What should fuel pressure be when fuel pump is off?
What should fuel pressure be when fuel pump is off?
After some additional education via the internet, I came to the conclusion that fuel pressure wasn’t being held once the fuel pump was off. Fuel pressure gauge indicates that the fuel pump is providing 35psi at idle and throtlling up gives it another 6psi or so.
What’s the fuel pressure on a Nissan Leaf?
Now the pressure begins to build, but only 5-10 PSI. After 5 or 6 key ON’s, it finally gets to 43 PSI and holds steady. Now I release the grips to un-pinch the line and the pressure drops fairly quickly, back to 0-2 PSI within a couple of minutes max.
Is there a Nissan Maxima Club of America?
The club for Nissan Maxima and Infiniti I30 / I35 owners, and the official home of Maxima Club of America! Hello All. I’ve got a 98 I30 with a starting problem.
What kind of engine does a Nissan Maxima have?
In 1989, the Nissan Maxima was used the VG30E with variable intake plenum. It was improving torque to 247 Nm (25.2 kg·m, 182 lb⋅ft) at 3,200 rpm. The VG30E has a cast-iron block with a four-bearings crankshaft supported system. The cylinder bore is 87.0 mm (3.43 in), piston stroke is 83.0 mm (3.27 in) and compression ratio rating is 9.0:1.
Why does my fuel pump run at 43 psi?
With Ignition ON, fuel pump runs for @ 5 seconds at 43 PSI and then shut down automatically. This will allow fuel pressure to build in the line minimizing hard starting problem. You are correct in your search, Scotty. Loss of fuel pressure may be due to faulty check valve (in pump assembly) or Fuel Pressure Regulator-Fuel Injector.
When did the Nissan Maxima VG30E come out?
On April 1987 the “W” series VG30 was released, the output power was increased to 165 HP, but leaving torque unchanged. In 1989, the Nissan Maxima was used the VG30E with variable intake plenum. It was improving torque to 247 Nm (25.2 kg·m, 182 lb⋅ft) at 3,200 rpm.
