Now what! Won't crank the engine...

[Caen Fred]

OK I parked a running (bad but moving on it's own) car!

And now the car won't crank, it crank fine with a clear sound one or 2 times then cut and nothing...

The battery is a red optima fully charged.

I have spark

I have fuel

I have new plugs

I have a new 60amp alternator

The strange part, if I take all the plugs out, the engine crank OK, as soon as I put even only one plug it refuse to crank ? And that wherever I put the plug !!!! This is driving me mad!

Have you checked your battery cables ?

Do you have a good clean ground ?

Turn on the ignition, with the e-brake on and the car out of gear.....

- Take a wire or screw driver and bridge the positive wire from the

battery to the starter to the solenoid terminal on the starter (two inches away)

- If the motor turns over fine then the next suspect is the ignition switch.

The cables are checked and fine.

The starter crank the engine fine one turn, it's when the compression is building itself that all appears to die. If I crank it again just after it does the same thing. Strong one crank then nothing. It only wants to turn the engine with all the plugs out:confused:

The battery is full and 3 month old.

Maybe your starter is toast, just a thourght.

The car cranks when there is an outlet for the air in the cylinder (plugs removed)...

perhaps an issue with timing?

If your pistons are rising (compression stroke) when the valves are closed, as opposed to when the exhaust valve is open, perhaps that would cause the problem.

the car started again for no reason:lick:

I have just put the plugs back in...

I hate it when the hick-up goes away without knowing what the trouble was.

Well I see tomorrow if it will start it again.

That's either a bad starter or flaky ignition switch.

I would try putting 12 volts to the solenoid with the ignition on...
