Fuel Problem
I replaced the fuel pump in my '87 IROC 305 TPI about a year ago, since then i drove it once. Started tinkering on it today and it wouldn't start (not very surprised since its been sitting for a year). Noticed the pump was not priming. Checked all fuses and replaced relay. Checked voltage at pump and is only receiving 7-8V at the pump. Will the pump still prime with less than 12V? Dont want to change new fuel pump if its an electrical issue. Please help.

Re: Fuel Problem
That's pretty low. Is the battery fully charged or is it that low as well?

Re: Fuel Problem
Disregard. The fuel pump was indeed bad. Once the motor begins to run, the voltage jumps up to around 11V. Guess all it needs to prime is 7-8V
