No code and engine died.

billsmartis · 01-07-2013, 01:01 PM

I have this reoccurring problem that the engine dies for no reason and no code. If it's under load it'll die over 2000 rpm and not under load it'll break up and carry on over 4500 rpm. I checked the EGR valve and it moves freely and cleaned the tube from the EGR to the intake manifold. Installed new gaskets on EGR and EGR tube. Again I get no codes while this is happening or after the fact. The cam sensor is new also but again still no cam sensor code. Does anybody have any idea whats going on?

A possible lack of fuel? (pump in-op or filter clog)

Can you get it to fire back up w/test fuel (starting fluid)?

No codes would steer me in that direction, for if a spark issue, I'd assume you'd see "mis-fire" codes on a scan.

Are you checking for codes in "History" too?

A 2000 2.0L Tracker folks.

It started up and got me home where I did the rpm tests. There are no codes since I cleared them last time. All this happened about 20 minutes ago and wouldn't it code out a fuel problem if your suspicions are correct? I tested the fuel pressure when I troubleshot the last cam sensor went south and it was about 45psi. I seems to run ok until it warms up.

You would think so, but I'm not sure that you'd get a lack of fuel pressure, injector or pump related code. I've never heard of one to date at least. Yes to a mis-fire ("random" proly) code though.

If it dies again I'd be prepared with a can of starting fluid AND a way to "wet rag" the CPS.

Actually the cam sensor is brand new and has very little time on it though this problem is symptomatic of a bad cam sensor except for the fact it starts shortly after the stall and I always got a code for cam sensor failure.

Oh I'm with ya', that's why I'm initially thinking fuel starved.

Quick question does the fuel pump run all the time or does it shut off when pressure met? I asking this because I'll have some time off work in about 3 weeks for 3+weeks because they found cancer in my one kidney and wanted to wait to do that until my gall bladder incisions healed. It sucks getting old

Once the kidney's out I'm cancer free because it's contained in the kidney. Getting back to my problem I'd rather spend $10.00 and be right than spend $50.00 on a fuel pump and all the work and be wrong. I also have a lot of body cancer on my '92 sidekick to take care of too for inspection...hmmm that sidekick has more in common with me than I thought but not as many problems as the 2000 tracker.

The pump runs only to maintain fuel pressure at the rail. If you have it (pressure) then you can rule out the pump UNLESS the pressure / flow is falling off due to a restriction or pump problem when the engine is at a higher than idle fuel demand. That's something difficult to observe unless you have a remote / in-cabin way of observing the fuel pressure while operating the vehicle at speed.

Best of luck w/your follow on surgery and general health Bill. Yep. Getting old sucks. I'm looking at back vertebrae fusion surgery in one location right now.

Ok I got my fuel pump and I am ready to drop the tank this week. What do I need to know about disconnecting the fuel lines from the gas tank? What tool do I need to remove lines from tank?

Max · 02-24-2013, 05:51 PM

I don't believe that you'll need exotic tooling. Check the Service Manual to confirm.

You will want to have a minimal amount of fuel in the tank from regular usage and then removing whatever you can via a siphon or pump. Fuel weighs around 8 lbs a gallon, so do the math.

Also, you'll want to bleed off the line pressure by pulling the fuel pump relay or fuse. The procedure is in the Manual as well.
