ive put a new engine into my 94 wrx my car was an import but the engine i got is a uk one.ive rewired the loom so the plugs are now sparking but the car still doesnt start,and petrol is getting pumped in.also ive sprayed petrol into the manafold and it does start until the petrol is burnt away. so any suggestions? maybe injectors arnt spraying

 

may sound like a deft reply but have you got the 3 fuel pipes the right way round?

 

lol yes m8

 

does any one have a import wrx with the top mount intercooler off and can post a pic of the plugs ontop of the gear box directly under the intercooler thanx

 

Are the injector/coil pack plugs connected in the right order?

 

id say check the fuel lines are round the right way, if not then id say injectors, did you put the jap ones on the uk engine?

you'd at least get some coughing and backfiring if things werent in the right order.

edit - if you say it runs when you spray fuel in then i defo say injectors.

 

the engine has done 40k miles and the injectors and everything were alreadiy in place so i assumed it would all be good.but the injectors are electric that lead up to the wireing underneath the intercooler

 

any other suggestions?

 

can anyone help?

 

did you check the above, ie injector/coil connectors. Did the earth on the inlet manifold go back on, the one by the fuel filter? Is your fuel pump priming the system when the ignition is onn before starting?

 

spark plugs are sparking fuel pump is working fine crank sensor changed and earths look good?and there is fuel in the fuel rail so............. maybe fuel injectors aint working sumthing electrical maybe?

 

So, you get the 2 second fuel pump prime?
You say you have a spark, doesn't mean there in the right order. Check the black connectors are joined to the rear plugs, grey to the front. Same for the injectors, if i remember, the dark grey are the back two, light grey the front.
If either of these are wrong, the plugs/injectors will be fired at the wrong point.
Have you done an error code read? Two black connectors under the dash?

 

Im not a 100% on this but does the import injectors not run at a diffrent voltage to the uk ones. I think at a lower voltage hense not opening injector. No doubt someone with a bit of knowledge will correct me....

 

the error code doesnt work unless the car starts tho.f4lak could be onto something tho its a possiblity no? thanks guy keep it cuming

 

right code 24 and 31 are cuming up on the engine diagnostics any ideas?

 

nope not them^^^^^^^

 

when i fitted a uk spec engine into mine i kept the jap spec manifold with all the jap spec running gear ie injectors etc etc and all is well might be a compatibility problem with the uk spec running gear maybe?

 

ive just changed all the sensors only thing left is injectors that are uk so........ im going to try them

 

not 100% sure but dont think a jap ecu can run a u.k engine all the emissions are different and different voltages supplied.Fuelling set up is also different so maybe not getting enough fuel to start engine and probably not enough voltage to open injectors.

 

ive put the uk ecu on that came with the engine

 

Hi, you say you re-wired the loom, did you swap both the cam and crank sensor wires on the ecu plugs?

 

no i didnt should i have?

 

the uk and jap ecu's have different pinouts for the cam and crank sensors, 2 wires need swoping over.

 

i have a uk ecu plugged in but same jap loom in car

 

and i have the uk engine loom from thre car the engine came out of and followed all the wires back to the ecu and then to the engine

 

ah, you should be ok then.

 

yeah but still no go

 

any other thoughts guys can some one post a pic up of the fuel filter hoses connected to engine please

 

shes working now guys not brilliantly as its misfireing but it does run
