#1: Engine starts but cuts out - just changed injector seals Author: samthompsonjr, Posted: Sun Sep 30, 2012 3:59 pm ---- Car has idled erratically since I bought it a year ago, but generally driven fine. However, decided I wanted it fixed, and came across a dozed seal and loose injector (injector 4). So, took all injectors out, replaced seals, refitted correctly and tried to start car. It starts, but cuts out within 2 seconds.
No amount of checking and rechecking has helped. There is no engine management light burning. Fuel pressure in the fuel rail is good (as evidenced by when I press the release valve - it fires out). Checked all earths and they seem fine. Plugs were replaced 4 months ago.
Effectively, I had a car that was running well save a slightly erratic idle, and now the b*****d won't start at all. Anyone else had similar problems when working with the injectors? I'd appreciate any help... it's got a year MOT and I quite fancied getting another year out of it

i had wierd idle and little power and also cut out.

*impedance (Ohms)
Should have well-cleaned the injectors one by one while they were out.
Check the injector harness connector at the back because visibility is poor and it might not be pushed home.
#6: Re: Engine starts but cuts out - just changed injector seals Author: samthompsonjr, Posted: Mon Oct 01, 2012 7:59 am ---- The injectors were soaked in injector cleaning solution, and well cleaned out. They are all firing (I took them out of the engine head attached to fuel rail, and turned the ignition - four sprays of petrol on newspaper in front of them). Checked all connectors and they were all sprayed with water repellant in case damp had got in.
Is it possible that that s***ty Sagem coil pack has burnt out the ECU?

Not WD-40 I hope..
Good that you cleaned the injectors.
I think maybe you've disturbed something when doing all this (essential) work. Double-check everything and dissconnect battery (proper procedure if it's mux car) for 30 minutes to reset the 'adaptation' of the ECU after all this.
Your servicing might have made such a big difference that the ECU needs to re-learn the auto-adapt parameters.
Worth a try.

Battery was taken out to charge overnight - I'd turned the engine so many times it ran it flat twice.
Took it all apart and reassembled twice, and still nothing. What it actually does is start, rev to approx 1200, then immediately die. Have done all the fuel rail priming techniques to make sure there's plenty of fuel pressure too.
If a sensor had failed, am I right in thinking the engine management light would be on and I'd get a fault code too? It's so frustrating, no clues at all. Sounds like its about to run like a dream, then boof.
BTW, appreciate your help a lot guys. Awaiting some response is the only thing that stopped me taking an axe to the shitbox

Not necessarily, have you scanned it for codes?
If not then it's the next obvious move really unless anyone has any other ideas.
#10: Re: Engine starts but cuts out - just changed injector seals Author: samthompsonjr, Posted: Wed Oct 03, 2012 6:55 am ---- no codes I'm afraid
#11: Re: Engine starts but cuts out - just changed injector seals Author: V9977, Location: Athens, GreecePosted: Wed Oct 03, 2012 6:58 am ---- Check the earth strap near the ECU area, and from the battery to the gearbox, and that other yellow/green wire bolted onto the gearbox.
