Hesitation than cleared itself - ZR-1 Net Registry Forums

Took the car out again tonight...I'm reading that the car runs off the primary fuel pump once the temp reaches 176 degrees...

After about ten mins or so the symptoms started again.....Very rough running till I hit about 3,000 rpm than it would jump...

Im thinking maybe the primary pump is going.......What's the easiest way to check this? If it is , don't the Z use the same pump from a 96 Chevy suburban?
