    Volvo 5.7 gxi c No Start

    A hard stop like turning the key off, or a hard stop with a clunk. A clunk would mean water in a cylinder or two and might have damage to rods. Don't bother with draining water, I just would like to know IF there is any water in the cylinders.

    3.0L hard starting when warm

    The TKS carb has a module which when the engine warms up, the module closes off the port which gives the motor more fuel. The motor needs more fuel when cold but is flooding when warm. Check the 20 amp fuse, it provides 12V full time. Motor is stated and oil pressure builds which applies a...

    Volvo 5.7 gxi c No Start

    Yes, head gasket, head, block or exhaust manifolds When it died, hope it died gasping or sort of slow and not a rock hard stop. The thing that's puzzling is you have spark and gas down the TB won't even hit once. Not hitting if water is in the cylinder then that can help explain it. A lawn...

    Volvo 5.7 gxi c No Start

    Gas mixing with water will smell like gas. Remove all the plugs and note if any still look wet. Gas should evaporate but water won't. With plugs out spin the motor over to see if anything comes out of the plug holes.

    Velvo penta does on water

    It could be the exhaust is mostly plugged up. It runs on land because there is no back pressure. In the water the exhaust builds up and is unable to be fully pushed out

    2010 Tahoe q4 4cylinder

    Your Tach is off. Your motor won't turn 7000 rpm without coming apart. If your not a WOT then my guess is your closer to 3800

    Frustrated fuel

    There are no differences between auto and marine coils. That said its hardly ever the coil, but you do want one with an internal resistor, not one that uses external resistor

    1992 Rinker Captiva 186

    He's meaning that the cap was being held about an inch higher by the screws. When all screws were removed the top dropped down slightly. It will need to be held up to reattach

    Velvo penta does on water

    If accurate 700 to 900 is more then enough to keep it going. Its a real puzzler

    1996 454 thunderb ign thompson wont get on plane

    This is what I didn't understand. Now that you posted a pic of the Dizzy it's a Delco EST (3rd pic) The connectors showing would be from a EFI wiring harness. Could be the PO either used a EFI harness to replace the one on the motor, or the EFI components where removed and a carb installed...

    120 Mercruiser 2.5L - No spark

    Points don't spark The points are not grounding the coil when they close or there is no power to the coil. With 12V on the + side and grounding the - side a spark will happen. All the points do is ground the - side

    Volvo 5.7 gxi c No Start

    Those are some high compression numbers, new motor are around 150. Where any of the plugs wet as in water found? Could just be the gauge Have spark and have fuel pressure. Will it run if a very small amount of gas is dribbled in the throttle body?

    Velvo penta does on water

    Except for the one cylinder the numbers are good. Most likely a valve issue The one cylinder should not cause it not to run in the water. What is your idle rpm, 600 ?

    EFI specs for techmate pro

    It should be 19 because the ECM sensors use a ground wire, where temp gauge sensors use the body as ground
