1989 camaro 350, Z28, TPI.
My problem is it will run and drive as long as it's not turned off from the initial start.
When it is turned off it will not start immediately but after waiting 5
minutes it will start again and run as long as it's not turned off. My
understanding of the Anti Theft System (VATS) is that it not only causes theengine
not to crank over but it also sends a signal to the Theft Deterrent
Module (TDM) that gives a signal for the injectors to fire. If I squirt
fuel in the TPI It will start and run as long as I keep this up. So I know
it is not getting fuel. I assume the pump is doing its job as it checks out
fine 40 psi. Replaced the module in the distributor and the same results.
Something is not giving the TDM or the CPU the signal it needs to start it a
second time after initial starting. I hope this describes my problem so you
can get a better idea of what is going on.
