What causes a Chevy Corvette 86 TPI to stall?
It never stays constant. Its stalling under a minute after start up, and it will stall once the idle drops if I rev it while its in P. Also stalls sometimes when shifting into gear (from R to D). I tried changing out the fuel pump with a new one, but then it would not start.
Can a bad air control valve cause an engine to stall?
Sometimes the engine stalling will happen on its own while other times, increasing the load on the engine will cause it to stall. For example, if you turn on your heater or air conditioner when you have a bad idle air control valve, then your engine will probably stall immediately afterward.
Can a low pressure fuel system cause spark plugs to wear out?
A low-pressure fuel system will destroy the spark plugs that ignite the fuel in an engine’s cylinder. If by chance you are replacing them and you find they are worn out before their time, you might be looking at a problem with your fuel system.
Why does my car stall when I Turn Off the engine?
If your car’s engine stalls while running or at idle, it is a clear sign you are having some problems with your fuel pressure. This may be due to fluctuations and sudden drops of the fuel pressure. Today’s electronic cars have a fuel pressure sensor that intelligently calculates if anything is going wrong with the fuel pressure.
How does a fuel injector cause an engine to misfire?

A low-pressure fuel system will destroy the spark plugs that ignite the fuel in an engine’s cylinder. If by chance you are replacing them and you find they are worn out before their time, you might be looking at a problem with your fuel system.
Where do the injectors get their pulses from?
I borrowed a set of Noid lights at Autozone. They proved that there is no pulse going to any of the injectors. The injectors, or pulses to them, are definitely the problem. Do the injectors get their pulses from the module inside the distributor, or the ECM, or both?
Is there a fuse for all 4 injectors?
The schematic shows each set of 4 injectors has its own fuse as a power source with the key in the RUN position so I would verify that voltage is present at the injector plugs. The odds of both fuses being blown may be slim but it should not be ruled out.
