Car won't start
 

My VE makes a moaning/scraping noise everytime i try to start it up(it wont start) with the clutch pedal engaged. After about a week of trying to start it with no luck, i went to start it one morning and the clutch pedal sunk to the floor(same high pitched moan/scraping) I changed the slave cylinder and bled the system but the problem persists...HELP i dont know whats goin on. ive searched and im wondering if i have a bad throw out bearing.

I have a 1989 nissan maxima. It sat for 7 years, since ive had it i put on, new spark plugs, spark plug wires, K&N filter, Camshaft position sensor/Distributer, clutch, water pump, rear main seal, timing belt, tires, interior work, and exhaust. nothing major, just regular fix ups. When i got it after sitting, it appeared only the spark plug wires were chewed on by mice. Im having a very big problem with it tho. It starts fine, and the computer tells me code #55, meaning nothings wrong. When i drove it it missed and spit and had very little power, but sounded nice under 2000RPM. So i looked at it, I found out my injector was spraying in way to much fuel, i could smell it and that cylinder, plus 2 others were not firing. all 3 back cylinders run fine, but none of the front run at all. the far left front cylinder, i think #2, Was spraying way to much fuel, so i replaced the computer, later to find out it dident fix it, and plus my other 2 front cylinders, i think #s 4 and 6, werent getting enough fuel. i tested them, the far left front injector plug read like 13v, the other 2 read around 2.57v. all 3 back ones read between 11 and 12v. but the front 3 stay the same they dont change ever, to open and close. im getting spark, air, and fuel, i checked, throttle position sensor, grounds, emission control sensor, plugs, compression, intake, and they all turned out good. Ive seen on forums people have this same probllem, ive been trying to figure this out for a few months now, could you please help me or just tell me what i could do or need to do to fix this? Thank you very much, Robert Zeromski.

Pull the camshaft position sensor off the engine but leave its connector connected to the harness. Turn the key to ON and then listen for injectors clicking while turning CPS shaft by hand. With engine not running you should be able to identify which one(s) are not working.

i allready know what ones are not working. all of the front 3 cylinders.

replace an injector see if that helps. check wiring really good for cross connections, clean and add an extra ground for a better start. download your esm an troubleshoot

Tests you performed were indirect. I thought you wanted confirmation before replacing injectors otherwise what was you were asking?

no i alllready tried replacing the injectors. thats not it. i want to know why they are getting power and opening constently. Thos front 3 cylinders wont run.

If you're sure the front 3 injectors are ON all the time (have 12V between their contacts) then the only thing is the ECU unless of course you connected front injector harness to a wrong socket. I'd simply disconnect ECU and repeat the measurements. This would allow you to see if the ECU is driving those injectors to the ground.

i can turn the key on with my computer unhooked?

yes
