SO i posted about cylinder 1 not firing a couple of days ago i narrowed that down to the fuel injector, tested for spark and i did the age old screwdriver test on the injector and to my amazement it actually was firing but it could be clogged or weak so i decided to change it. here is the list of things i did while i was under the hood of my car:

replaced injector #1
replaced ALL under hood rubber fuel lines
new fuel pressure regulator
new fuel filter(300zx filter)
new spark plugs
new knock sensor
New plenum gasket
added grounds(had bad grounds)
cleaned the TB
cleaned gunk off IM.

So great everything has been replaced i go to fire up the car and nothing. not even a cough. I have tried spraying starting fluid, clutch kicking the car will not start. I checked for spark and i did not see my plugs fire(its not the most sophisticated ways because i dont have a second set of eyes to help me), now what gets me is i touched nothing ignition related except for spark plugs. So for the plugs not to fire is confusing to me.

The other thing i was thinking it was, those pesky side feed injectors are a b1tch to install, i noticed that around cylinder 1 wet and there is a strong fuel odor, is it leaking to the point there is not enough fuel for the car to operate? And even it it was wouldn't i get a couple of coughs out of the car, some hope atleast? I found a local wrecked car that i will just pull its fuel rail with injectors off of and forget about trying to seat those things correctly. But i need to know would that be the case?

 

check the immobilizer that will not let the car turn over or even inject the fuel. How about any codes,did you connect everything back together properly.

 

Its a 95 btw doesnt have an immbolizer

 

compression test sure engine is not dead.

 

Any codes? Maybe check the crankshaft sensors for the no spark issue. And check the grounds that hook onto the lower intake manifold. And 99s is when they implemented immobilizers.

 

if it's not even turning over there is something electrical not giving a good connection or something wrong with the starter. where were your grounding issues? check wiring to starter/solenoid and corresponding grounds if you haven't already.

 

Motor is definitely not dead. That much im sure of.

i replaced those sensors so they are good. And i did double check those grounds. They are on their good.

 

No its turning over, its cranking but it will not start.

 

You put the fuel filter on the right way?

 

Im pretty sure i did one side said in the other side said out and thats what i did.

 

ok, it's a 95 never mind the immobilizer, check the Gaskets,vaccum hoses,FPR,fuel filter, injectors, one thing that's off it will cause a disaster. Wire harness check and connect all if not so, check the manifold and lining up and bolting same with the TB. The coilpack and the harness.

 

ckpos,there are two sensors. voltage check them than the sensors it self GL.

 

all the position sensors ok?

 

camsensor too man. make sure thats pluged in and working

 

check and make sure air hoses are properly connected too.

 

Does the cel come on when the key is just in the on position? (Engine not running)

yea it does.

im not looking foward to doing that but i might have too.

 

Did you ground your injectors? I know that normally gets unscrewed when you pull a rail, and if you did not hook the injector grounds back up, it would crank but not start....just throwing it out there.

 

yes thats the first thing i checked. As soon as i find my gawddamn multimeter i can start checking voltages, continuity and resistance.





.....I bought a good multimeter too it cost me $50 at radio shack.

 

But what im thinking is what kev said with the broken wire somewhere or its just that injector causing pressure issues.
