Hi guys,
I have a 1990 Chevy pickup with a 350 in it. The truck has been setting in my garage for approx 5 years. Recently I replaced the fuel tank, the sending unit fuel pump in the tank all the fuel lines etc.

I could not get 12 volts to the new fuel pump, I found a wiring hireness problem repaired it and the vehicle started. I let the truck sit for 2 days, went out to start it and now it wont start. If I put some gas down the carb, the truck starts and will stay running.

Could it be possible that the throttle positioning sensor is bad?

Thanks.

Hello,

Is your check engine light on? If so pull codes.

Could be the IAC or the TPS could also be fuel pressure regulator.

Check fuel pressure.
