1995 Lexus GS 300 starts and turns off ride away


Asked by Aug 07, 2016 at 01:43 PM about the 1995 Lexus GS 300

Question type: Maintenance & Repair

I disconnected the gas line underneath driver door
when I turn switch on no gas comes out only if I
turn key over but it comes out slow with no
pressure could it be my full pump not working...
How can I tell how check pump if it's good or bad...
And how much pressure it needs to send out cuz to
me it feels and looks like not enough pressure to
get to injectors ........

When you turn the key to the on postion you should get a strong stream of fuel for about a second if not bad fuel pump or clogged fuel filter


Connect a gauge to the fuel rail check the fuel pressure, how many PSI Fuel pump time likely '95...21 years is decent life for a pump.
