95 camaro z28 LT1.
So i went ahead and did the LTCC coil conversion to my LT1.
It ran fine for 3 days. While being a friends house i decide to go home.
So i hop on my ride and turn the key and car doesnt start.
So i give it another try and it starts right up. After 30 seconds of driving it.
It simply just dies on me and doesnt start up again.
So i scan it for codes and get the error code 16 and 36. opti right
the LTCC kit is grounded fine and i has a 20 amp fuse for the ignition.
The car sometimes starts fine on the 1st try and runs for 30 minutes on idle.
i turn it off and doesnt start or sometimes does start.

the error codes appear and disappear when car starts if it wants to.
before i got the LTCC kit installed. i had installed a new delphi opti with the stock ignition not the LTCC kit. that opti failed and got a error code 16. returned it. i had a chandler opti and returned it for warranty also.

installed a new chandler opti and walla no more starting issues.
those 3 days i drove it. it had the new chandler opti with the LTCC Kit.
the kit doesnt require a ICM or Ignition Coil.

I also bought a new GM performance opti from summit since it was on deal for $200. i have it set aside for when i need it.

This situation is weird. for the past 3 years or so i have had to replace the opti. every 6 months or less. this last opti has only lasted 3 days. okay ?

this is making me think there is a shortage or the ECM is messed up.

Any tips are welcome.

so i had 30 minutes to check the car.
i noticed i was getting the low coolant light for the low coolant sensor.
sensor is brand spanking new. So i checked for leaks and found the radiator plug on the bottom was leaking. Refilled the radiator with water for testing.
no more leak and low coolant level sensor goes away in gauge.

im not sure but does the LTCC module detect that if the car is low on coolant and gets the lowlevel coolant in gauge. Can that cause the car to have hard starts? or just tell the PCM not to start the engine?

this whole situation points to the only issue being you are incompetent with a wrench. You need to figure out what you are doing wrong.

I think you are failing to catch wiring issues, like maybe the opti harness has spread pins.

the opti harness is brand spanking new. not even 2 weeks old and receiving proper voltage.
i have tested it with the key on. like stated in shbox.com.

i think if you are either going to comment on a post to help others out or dont post at all. you are just wasting your time. i have had my car for more then 12 yrs and have gained alot of experience from others on this forum. something so hard is sometimes easily fixed and is under your nose until you look at it and think it over once or twice. nobody is perfect. even a technician with 25 yrs of experience can screw up and not catch the faults. you learn as you go.

....... anyways. back to the important stuff.

i will take the opti apart and see if the rotor might of gotten loose and if so, i will just simply cut both plastic ends that touch the cap terminals that send signal to the spark plug wires. hopefully that will make an improvement.

thanks for everyone looking at my issue and making good comments.
