Hey Greg,
Just went through all the same BS with mine.

It's only running for a second because the VATS is shutting down the injectors.

bakerelectronix@verison.net has a by-pass module

If your truck has Vats you can put a resistor in.I got one from Bandit,but had to go with the module '82 El Camino.Took about 10 minutes to install.

Baker electronics seems to have it together,answered my e-mails immediatly.

Not like someone else
