Angry Recently swapped a head/gaskets and now camaro turns over but no fire

I recently blew a head gakset and replaced my intake gaskets and head gasket.
so i had to swap a head because other was cracked before all of this the car would turn on fine it didnt stall to turn on i turned the key and in the same second it turned on fast and healthy....
Now after i hooked up everything it like it is out of gas i remember when i ran out of gas and tried to start it, it would soudn exactly like it did today when i tried to start it i feel air comming out of the exhaust and when i turn it over i can smell some gas.i pumped the gas pedal and turned it over but no start also.
im stumped.....
i have no idea also idk it the throttle cable is hooked up right or not.
ALSO this thign is really bugging me in the picture i cant find out where it goes to bolt onto and where the little line fits onto.Name:  idkwtfthisis.jpg

its a 3.8 v6
It sounds like a healthy turn over but it doesnt catch fire?
I put the new spark plugs in the head myself and tightened them as tight as i could with my hand. should i use a socket to tighten more?

Re: Recently swapped a head/gaskets and now camaro turns over but no fire

also somhow my oil pressure sensor got knowcked off or somthign and the oil pressure sensor isnt plugged in...
So my gauge light is on and the fuel pressure goes all the way up.. Idk if that matters
Also there is a sensor i cant seem to find a plug for next to the fuel rail. and here is the picture Name:  sensor1.jpg

Re: Recently swapped a head/gaskets and now camaro turns over but no fire

Some guy said he would trade late 90s prelude for it but i really want the camaro... i asked him what he thinks the problem is but he says he doesnt know it must be somthing that is at the back of my tongue...

Re: Recently swapped a head/gaskets and now camaro turns over but no fire

Your thread on the V6 Tech forum shows multiple harness connectors you haven't been able to reconnect. How many connectors and other devices do you have that are unconnected at this point? Did you hook up some of the ones you have asked about?

Looking at my Chiltons, with diagrams of the passenger side and the driver's side of the engine:

Passenger side:
-Idle air control valve on side of throttle body/intake manifold
-MAF sensor, on top of throttle body
-Engine coolant temp sensor under throttle body
-Throttle position sensor on side of throttle body
-Cam position sensor above/to side of crank pulley
-Bank 2 O2 sensor at back of exhaust manifold, just above flange
-MAP sensor on side of intake manifold plenum, at the back
-manifold vacuum source, coming off MAP sensor
-EVAP purge valve on bracket on side of intake manifold

Driver's side:
-Fuel pressure regulator on side of intake manifold plenum, toward back
-Bank 1 O2 sensor out of sight behind the exhaust manifold base, in the back
-Engine oil level switch in side of oil pan
-Crank position sensor behind power steering pulley
-EGR valve in front of valve cover

The inlet air temp sensor plugs into the back of the airbox.

Re: Recently swapped a head/gaskets and now camaro turns over but no fire

Cam posistion sensor
MAP sensor
Crank Position sensor
These three i have had problem with locating or making sure they are in which i doubt they are.
Could these cause the car to turn over but no start?

Re: Recently swapped a head/gaskets and now camaro turns over but no fire

the cam sensor and the crank sensor WILL effect the car starting. the crank and cam sensor tell the engine when to fire the spark plugs. As far as the v6 goes, i will have do do a little research in order to help you better. the plug in the bottom MIGHT be you crank sensor.

Re: Recently swapped a head/gaskets and now camaro turns over but no fire

the TPS is on the throttle body itself. that should be no problem to find.
and it looks hooked up by your last pic

Re: Recently swapped a head/gaskets and now camaro turns over but no fire

So i Noticed I done test There IS gas in the head i took out spark plug and smelled gas on tip i test plug there is no spark when i turn over the engine so im guess i have a unplugged sensor, crank or cam i know for sure the sensor with the purple ring is unplugged that i see other then that the baby blue one is the oil sensor.
There is no spark.
New plugs/wires so idk what do you think?

Re: Recently swapped a head/gaskets and now camaro turns over but no fire

if i could get a more detailed cam and crank sensor location thiswill rule out sensors....
Although I done research and it said cam and crank is th emain ignition so there is my rotten egg. Anyone got a bit of info?

Re: Recently swapped a head/gaskets and now camaro turns over but no fire

crank sensor is hooked up from front of vehicle its on the left side of crank pulley in visible sight.
Now i need to know where the cam sensor is
