Hi there got a bit of a problem

Changed the spark plugs on my 04 sti and went to start her up.. Engine cranks but wont start. Sometimes it sounds like its trying to kick in but just wont.

Things ive checked so far:

All plugs and coils are in tight
Plugs have a spark and fuel is getting to them
Its not the battery ive tried a couple of fully charged ones
All hoses and maf are plugged in

Is there anything else after these i can try? Getting to the point now were im going to have to have a mobile mechanic look at it

Btw the new plugs are ngk bkr7eix and car ran fine before plug change

Thanks for any help

I would suggest putting the old plugs back in and if it fires up you know it's the plugs at fault

unless there all faulty (which is very unlikely) then i would say you just must of disturbed somethink else why changing them. even if 1 or 2 was fault it would still start up. just run lumpy. check all other connections on car... i had a similiar problem after putting engine in. turned out to be pin on crank sensor bent. so was not getting connection

Pretty sure the plugs should be pfr6b or if it's moddified pfr7b.

Simplest jobs are always the hardest yes i had put 2 of the coils on the wrong plugs feel like an idiot..

Thanks for the help though if anyone else has this problem it is usually something so simple that you often overlook it
