To test fuel pressure on a 1999 Pontiac Sunfire, you'll need a fuel pressure gauge. First, locate the fuel rail on the engine and find the Schrader valve, which is similar to a tire valve. Attach the gauge to the Schrader valve, then turn the ignition key to the "On" position without starting the engine to check the pressure reading. It should typically be around 41-47 psi; if it's outside this range, there may be issues with the fuel pump or fuel filter.
The 1997 Pontiac Transport has 2 different alternators . One is 105 amps and the second is 140 amps. It will depend on the power equipment you have on your vehicle. You may want to get an AVR test to make sure that it is the alternator before changing it. That test is about $30.00. Good luck
