92 Max SE auto fuel problem when warm

Audiohire 14 April 2005 23:29:23
 Hi all. On a recent trip, after driving for around two hours, I began
to notice an intermittent power loss. I still had a good hour or so to
travel, and was in NYC rush hour stop-and-go traffic without a cell
phone. So I kept driving, at first noticing only every few minutes a
temporary power loss, which seemed to clear itself up within, say 10 to
thirty seconds. Kicking the accelerator seemed to have no effect on
when it would recover. When the car was in park, at that point, it
seemed fine when I revved the engine.

The problem progressed, though, until it began to stall out. It would
slow down to an absolute crawl, regardless of the gas pedal position,
then stall. It would then generally restart, but would stall again a
few times. I noticed that if the engine were off for a minute or two,
it would start right back up. Eventually, I was stranded a couple
blocks from home, unable to get it started again. I looked under the
hood for any obvious signs of distress, checked fluids, looked for
leaks. About ten minutes later, I decided to try to start it again,
and it started right up- only to crawl that last two blocks, stalling
regularly.

Couple things: the engine doesn't run hot- the needle stayed right in
the center through all of this. Also, the loss of power was not
sputtering, like when one cyllinder isn't firing- it was always smooth,
even while crawling. Fuel filter is a year old, looked new at last oil
change, maybe 500 miles ago. Also, the following day, I couldn't
replicate the symptom. At least, not by running the car for 25
minutes.

So, it seems temperature-related­. Fuel pump relay? Fuel pressure
regulator? Fuel pump? How can I tell? And where is the fuel pump
relay anyway?

Thank in advance

 Looks like a crank angle sensor problem, based on my past experience.

 Thanks for your response. I have to plead ignorance here- I have no
idea what the crank angle sensor is all about. I did, however, google
it (here on this group and elsewhere), and noticed that often when the
crank angle sensor was suspected, the car wouldn't start reliably. My
Maxima starts right up, even when I was experiencing the difficulties,
it would still start.

Does anyone else feel that it might be a fuel problem? Any experiences
with temperature-related­ power loss? Or replacing the fuel pressure
regulator? Or with this crank angle sensor causing my symptoms?

Thanks again.

 One more thing: I'd like to at least try to replace the fuel pump
relay, to see if it clears it up (since it's only a $20 part, and would
help me eliminate it as a cause if nothing else). I'm waiting for my
Chilton manual to be shipped to me.....but getting impatient.

Can someone tell me where the fuel pump relay is? And, if it's under
the rear seat bottom, how do I go about removing it?

Thanks again everyone.

My symptoms were that the car would start, drive normally until it warmed up
then stall. Let it cool down and the cycle would start all over again.

A fuel problem, I would guess since I am not an expert, would be more of an
ongoing issue and wouldn't be intermittent.
