Hi folks. Really need your help with this one. just bought a 97 sti type r. after owning it for 4 wonderful days it done the big ends in big time. made a real mess of the engine. got a new engine at the weekend and fitted it now i cant get the thing to start. new engine is using all my own sensors, manifolds, turbo etc. checked all wiring and cant see anything wrong. it was only getting a spark on the front 2 plug leads. changed leads etc and still only on front 2. got a new coil and was getting a spark on all 4. fitted plugs and leads back in and still wouldnt start. checked spark again and back to only the front 2. keeps blowin the back 2 on the coil. any ideas? runnin outta cash fast and its makin my first scoob experience a bit crap.

any help would be sweet. cool forum by the way. matt

is the timing set up right?

matt_typeRsti

based in northern ireland.

yeah. timing is spot on. ecu related?

andyxros

cant see ecu blowing coil pack but may be shuttting off spark for some reason, fuel is being delivered to all cylinders i.e all injectors working?

did you check the spark plugs ie used new ones?
also how did you check for the sparking?
try and check the input to the coil pack there need to be two wires which switch between 12V and ground. (use a voltmeter with min max memory)

cam and crank wheels from original engine used or the new one?

i used the ones that came on the new engine. but i have the camshaft and crankshaft sensors of my original engine. tried changing them around but no difference.

examine the cam and crank position sensor pick up points / marks on the wheels.. compare to old enigne.. sometimes they break off and some wheels are different etc..

sure there is a coil amplifire in drivers side wing must control coil so that may need cheaking too??

matt_typeRsti

had everything checked today and it turns out the ecu is at fault. new ecu needed. was offered a p1 ecu. will it work?

Jolly Green Monster

iTrader: (4)

no.. p1 is a 99 ecu, you have a 97.. different plugs / pinouts / ecu etc..

both however 3 plug

Simon

matt_typeRsti

cheers. there are 2 digits on the ecu, 6S i think. does the new ecu have to match this? or will any 97 sti ecu suit?

Jolly Green Monster

iTrader: (4)

any should suit but obviously the same is better so you are sure it is correct

matt_typeRsti

spot on. thanks for all your help guys. much appreciated.
