Escort rs running problems...help plz!
Hi, ive got a s2 rs turbo engine in my xr2.... the problem is that it idles fine and drives but doesnt rev freely and doesnt boost at all but it spools and dumps but has no power??
What could be wrong? it has a healthy spark and 9 bar comp across all 4 and the timings good?
How can i test the injectors? ive tryed taking one out and cranking the car over and nothing squirts etc??
also what sensors are prone to failure that may cause this?
Thanks guys

Please help me
lol.
If it helps...im on ke jetronic fueling.
Also, the car backfires when starting and also the temp gauge reads red all the time which i assume is a shaggd temp sensor (duno which one tho!)
and also there is a sensor located behing the inlet manny that is snapped off!! (has a white and a brown wires hanging next to it and is bolted via a plate to the underside of the manny and seems to be involved with the coolant pipes??)
Also the timing seems to be one tooth out on the camshaft? ive tried to alter it but it will only sit one tooth before or after the mark and wont sit spot on!!??
Please help me, im really stuck

It may well the that the snapped sensor and incorrect timing are the problem here. Why not start there and then see if that helps.
What's the spec? Does it have an aftermarket cam?
If it idles fine and drives, there is fuel at all of the injectors. Did you hold the metering flap down while cranking? If not that would be why there was no fuel at the injector as you need to hold the flap down for fuel to pass and get to the injector.
There are a few sensors back there. There's a water temp sensor, thermal time switch and knock sensor. My guess is that the broken one is the water temp sensor seeing as the gauge just reads red. Is it red while the engine is off and ignition is on, while the engine is cold?
Try getting the sensor sorted and let us know of the cam. If it is an aftermarket cam then the timing mark on the pulley is irrelevant as it's timed using maximum lift of inlet valve 1 at a set angle after TDC.

.As far as i know the cam is standard, the turbo and actuator are also standard. the onli thing that i know has been modified is that its been chipped?
would one tooth on the timing make that much difference then?
Its got a nice fat spark but upon looking at the plugs they are quite black, so its probly getting tooo much fuel??
I also noticed that my turbo seals are potentially shafted as oil is getting thru? Also there is a small ammount of play in the shaft, do you think my turbo is shagged?
Also there is a few small cracks where the penny washer closes to in the wastegate.
Anymore ideas would be very very much appreciated

Thanks for the reply mate, i bodjed up the snapped sensor and now the temp gauge reads okie.

Where cam timing is concerned every degree counts and 1 tooth is around 5 degrees. Will the belt not fit at all with the timing marks aligned? The other thing that I have read is that not all CVH standard pulleys are the same, they have diferent ammounts of advance/retard dependant on the cam/engine. Do you have an alternative ERST cam pulley you can try?
Running too rich could also be causing your issues I suppose, worth checking!

Cheers for the speedy reply mate!
When i allign the marks and try to fit the belt its a no-no...its between teeth (it will only go on either 1 tooth before or after the bloody mark!?)
Im sure its a standard pulley as it seems to be exactly the same as my mates?
Unfoltunetly i dont have any spares about really as i usually play with vauxhalls, although i do hav a couple of complete xr3i lumps about if they would be the same?
Is there something thats likely to cause it to run rich though? Is it likely to be something like the tps (i know on vauxhalls its known that it can stick at full throttle enrichment and cock everything up lol!) i just dont want to randomly start replacing things tho lol!
So you dont reckon its likely to be the turbo then mate?

Also sometimes it struggles to crank...it hydraulically locks briefly and it also sometimes has chronic explosive backfire on cranking like a bloody gunshot!!! (the neighbours fucking hate me lol!!)....Please help, i dont know why its overfueling like a bitch by the sound of things?!
