ok ,so i have an 1990 240sx manual with stock ecu so i by passed all of my fuse boxes , but i have fire on my spark plugs , and gas coming out of my injectors , why dosent it starts , not even a pow , nothing! here what i did so far...


removed the valve cover , looked for top dead center piston 1 , when it was on top , both valves closed , fire was on that piston .

removed completely the fuel regulator to enable all psi of gas to flow freely , so no jamed up fuel regualtor , 300zx BRAND new gas filter , jegs with plenty of pressure gas pump (when i removed one of the gas lines it squirted EVERYWHERE...) and i removed my injector line , to see if gas was squirting out of the injectors , gas was spraying ....

i unpluged one of my spark plug placed an other spark plug at the end , and fire there was...

i removed all spark plugs to let the block dry out , incase the was any exces of gas(drowned) for about 30 min it dried out....

i had a slight probleme with one of my ecu .... my original ecu has a light probleme , the 2 leds the red one is constently on , and the green flashes only once , before i had that probleme it gave me 41 error 41??? , but when i pluged in my 89 240sx manual ecu
and it gave me 55 , as in nothing is wrong .


my cranck sensor is clean , i opened it , it looks very clean ... no oil in the laser operated cranck sensor... the tiny holes a fine...


is there ANY profesional who knows what colors are on the wires that i need to plug on a 12v? , do i need to place a 80ohm resistor on each of the output for a relay?


im just simply out of fu**ng ideal!!! , i allready had a probleme like that , it was my timing , now my timing is good , i tried all otehr position , top , lower , center piston one , each of the 4 holes to put a spark plug wires i tried the piston 1 wire.... nothing starts!! , not even a single little noise rom the engine.!


im about to simply push the car down a cliff and compression start it! as i doubt it'll do **** ,

so tell me , wtf is wring with my car! , it just dosent starts... ive got fire , ive got gas , ive got good timing??? so wtf...

please help , im SIMPLY OUT OF IDEAL!!

 

maan i glad im not the only one having the same trouble

 

i ben at this **** for a week straight some one help us out ppllleeeeeeezzzzzeeeeeeee

 

When you turn the key does it click or anything?
Try tapping your starter while someone turns the key and see if you hear anything or if it starts.

 

did it start before you bypassed the fuse box?

 

i jus got a new starter

 

I FOUND IT!!! THE FU****G GAS REGULATOR!!!!


there wasent enough gas spitting out of the injectors...!!!

try removing on of the spark plugs , trow in a LOT of gas.. i filed up an dish saop bottle of gas and threww some in the piston chamber..

then start again if it backs fire , pow ANYTHING involving a fire...


BINGO!!! REGUALTOR BAD!| , even if some gas is spitting out of injectors , dosent means theres enough....

IM SO FU**ING GLAD ITS ALL OVER

 

imma check mine..i hope i have the same luck

 

looked it up in the fsm. 43 psi at idle, 34 psi at 2 grand

 

dble post

 

did u jus put a new one in and it cured it

 

no lol.. i missed pluged the hoses , the INPUT is the one taht goes stright to the fuel line! , and the feedback line is the one that has the regulator at the end of the fuel line , big mistake from me! and yes i only removed the regulator placed a new one and everything was good , but try my trick , drop a lot of gas in the chamber , and start....

 

maaan i got fuel in mine..i took da damn spark plug out and saw a lil pool..imm sooo pissed tryin 2 get dis **** runnin

 

sure you got fire and PLEASE CHECK YOUR TIMING"!!!!!!

 

got my ***** runnin..YEA.im souped..skippin and the whole nine...!but now i got smoke comin from the headers.it never done that before..could it be from the lil bit of gas that was mixed in with the oil starting to burn off?what do u guys think???
