about 2 weeks ago i played in my turb , no big deal added a boost controler (manual) when i started the car , i gave it 2 LITTLE pull on the throttle cable , when the car just recv up like crazy T-BODY CLOSED! the cable went nback to normal as in the t-body was CLOSED! any how... i changed my oil , i overfilled it about ,5 litters , no big deal , but sudentlyu it started bucking , not fireing corectly , thats cause i had iridium spark plugs , so i change them , and all of a sudent , car wont start no more , i flooded the car SO BADLY , i had 2 litters over in the oil pan , so i change the oil . again , oil smeled like gas BIG TIME! , so i put in some new mobile 1 new car oil 5-30w , syntec , catr wont start any less . no fire on my spark plugs , then , sundently i press on the clutch , and is starts , as in car was cracking fine everything but it STARTED when i pressed the clutch , my clutch is by passed...for the starter , but the weirdest thing it that , my ignition dosent shuts off imediatly , when i close the switch it takes about 2 seconds before it shuts off...

but that the least of my problemes.... now the car RANDOMLY cuts , not as in the gas dosent reaches , cause my pump make a SICK SOUND! diiiiii!!! as in if shes having BIG time trouble feeding the car with gas , ps its a walbro 255lph , my gas filter is brand new 1 week old300zx fram filter, any how , the car smels gas about 2 block away , its sick , i tried hitting about everywhere the wiring , incase it would be a bad conection , something , and also my speed gauge freaks , some times im going like 100 and it goes nuts and cranks up to 180.. then slowly goes back to 50 then 100 then 140 and so on...and on idles im going 20 and if i rev up im going up until 60

i thoght of taking it to nissan dealert but i ony mentioned silvia japan motor in a canadian 240sx... then said. f"ck that!


i know i had a similar probleme with my other nissan 240sx with ka24e motor , it cutted radomly...! it was the gas pump too and the maf , but what's weird is that when the car cuts , the speed and rpm gauge drops to 0 , as if it ... died , as if i would have shut the key off of cutted the ignition wire!

i know my message is long and boring but i neeed help! , i tried everything , lie i said before i aint no dummy i have a degree in electronics , and i work in cars , but im just outa ideal , and also , is the ka24e maf the same as the sr20det maf? plug matches , same number i think? ,

my fuel pump stoped working so i changed it , my fuel filter is brand new i just change it 5 minuts ago , i dont seem to be lacking gas , the motor seams to be stoping either cause the crank sensor stop sending pulses , or the ignition is turned off , but i by passed my ignition with a jumper to a 12v source but it still dies? , any body has ANY ideal!
