car shut off pulling out of my drive way pushed it back to the guarge and ran for codes it had a bad crank sensor code replaced sensor with a used one i had in the guarge didnt starts put on a new one from napa still wont start and i cleared the codes on the computor the fuel pump primes up and ideas itwas a new opti when i just rebuikt the motor

 

Stick or Auto?? If its a stick check the Safty switch under the dash. The Big black box.

 

it turns over but wont start new crank sensor new icm new coil im lost

 

The crank sensor won't keep it from starting.... its only there for misfire detection.

Why not provide detailed info on your car, using the "signature" feature - year, model, engine, trans and any major mods. That way, people won't have to ask questions about the car before they can help you. When someone does ask a question, its generally a good idea to respond so they can help you. Is it a manual or auto trans?

Post the specific codes you are getting.

When you replaced the Opti, did you loc-tight the rotor screws before installing it? Do you have spark? Have you checked the fuel pressure?

 

its a 6 speed with stock 30000 mile bottom end ported and polish intake and head 52 mm throttle body 30 # injectors long tube headers cat back under drive pulleys electric water pump new gm opti (didnt loctight screw ) cc 503 cam 1.6 roller rckers computer need to be tuned for change in exhuast and no rear o2 sensor

my buddy cleared the codes before i seen them he said o2 sensor codes and crank sensor

 

Do you have spark? Have you checked the fuel pressure?

 

no spark at coil has fuel

 

i have no spark at the coil or at the plugs and on the icm plug i have 12 volts on terminals a and d but on terminal b i have zero volts

 

When you say you have fuel, are the injectors pulsing when you try and start it, or do you just mean you have fuel pressure when the pump primes?

 

how do i check injector pulse i know the fuel pump primes and i can smell fuel when i crank it over and the pink wire on the injectors has 12 volts

 

The pink wire always has 12V when the key is in the "on" position. The PCM supplies a ground to fire the injector.

You can check for the injectors getting a ground with a "noid" light, a cheap device that plugs in between the harness and injector and flashes when the injector get the ground to fire.

Have you rechecked it for codes? The code for the low resolution pulse from the Opti will shut down the fuel system. You'll get a few pulses of the injectors when you try and start it, but after the engine turns two rev's with no low res pulse detected, the PCM shuts down the pump and injectors. But if you don't have the code, its not the optical cam position sensor in the Opti.

You might want to add a "signature" with basic info about your car... year, model, engine, trans and any major mods. That provides people with the info they may need to help you. Not all years are the same in all respects.

 

found out whats wrong with the car look at these pics WONDERFULL OPTI
