98 Tahoe wont start w/o starting fluid

[cecilville]

The Tahoe runs great but wont ever start unless starting fluid is used. Cant find any leaks and have 40 lbs of pressure before starting and 50-60 after running. Does have a po122 trouble code but its for TPS. Will that cause no start ?

Usually the starting fluid means battery voltage is low or pump pressure output is low.

Thanks for the input. thought that might of been the issue. good battery output so I will attack the pump

Might put key in run position a few times and then crank it to see if it starts, still sounds like pump....
