this problem is on a FRST

hae just fitted a T3 to it, it won't start up, very thing connected, it has spark and fuel wen it's ment to get it, the wierd thing is if u take anyone of the spark plugs out it will run on 3 cylinder but it wont start on 4 cylinder

has anyone else had this problem or got any ideas as to what it is because i am stumped.

the only thing i can think of is it still has the same air filter that it did when it was running as T2, would this cause it to be starved of air??


cheers

Nope as my T3 converted FRST is still on the same filter as well and that goes fine. My guess is you've disturbed something you shouldn't have during the conversion. I would start by checking all the multi plugs out. The fact you have fuel and a spark would indicated the CPS isn't at fault

 

cheers have checked all the multi plugs are connected and the wires are all good, i jus cant understandwhy it wont start at all m8

 

you say it starts with 3 cylinders linked up but not 4 linked up????????? let me have a think

 

yea it starts wid any 3 of them linked up but u hav 2 hav the spark plug out of 1 of them for it 2 start, then if u put all plugs in etc it wont start, got me baffled

 

did u use an escort manifold gasket as they are different to the fiesta?

this might help

 

cheers m8 great help

na didnt now had 2 use a ERST manifold gasket, anyone now why you have to use it out of interest

 

i really dont know why but it says to on that guide.im wondering whether it might be blocking the flow of exhaust gases cos u say it runs with a plug out as the compression is being let out of the plug hole rather than being trapped in the cylinder if it is blocked.do a compression test on all 4 cylinders and see what they are

 

ok kewl, jus wondered, it does it on any of the cylinders tho if you let a plug out m8, gonna put ERST gasket on tomorrow and see if it makes any difference.

 

sounds like you got a vac leak or something.

have you checked fueses etc? checked for breaks in wireing/HT leads?

 

the fuses are all good and so are the vacuum hoses m8, as i say tho it will run on any 3 of the cylinders but not on four of them and to get it 2 run on 3 you have to take da spark plug out to get it to run.

 

are all ht leads and plugs working?

 

yea all ht leads and plugs workin m8, changed gasket to escort rst 1 and no difference, at this rate it gonnna get broken up

 

i really dont recommend this as i wouldnt do it myself but have you thouight of starting it on the 3 and sticking the 4th plug back in and reconnecting the ht lead?

 

tried that aswell and as soon as the plug gets in the hole it stalls the car m8, which is reli wierd, i mean i tried everything i can think of doin n still no where at the min,

was hopin someone would have some ideas i aint tried lol

cheers marc

 

done a compression test on it?

if its got a chip, take it out and try it.

have you fully charged the battery yet?

 

hav tried it with and without the chip, we hav done a compression test and they all seem the same and seem to be fine in my past experience. yea battery has been fully charged.

its jus such a wierd problem and am reli stuck with it know lol

 

ight be time to have a look under the rocker cover

 

ok m8 cheers will hav a look there 2mora cheers anyway you been a big help

 

rite just had a word with my m8 its his car not mine and he says he cant understand why it wont start was fine untill we changed the turbo,

the engine itself is 5500quids worth of full steel low comp bottom end etc and has only done 6k since it was built, it was run in with no boost for 1.5k of that aswell

cheers
