Crank no start
Hello all, purchased an fc vert na with a 13b. Has crank no start issue. It's an 88. So far has fuel and spark that I have checked. Anything else I should look for aside from air and compression? From what I was told the rear rotor was loosing compression as t was smoking on cold start but hasn't turned it on in about 6 months. Thanks

Have you tried any methods of deflooding the motor? When these motors get tired, they get harder and harder to start. You can pull the EGI fuse and dry crank several times. Depending on if/how badly it's flooded that still may not be enough.

If it doesn't start when push starting that would make one think the compression is a bit awful. You could always try using a tad of starter fluid (1 to 2 seconds at most). And pressing down on the throttle to deflood is only for an S5 (89-91) and not the S4 (86-88).

Have you done a compression test? I know you were told the compression was questionable, but you may want to quantify that. |

Unless he's using an Rtek. Given the lack of information it's anyone's guess.

How do you know the engine is getting fuel. Fuel might be coming from the feed hose after the fuel filter, but the primary injectors might be clogged. If it starts up briefly with the use of starter fluid then the primary injectors could be suspect.

You need to clear the engine of any excess fuel,and that means to remove the plugs.
Pull the EGI fuse out(engine bay fuse block)..roll over the engine with plugs OUT for 30 seconds. now squirt in a bit of oil(like a tablespoon) in the spark plug holes. Roll the engine over again for 10 seconds. Put in a Set of CLEAN or NEW plugs,Put the EGI Fuse back in and try to start it. IF the engine is just flooded and was in good operating condition it should want to or will start up. |

jumper the pump test connector and turn the key on while listening to the top of the fuel tank.
