Riddle me this.. Have spark, have fuel, don’t have ... ???

2000 Volvo c70 2.3 hpt, started backed up 10 feet, yes lawnmower syndrome, and it wouldn't start back up, all of sudden the cranking sounded like just starter spinning figured i need new one of those why not... install new starter and same quick spin sound.. noticed the crank is turning and the cams are as well but no compression.

1 tbs of oil on each piston ... check
new plugs.. check
Fuel, oh no problem there... check
tried letting it dry out ... check
removed MAF .. check
Cranked will in anti-flood check
kissed it and talked nice to it.. check
done timing on it 5698 times plus... check

is there anything that would cause this to not want to gain compression back, a vacuumed line, valve regulator, I’m going with the theory it has too much gas and just keeps staying flooded... I hope.

it’s almost as if there is an internal safety on that is not allowing it to fire.. oh and i have had a few small toots from the tail pipe nothing i would call big back fire but enough you can hear it every now and then.. but no loud clanking can turn motor freely and the biggest thing is the starter is spinning the motor and cams..

please help .. I’m stuck in SC

Look for information about the key ring. I have heard of that failing in the cars of that year frame.

The ETM cars are really stupid if you flood them.

Unplug the injectors and do the oil trick again until you hear the cranking slow down. Plug them back in, and then try holding your foot down on the gas a bit until it begins to catch.

Are the spark plugs fouled with gas, or have you confirmed that the plugs are actually sparking?

yes i do have spark, I can't find anywhere the timing of spark from the ETM but all 5 do produce a blue spark every second or so, I let the car sit in the hot sun all day and will try the oil trick again, I think part of my issue was i kept trying the floor clear flood trick.. well i discovering to just remove the injector rail and turn over facing the wall it was like a show at vegas if you think your not giving it gas ... BOY was i wrong I think im officially riding the lawn mower to work vs the car.. enough gas in the oil it could blow if i got hot enough. and yes i will change the oil once firing again.

So the only thing you may be missing is the ETM holding the throttle plate open according to the angle of the pedal.

Remove the airhose from the air cleaner & ask someone to view the throttle plate while you're cranking. Is it changing angle with the pedal? If not hold it open with an object & crank.

If the starter sounds too fast and all belts, cams are turning too easily the engine lacks compression. Might be time to drop more than one teaspoon in.

I did remove the injector wires and put oil in and im getting a bit more deeper sound and some new backfire but just not enough catching to start to push stuff out, does anyone happen to know what the timing on spark should be to me it seems slow i.e. fire................................fire...........................fire.
it may just be that way but I have usually seen spark go... fire..fire.fire.. very quick rapid.

and the throttle plate I would assume this is the box under the intake manifold, its pretty sealed up except for a air pipe coming off the intercooler. Is this what i need to check, i hear something from that area opening and shutting when keys are set to position II

im going to bump up the oil in I would assume with extra oil it will start to push out the exhaust causing extreme burn smoke ...

If you remove the injectors to put oil in this is unlikely to reach the rings. The turbo pistons have machined recesses and the oil is likely sitting in these recesses. Also most of that oil is likely soaked in to the inlet chamber and the rear of the valves.

Remove the spark plugs, clean the oil off them and place the oil accurately toward the side of the piston with a oilcan nozzle.

The motor should slow down and sound as though pressure is built up. Also when you crank ask somebody to block the exhaust with their hand. You should feel quite a bit of back pressure build up (if there are no holes in the exhaust) and this will indicate the presence of compression or otherwise.

thanks for the info and tips, i let her dry up all day and i followed all the above directions, im still with out compression i had the plugs and injectors out and replaced the ignition switch just as a what if and it started to sound deeper like a motor with out plugs in it, then when i went to giver her a full battery got two pop backfires then back to the old spinning, at this point i am wondering if Lawn mower is not the case and if so what would cause me to knock out all 5 at the same time by just trying to start it? Head gasket? Blown vac line??? sensor? ETM failure?

I still am very curious about my spark it seems solid but slow is the spark just in timing with the injector and what could cause the two of them to go off sync, i am about to make my own 4th of july fire works and line up 5 spark pulgs with caps on them grounded out and turn over the injector rail and see if they are in sync.. I know fire and fuel dont go well but my neighbor is a fireman i will let him know on the safe side..

I realy think i keep flooding it over and over and like precopster said i am putting the oild down the spark plug holes but can still see the oil sitting on tdc when it comes up.. so its not going around the sides but i have no compression??? stuck open valves?

please help before i do something dumb like get a new motor!

well took the head off after trying everything and come to find out it jumped timing and valves went boom boom bent..

That'd certainly explain it. Well that sucks.
