I made a mistake on that ...the cam is connected to the opti distributor that is how it controls the engine firing.

In 1996 the cranksensor was added ...

I would have him look at the coil and ICM for being defective ..if that is bad you will get no spark....

pcm is the computer. this can also be defective causing a no start / engine run condition.

sometimes bad grounds or a error in hooking up jumper cables can damage the pcm/computer ..

What does "ICM" stand for.... Ignition coil _____? maybe...if that's ignition coil module, we've already replaced that, and the the ignition control module as well.

the ICM is the ignition control module. this can be tested. autozone stores usually have this wells tester to do this , that way your not guessing if defective.

wells makes this tester only for autozone............

i already stated that we put a brand new in....does auto zone test it on the car or by itself?

[maxwedge]

Out of the car.

I would take the old ICM and new ICM to autozone and have these components tested.

like a starter / alternator these are removed then put on a bench
tester. test old and new.

who is the manufacturer of the opti distributor ?

what is the part number of the replacement distributor?

who made the distributor cap ? also the rotor ?

If the opti distributor is bad you will get no spark . If installed wrong etc.

All the b-bodies got the later vented opti so the early comments on asking if your car was "updated" just show the ignorance of the poster.

With an incompetent mechanic such as you have this is going to be very hard for us to help with. Everyone likes to freak out about how "loose" the LT1 timing chain is but reality is nobody ever has an actual problem with it I have used it with cams with a full 30% more lift than stock turning 1300rpm more than stock without issue.

Have you tried giving it a little throttle while cranking? One time I had an idle air control valve died closed and the car would not start or idle without some pedal.

I know you said there is no spark but with the incompetence the mechanic has exhibited already I am not inclined to trust much of what he says.

I talked to another mechanic and he aid that since i change all of what i changed, the car should start. he told to get this company out called "pop a lock" and that they will be able to reprogram my car key. he said that more then likely the car lost it memory for the chip in the key. he said that's why i never get a spark...

my 96 impala has a resistor in the key. it is a two sided metal piece built into the key. the resistor may have fallen out. or the ignition lock may be worn /dirty so that it cannot sense and compare the key resistance to the programmed value.

when this occurs the dash should indicate this..

when you attempt to start the vehicle with this all occuring with the issues above the engine will crank but no fuel pump or igntion spark to the plugs will occur. this will not just prevent spark but also the fuel pump will also be disabled.

The key has NOTHING to do with spark....since I think the start system uses a starter enable relay, the fact it cranks means the key is ok...

I was in error on the starter operating with a bad key/ignition cylinder.

the wrong or defective key will cause the theft deterrent module to not enable the starter, and the fuel pump.

the theft deterrent module will throw a security light on if the key is defective.

the theft deterrent relay prevents or allows the engine to crank.

since the engine is not cranking no spark ...

well thats how it is on the 1996 ...

Sometimes when that issue occurred I would get a "key Fault" light and nothing would happen. that's not the case here. it is a least trying to start
