I have a 1994 Nissan Sentra LE with a 1.6 GA16DE engine with 103,500 miles.
I began to have a starting problem some time ago, and found some bad injectors.
Recently, a new start problem began, and I found a leaking injector o-ring.
Now, checking fuel pressure, when I turn on the key, the needle goes up to 43 PSI, then instantly falls to 10 PSI and slowly bleeds off to 0.
I see no leaking o-rings or injectors now and the engine runs very well, but is still a bit difficult to start at times, having to hold the accelerator down.
I suspect the fuel pump, but is it possible the crank sensor is faulty, cutting the pump off?
Any other thoughts would be appreciated as well.
Thanks
Chris
