93 Altima stalling at random

haynes manuals are not even fit for recycling fiber, let alone trying to impart vehicle maintenance data. suggest either getting an online subscription to alldata, or going to your local library and using their subscription or dead tree factory service manual

Haynes and Chiltons were both pretty good back in the pre-ECM days.

Some of them that cover only a couple years of one model are still an OK item for the DIY type who wants to change the oil, replace lamps and such. The rest that cover 5-10 year segments and have an abundance of the phrase "other versions similar" are one step over toilet paper in relevance. Nothing like saying that a vehicle that had 10 different engines, 5 different transmissions and two different body styles during that time are the same....

Alldata DIY is pretty good. The new version of the help section on EBSCO is a waste of time. It used to be pretty good but now they have edited much of it down to the point that for anything past basic items it is junk.

I think it's your ignition system.

Not quite....

Haynes back then was very much a British company, with British experiences. Their engine-control information was often completely wrong for North American emission-controlled systems, especially when it came to carburetion. All their manuals were generated during a tear-down of a UK- market vehicle, with North American information being pasted on after-the- fact, and from unreliable paper sources.

Chilton's strength was the same as Haynes: Their home market. Being American, Chilton's was good in the pre-emissions days for American cars, when American carbs and engine controls were a LOT simpler. Chilton's foreign offerings suffered from the same faults as Haynes.

The only thing that's really reliable these days are the various manufacturers' Techinfo sites.

even those have mistakes. honda's complete absence of diagnosis on their main relay problems, their misdiagnosis of the evap code issues on the accord blaming a solenoid when it's the fuel cap and blaming a civic's thermostat for torque converter lockup issues when it's actually the gear selector switch being a few examples.

I liked the Haynes manuals. There was a lot of pictures and some of the wording was humorous and educational - words like "bonnet" and "wing" and "adjustable spanner." OTOH, the English probably thought "monkey wrench" was a hoot too. I even found the manuals useful. I was thinking about getting a Jaguar XJ6 because used ones were going so cheap. I bought the Haynes manual and what I saw pretty much dissuaded me from getting one of those mechanical monsters. Thanks Haynes!

you think the 6 is bad, try the 12. a friend has an xj-s - it's got to be one of the last original jag engine running examples [as opposed to 'vette converted] in ca because it's such an emissions/reliability nightmare. [all with a mix of fractional and metric fasteners!] it's taken him nearly a thousand hours of work over the last few years. i think he's out of his freakin' mind.

Get the XJ12 manual, it's even more hilarious! For God's sake don't actually get an XJ12, just get the manual...

"Jaguar V-12" has a magical ring to it but I suppose you're right about your friend's state of mind. :-)

I could see myself owning one but I'd also have to imagine myself as a rich English twit living in a castle in England in order for that to make any sense at all. :-)

Can you see yourself in a smoking jacket with a glass of cognac, saying "Don't worry about that, I have a carburetor specialist on staff?"

As an XJ12-owning buddy/boss of mine said; If you're going to buy a Jag, buy 2; you'll have 1 to drive while the other is in the shop.

But, man, that was one nice rig when it wasn't being worked on, I drove it every chance I got! -----

I used to enjoy working on carbs. It was relaxing - like working on a small appliance or electronic equipment. The first one I ever rebuilt was a big Mazda rotary 4-barrel. As an added bonus, you get to inhale a lot of solvents. :-)

Update after a week of driving - NO STALLING!!!!!!

Seems the oil change made the oil pressure sensor work properly again.

Thanks!

I would still replace it. If it's that touchy it could fail any time.

I think more likely the vehicle just was low on oil, and the oil in there was tar. The oil pressure sensor probably did exactly what it's supposed to do, which is to say it prevented the engine from wrecking itself with no oil.

Could all be a coincidence or unintentionally faulty observation.

Fuel pumps can and do cause intermitent problems in concert with ambient temperatures, level of fuel in tank, wiring connections ... before they may fail utterly.

The advice to start throwing parts at a symptom, based solely on a non-skilled observers reportage, and without any attempt to first diagnose and verify an issue via testing or other gathering of data, is one of the surer signs of a novice, poseur or other incompetent.

did you check on the altima's control logic - whether the engine computer really does shut down fuel delivery if it registers insufficient oil pressure?

none of those are relevant if the ecu's shutting it down.

if the ecu logic is as described, and this is a commonly occurring issue, then "investigation" of the oil pressure switch is entirely relevant. and if, as is the case with most people, myself the tool geek included, someone does /not/ have pressure testing equipment for oil switches, then the cheapest easiest way to check the switch's operation is to replace.

now, if your [perceived] protagonist actually has experience of these switches failing, and based on his description of their failure mode and what we know of how these switches are constructed, it would appear that he has, and when this unit's failure appears to be a known problem per: then again, replacement is very sound advice.

to conclude, failure to d.a.g.s or check on other easily available facts doesn't give any grounds to start using words like "novice, poseur or ... incompetent". not without hypocrisy.

At the danger of monotonously repeating myself ...

Immaterial. Because a particular fault CAN result in a specific symptom doesn't constitute that it has.

See my remarks in a previous post, re: de-energizing the pump inarguably results in a loss of pressure, and if a loss of pressure is verified, the question becomes - why.

Correct. Investigate. Simply guessing and replacing parts sans any diagnostics whatsoever epitomizes the amateurish approach.

That's quite the rationailzation for one not having either the knowledge or tools to competently effect a repair.

Really? Another's opinionated forum post is actually offered and intended as support documentation?

Hardly. "Because a particular fault CAN result in a specific symptom doesn't constitute that it has." But the endless replacement of a sufficient number of suspect parts with those known to be good CAN eventually solve a hardware related issue.

"The advice to start throwing parts at a symptom, based solely on a non-skilled observers reportage, and without any attempt to first diagnose and verify an issue via testing or other gathering of data, is one of the surer signs of a novice, poseur OR other incompetent", as well as each of my other comments, are self- evident and have been neither convincingly nor effectively refuted.
