Hi can some one tell me how to turn the engine over on my 94 sti with no spark seems somethings left the engine and done my turbo i need to do a compression check ........... i hope i aint done a piston i know i burnt a plug well two for some reason .... so if someone can give me some info on the ignition,price of piston and y i might of done the plugs i'll be greatfull..

 

Sounds like you need to phone the AA mate

 

Thankz for that Wilster i cant see the AA helping they couldn't find their **** with both hands.... i need a answer real fast as i want to get on and get it sorted so anyone that has something construtive to say please post

 

Disconnecting the crank sensor will stop the ecu getting a signal pulse, and therefore prevent the ignition fron getting a spark.

 

If you unplug the crank position sensor it'll turn over without fueling or sparking. It's the little sensor in the centre of the engine on the front, top of the block, above the crank shaft (no suprise there!!), in by all the pulleys. It's usually got a little brown 2 pin plug on it.

 

Sorry mate, not my usual style. I didn't have a clue what you were on about but you seem to have some proper responses now

wilster

 

its ok wilster i just think the AA are all muppets lol .....ok ppl i thought it was that sensor but didnt want to go messing with things till i found out for sure, it seems i have enough problems as it is, turbos (tdo5) going to cost £380+vat and i dont know if ive done a piston yet i need to do a compression test.....Would i know if ive done a piston whats the symptoms ??? its started smoking at traffic lights or when at idle then if u rev'ed it loads of smoke would poor from the exhaust then clear???

also any idea on price/make of piston and headset..

Thanks again ppl

 

If compression is noticably down on one cylinder..

chances are ta ta piston..

done a ring mate

 

Ok im going to do a compression test wish me luck.... )

 

Not good not good at all .......165psi on one cylinder and bugger all on suspected cylinder, Great thats all i need so its out with the engine i suppose not a bad job could be easier if i wern't 120 miles away from my fathers car repair shop....oh well best get stripping it down..

 

Sorry i ment to ask does anyone have any ideas on how this happened or how i can prevent it in the future if i keep the car that is lol
