? is it really that eazy ?

 

sounds like the timing might be WAY outta whack. set the engine to TDC (on compression) and verify the position of the rotor (in the distributor). It should be pointing relatively close to the #1 tower on the cap.

 

alright i will set the compression to TDC tomorow morning i am just way to tired.. tonight to do anything.. p.s. fairladyz is there a eazy way to set it to TDC ? p.s the iggy swtich is good....

 

the easiest way to set it to TDC is to pull out all the spark plugs and line up the timing notch on the crank pully with the '0' on the timing plate. Thats TDC.

 

Okja fiarlady i pulled out all the spark plugs...turned the cam shaft to what i belve to be TDC..is that how to do it right ? send me a private messege please

 

You shouldn't be turning the camshaft... just the crankshaft (is that what ya meant to say?) The easiest way to see if the engine is at top dead center, is to pull the distrib cap off, and turn the crank to the 0 degree mark on the timing plate, and make sure the rotor under the cap is facing straight forward (if you put the cap back on, it would be directly under sparkplug wire #1. That is TDC.

 

yep thats what i ment sorry nismopick i am soo tired from going to work 8:00 in the mroning to 3:00 or today 4:30 then coming home and working from 4:50 today until 9:00 tonight.. all im doing is cleaning the car up to make it look better right now until my stuff comes in the mail.. i just want every one to know somthing " i crushed a 1981 280zxt " and i will never crush a 280zx ever again ill buying fixing eather keepem or sale them..
