Urgent help! distributor has no spark??

hi all.

had my car for a valve adjustment and new spark and valve seals replaced. but the strangest thing was, after it was all done. my car wont start.

i went to the mech today, and he showed me.

the dizzy had no sparks coming out ONLY when the cover is on....

we pulled the cover off and it sparks fine!

we thought might be the covers or rotors fault. so all new parts were replaced, yet still same problem??

obviously my old dizzy wasn't at fault. so what could be the problem??

they is enough voltage going into my dizzy (11.2 something...more than enough)

please help asap thanks!!

the problem is ur mechanic lol

i really doubt it andy, he is pretty good with hondas.

anyone ?

could it be my immobilizer?

I don't think its the immobiliser because if it was armed, then in theory you shouldn't even be able to start the starter motor.

you mean the dizzy cover ? IE cap and rotor ?
did you replace the cap itself ? (it has 4 connections inside that contact the rotor , and send the spark to each spark lead thent he spark plug 1 at a time)

depends what it is immobilising.. a immobiliser is just a circuit breaker really

does the car crank but wont turn over?

check your timing as if this is way off you will get no spark!!

it could either be too advanced or vise versa!!

i've had the same problem when engine conversion was done and no spark but cranks.!! checked the timing and wala!! fixed!!

try this and see how u go ...

**immobilizer wont affect ignition spark... but can disable the starter /fuel <-- even then this has nothing to do with "no sparks"***

yes once the plastic cover on the dizzy is put on. no spark would come out.
we tested this with one of his tools which looks like a screwdriver with a tube. the tube would spark when the dizzy starts to turn.

the cap is working and a new one was even replaced. still same problem.

whats funny is, when the cover is off. we tested each connectors with the tool and they was spark!!

well wouldn't timing always be the same with or without the distributor's cover on or off?

it turns over and HAVE sparks with the cap OFF. but with the cap ON, it turns but NO spark :confused:

its weird how its the dizzy cover, have u got another dizzy cover and tried it? and if its still the same then there is definately something wrong there..

have u got ur leads checked?

the timing could be affected during the vavle adjustment.. and could possibly affected the dizzy.

as i said if the timing is wrong u wont get spark ...dont know if this applies to the dizzy cap off (as in ur case u get spark.) :rolleyes:

hmmm

^^ exactly, i mean i doubt its timing if the dizzy has spark with the cover off??

and yes tried new cap and leads and rotor....

if you look inside your dizzy cap in the centre there should be a spring loaded peice of carbon. this touches the rotor and distributes the spark to the leads.

make sure yours is not missing or stuck. it should be touching the rotor when the cap is in place.
