    No it dosnt turn over farter than normal, and the car has plenty of compressor. I did pullout the plugs and cleaned them off, and I also checked to make sure that each cyilinder had fire.

  • racecarboy20 Sep 28, 2009

    No, The car turns over same as usuall. I took the plugs out and cleaned them and checked each of them for spark but, stll nothing. Have you seen a problem like this before or have any idea what it could be?

  • racecarboy20 Sep 28, 2009

    I havnt done anything else to the car and, got in it this morning to try to start it. When I first started cranking it over it acted like it wanted to start and then nothing. Is it posible that the cyilinder walls could of been washed out from cranking on it so much? I have managed to kill the battery and , I had to jump start it this morning. Is there any more advice that I could be given? Its a 92 volvo 940gl non turbo with 215000 miles on it. If it is the cylinder walls that are washed out then what causes this to happen in these motors?

  • racecarboy20 Sep 28, 2009

    One other thing I dont beleave there is a problem with the timing I installed a new timing belt and water pump 15000 miles ago, but ive heard people say that the non turbo motors have proplem with the cyilinder walls being washed out. why dose that happen and, is that a posobility?

  • racecarboy20 Sep 28, 2009

    Thank you! Im going to check that next and see if there is gas in the oil, and if so let the cyilinders dry out! Thanks again ill keep you posted on how its going!

  • racecarboy20 Sep 28, 2009

    Alright here's an update. I checked the dip stick and it did smell like gas so I pulled out all the spark plugs and cleaned them again. However this time I injected alittle bit of oil in each cyilinder and turned it over by hand to get the oil on the walls. I put the plugs back in and the car started rite up. The only problem is I have no idea what caused the problem in the first place? The third spark plug did have gas on it. Could that be an indication of a bad injector? Have you ever seen this before or what could of caused this?

Check your timing. Sounds like you know what you are doing and if you have spark, fuel, and comptression it should run unless it jumped time. It could be off a tooth or two and still have compression. With high milage that would be something to consider.

    Yes the cylinders may be washed down. The easy way to check is pull out the dip stick and see if you smell gas in the oil. If so the cylinders are gas washed. Pull out the plugs and leave cylinders air out and change the oil. The cause could partly be all the cranking, but check the injectors you may have a stuck one. If it is stuck open it will dump gas into the cylinder all the time needed or not. Let me know and we'll take the next steps to get you running again. I won't abandon you.

    Yes if the third plug was the main one with gas on it the injector went bad. What happens is thru age the internal seals wear out and the injector won't stop dripping gas causing exactly what you just went thru. I'm glad you found the problem and got the car running again. Now just replace the injector and your done. Good Luck!! Glad I could give you some help.

My 1993 volvo 940 has fire where should be, and gas flow where should, but still want crank can you give me solution this my problem


Ok. if you have made sure you have ignition spark at the spark plugs by turning over the engine with a spark plug wire off and held next to the block and you have also made sure your Fuel injection is pulsing and putting fuel into the engine, start from scratch.Pull out all your spark plugs,clean them off check the gap and let the cylinders dry out.The put them back,turn the key to on and make sure again that y our fuel injection is priming the system.Then spin the engine over.if you are still not getting the car to start,then you may need to check and make sure your camshaft is not broken by spinning the engine over and making sure you have spark at each plug.Try that and repost.Good luck.

I have a 1994 Volvo 940 Turbo. Just lately it has been hard to start. It will crank but won't fire. Sometimes it fires but won't stay running. At first it was doing this only when the engine was warm, but...


Spray some gum out in air flow sensor and see if it starts up.
If it does you need a new fuel pump. To confirm look for schrater valve on fuel rail, put a rag around it and wear eye protection. Push valve and see if fuel shots out while the vehicle IS NOT RUNNING. I fuel does not shoot out you have no residual pressure and need a new pump.
The other thing is to place key in ignition and put it to on position you shoulsd hear a buzzing sound from pump.

No spark


Behind the engine on top of the tranny bell housing is the crank angle sensor.  Try wiggiling the harness.

The same thing happened to my 94 volvo 960 the engine belt was having the same problem, i changed it the belt, it was fine for a few miles after that it just died, does not fire, not sure if it is getting fuel, but the mechanic says the timing belt went off. you may have to check the crank sensor on yours.

CAR SOMETIMES WONT START


you are having a fuel delivery problem...and it could be caused by numerous things...such as a bad fuel pump, a bad cold sensor or warm up injector.  You haven't attempted to  solve any of these suspected faults...so take it to a mechanic for repair

Have you checked compression on non firing cylinders? Likely has blown head gasket between these two cylinders if located side by side.
