crank shaft sensor

[danlondon]

Would any one know if the crank shaft sensor would stop the fuel pump from priming as i turn the ingition on? As when i couldnt start the car yesterday there was no spark and i could not hear the fuel pump priming...
Then 3 hours later the car starts up fine again.

If the car is cold it will prob start the sensor will stop it from doing anything. Sound like you are having same problems as me it was my sensor that had gone

realy? its just so weird as i cant check it now because it seems to be working as normal now:S but im worried incase it does it again.
And when it does it will be at the most akward time and place poss.. lol

It takes 30 secs to changes its at top of your gear box so easy
Mine did same lol if you dont change it if you stall on a roundabout you it prob wont work then lol i did that

yea i guess ill change it i stalled it earlyer outside my house to see if i could get it to do it again but it wont!
Ill change it tommorow i think a few people said to me that i shouldnt stop the fuel pump from priming tho? that the only thing im puzzeled about now.

Are you 100% sure the fuel pump is not working??
Your car has to be warm to find out if the sensor is not working

yea when i turn the key on just before i turn it over you always hear the fuel pump prime and but when the car would not start when i turned it there were no noises at all so it was like there was no power to the fuel pump as well as the spark. Its all working fine now tho thats what i find weird its running perfect now i thought if the sensor was to go that would be it done?

If its not doing it now don't replace it in case its not it. you car wouldn't run if it didn't prime. Its easy to get 1 from you local garage i was runing mine for 3 months with it broken lol

 

[danlondon]

yea i might leave it and see if it goes again it sure does sound like that sensor i guess but need to find out if that would also make the fuel pump cut.
This car seems to be neverending problems...

Anyone else got any ideas?
I was maybe thinking it was the alarm i have a toad and it acts a bit weirdsometimes. it seemed to be working fine but dont they cut the fuel pump and spark when they kick in?
