Injector cleaning
Turbo Mini Forums

Has anyone any experience of getting injectors cleaned?

If so, any recommendations for somewhere to get it done.

All 4 of mine won't fire. Wiring and fuel supply is fine, so I'm assuming they're old and gummed up. Unless there could be any other reasons for them not supplying any fuel??

I use these people:

You get a test certificate giving actual flow rates as well.

However, if all 4 are not firing, then it would suggest that something else is wrong.

That's what I was thinking, but all 4 have a live feed when the ecu powers up, and all 4 ground at intervals when then the engine is turned over???

Rig up a 12v feed an gnd
with a push switch.

rattle them with the handle of a 3/8th ratchet whilst applying power. assuming they are just gummed. but all 4? im going with a wiring issue too.

Have you checked their resistance with a DVM, ie. to see the coils inside them are OK ?

Also, are they matched to their original ECU or is it an aftermarket ECU (high z and low z setups are different) ?

But, as already said, all 4 ???

Schrödinger's cat - so which one am I ???

I had that thought after I posted this.

Its an aftermarket ECU. Having checked, the old injectors were high impedance, new ones are low! 😖

ah...

I belive in a lot of cases you casn get away with adding a 10 ohm in line resistor... assuming you havent fried the ecu outputs.
