 |
|
my civic was running rough, felt like it was running 3 cylinders, so to
test which wasn't firing, i was advised to pull the plug wires one at a
time with the engine running, and if it kept going, that was the bad
cylinder. well, pulled the first plug wire, it died. started the car
again, pulled the second, it died, then the car never started again.
pulled the motor, turns out a valve was blown, missing a large chunk on
one side, so after all valves replaced, new gaskets, new rings, and a
new alternator, the motor was put back in. engine cranks over and over,
but won't start.
all plugs have spark, all cylinders have compression, and timing is
correct (not 100% sure). the cylinders are getting gas, and the intake
is opening. everything appears ok, so i'm beginning to think that a
fuse or relay is blown, or something is shorted from when i pulled the
plug wires before the rebuild.
I'd love to hear that it's possibly a fuse or relay, but if nothing
rings a bell with anyone, i'll go over the timing for the 3rd time i
suppose... |

Sounds like everything is there for it to fire.

But then you wouldn't be getting spark, right? Fuel pump is working, since
you say that fuel is going in.
The timing is the only thing in question at this point. Are you sure that
it's correct? You don't say what years, so does it have distrubutor? Is #1
cylinder at TDC when rotor is at wire #1? If it's solid state, there is a
chance that the computer is fubar and not firing when it should. Timing
would really need to be bad to not fire up at all.
Have you tried spraying starting fluid into the intake and turning over?
Does it fire at all? Anything sound like it's trying to fire up? |

Yep... A common mistake. OTOH, being a mere 15-20 degrees off can
cause you heartburn too..

Didnt see this suggestion in the previous posts:
If I remember right it IS possible to install the distributor 180
degrees off. Check and make sure the dist. rotor is pointing to #1 when
on the compression stroke at TDC.
