| LT1 Problem! He died abruptly!
The problem, my engine dies sometimes abruptly, it dies after 1 week sometimes after 5 minutes. The LT1 (´96) installed in my Cobra Kit dies suddenly after different operation times and temperatures.
Things I checked and replaced:
- Engine ground is perfect
- Battery is o.k., voltage on system is allways 12V
- Ignition Module is replaced
- Opti is replaced
- Coil is replaced
- No codes are indicated ever
- Fuel pump runs after switching on the ignition
So, I checked the ignition wireless with an voltmeter and find following problem.
From all wires of my ignition module, I have only one brown wire witch goes direct from the ignition module to the ignition coil. I measured on this wire normal 12,8 volt! When my engine died, I measured permanent about 4 or 5 volt!!! ;-(
After 10 seconds or after 30 secons, the voltage go on 12,8 volt and I can start my engine!!!
The same on an white wire on the ignition coil. This wire is for my engine revolution I think!
Funnily enough, I have a ECM from 93 and an LT1 engine from 96!!! My ECM works with map and maf!!! Is this possible Perhaps, it´s normal in a Cobra-Kit!!!
Please Heeeeelp and sorry for my bad English!!!
Cheers from Germany
