    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

    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 ?

    Therm for 4.3 Merc 807252T2 or 8M0109441 ?

    They are the same part, both are 160*F Merc may change a design or iin most cases, it changes vendors so the part number is changed to keep track of configuration. In any case you can use either and they both work the same

    EFI specs for techmate pro

    That sounds like the Engine coolant Temp (ECT) sensor and or the Manifold Air Pressure. You may even have a MAPT (MAP with Temp). When cold the ECT should tell the ECM that its cold and give it more fuel, just like a choke on Carb. When cold the IAC should be allowing more air since there is...

    120 Mercruiser 2.5L - No spark

    I'm wanting you to verify that the points do open and close. This is the reason to loosen the dizzy, don't remove it. If the points do open and close then they will work. I want you to hot wire the coil just to find out it does run, disconnect jumper wire to turn it OFF. If it does run, now...

    2001 2960 with dual 5.0 GL PEFS Motors fuel issue

    Others opinions may vary but there is no vapor lock with a carb. Your motor is warmed up and after shutting down, it may be leaking or evaporating fuel from the bowl, but the fuel pump should refill quickly. What might be happening is the power is not making it to the pump. VP uses diodes and...

    7.4 MPI Stalling wont idle.
