You have one of the aftermarket switches? If so it's the same old issue with the resistor. If it's a factory switch, you may need to replace it. Here's the thing...and I learned this the hard (read expensive) way. There is one pin on the computer that is listed as no connection. In reality, it's a low voltage signal from the ign. switch. If it doesn't see the correct voltage, it won't ground the fuel pump to turn it on...The thunder switch that most people replaced the OEM switch with doesn't have this resistor, so you have to add it in. The wiring harness that comes with the thunder switch has the resistor in it, but they fail and/or loose connection, so the pin on the computer doesn't see the correct signal
