ive just started the car for the first time since doing bigger turbo and injectors ect ran for a while then fuel started to come out of the downpipe any ideas

What injectors have you fitted?

Have you made a hole after the MAF to trick the ecu?

You would be best to ask scoff or haz as to what size you would need.

tjhere off a bigger volvo about 300cc each ive not mapped ect yet just wanted to get it running first not sure if the chambers should fill up like that though and spill out the exhasut

which ones? the greens? have you fitted the resisitor pack as it'll blow the outputs if not and injectors stay fully open everytime the ecu is turned on.
easiest way to trick the ecu for starters is to use a dv sized take off pipe between air filter and turbo

ive popped the rail and injectors off the engine and they are firing constantly on turn over any ideas ive even swapped the injectors back to the standard ones and its doing the same and replaced the small length of wiring loom

just changed over my ecu the jetronic one and its sorted out the problem nice easy fix

ah, if its firing constantly you've probably blown the outputs in the ECU.

check that you are not using low impedance injectors without a resistor pack - you will blow the new ECU too if you are not carefull. you must use high impedance injectors, or low impedance with a resistor pack.

They are 2.4 ohms across the injectors
