2002 S80 NA will not run longer than 10 seconds

Post by Drdave007 »

got this 2002 s80 very cheap because no one could make it run, I think i am a competent technician, has fuel pressure 55-60psi,
injector pulse good,swapped injectors,ignition firing on all six coils, timing belt in time and hasn't been messed with. will run for ten seconds then sounds like it leans out, spraying carb cleaner makes it worse but plugs not fouling. if you grind on starter it will almost crank sometimes but sounds like its a tooth out in timing or real slow. compression 100 pounds . any ideas???? all help am very thankful for.

Try a new crankshaft sensor would be my first idea.

MAF ok?
Precat O2 sensor ok?

Did you do a scan with DICE?

On my old 2004 S80 2.9 NA that I gave my sister, after much digging and searching her problem was a clogged CAT.

Try taking out an O2 sensor and having a look - maybe a couple of well placed rubber mallet hits to listen for honey comb issues.

Which engine is fitted? Turbo or non? 100psi for a non turbo is almost a dead slug.

I am not so quick to call the engine dead because of the compression test. You have to eliminate a few items. First put a half of a cap of oil in each cylinder spark plug hole with all the plugs out - cover the holes with a rag thrown on top. Spin the engine a few times then let it sit a few minutes and redo your compression test. Your numbers may be low because the engine has not run in a long time. Worth the time to see if you can get the numbers up before calling it dead.

Miles on the motor and condition of the oil? Did you change the oil? It could be full of gas causing your problem with compression. Drain oil and look for metal sparkle, a sign of mechanical issues.

Unfortunately you have no history on the car as it would have shown signs of compression lost. Do what follows before you try adding oil as it will cause a false positive. You first have to look for signs of burning oil.

Visually inspect the exhaust tip for soot (sign of oil burning) and the spark plugs. Then shine a light down and inspect the piston tops, but do this after you have the plugs out for about an hour so any unburned gas can evaporate.

Report back, but I would also look at your exhaust pressure as I mentioned before.

I am not a doctor nor a Volvo mechanic, but McCoy was.
