Sounds like the cold start injector is playing up, try disconnecting it ( its on the side of the plenum chamber). Just pull the plug of it and see what happens, failing that possibly the thermotime switch is at fault Quote Link to comment Share on other sites More sharing options...
kentranger Posted April 3, 2006 Author Share Posted April 3, 2006 unfortunatly it has not got a cold start injector on the side of the plenum. Quote Link to comment Share on other sites More sharing options...
geoffbeaumont Posted April 3, 2006 Share Posted April 3, 2006 unfortunatly it has not got a cold start injector on the side of the plenum. 3.9 would be Hotwire - the cold start injector was part of the older flapper system. 'Fraid I haven't any useful suggestions to add Quote Link to comment Share on other sites More sharing options...
kentranger Posted April 3, 2006 Author Share Posted April 3, 2006 i was afraid this was going to be the case. i am pulling my hair out now lol. its been 2 weeks and i still cant drive my rangerover. the ford escort just aint the same Quote Link to comment Share on other sites More sharing options...
geoffbeaumont Posted April 3, 2006 Share Posted April 3, 2006 Been there - mine was off the road (and not in a good way ) for four month recently after the timing gear went. Bought an old escort off a mate to keep me going. It was reliable and...err...can't think of much else to say about it... Quote Link to comment Share on other sites More sharing options...
kentranger Posted April 3, 2006 Author Share Posted April 3, 2006 its weird going from a car that had 4 litre lump to a car with the same amount of pistons lol. its quick but just lacks the pure power. but then again its a ford. Quote Link to comment Share on other sites More sharing options...
kentranger Posted April 4, 2006 Author Share Posted April 4, 2006 i have just disconnected the lpg wiring from the left bank and it seems the plugs that side arent getting wet where the plugs on the right bank are soaking. so im hopeing that it could be the controller boxes for the injectors. is this possible?

kentranger Posted April 4, 2006 Author Share Posted April 4, 2006 well i disconnected both sides. dried the plugs out put it back together and nothing not even a single bang. oh well i suppose its in the crusher for this 1. Quote Link to comment Share on other sites More sharing options...
Joost Feys Posted April 5, 2006 Share Posted April 5, 2006 Had the same problem, took me 4 weeks and lots of spare parts to find out that you have to put NEW spark plugs in - problem solved. A set of spark plugs is now standard on board equipment Good luck Joost sIIa 88 1967 - RRC 3.9 1992 - RRSport 2.7D 2 weeks old Quote Link to comment Share on other sites More sharing options...
Ivan Posted April 5, 2006 Share Posted April 5, 2006 I had a similar problem on my EFI. Remove the fuse to the fuel pump, turn the engine over until it stops trying to fire or you are sure all of the fuel has been removed from the feed line. Next try starting again but just touch the fuse on and off until it fires, once running put the fuse back permanently. Problem with mine was it was adding extra fuel and would not start. It's been fine ever since. As Joost says, fit a new set of plugs first. Failing that check your electrical connections on the HT side and check you are getting a spark from the coil, a spark at the plugs and fuel from the feed line. If it's got a spark and fuel it should start. HTH Ivan Quote Link to comment Share on other sites More sharing options...
kentranger Posted April 5, 2006 Author Share Posted April 5, 2006 4 weeks ago i replaced everything. i.e the cap. rotor arm leads and plugs. the car is not even aptempting to fire. have checked the plugs for a spark and there is a fairly decent spark there. there is definatly fuel but way too much as when i take the plugs out and turn the engine over i can see the juice squirt out from the bores. i have left the plugs out for a day to dry it out and tried it on the gas but nothing. not even a single bang. i have disconnected the battery as i have heard this will clear any errors the ecu has. fireing order is correct. i have checked to make sure the vacume hose from the fuel regulator is connected and thats fine its not split. even tried easy start and plenty of but nothing. and to top it all the escort is driving me mad. feel very unsafe driving the thing so i might have to invest in a Quote Link to comment Share on other sites More sharing options...

Niall_CSK Posted April 5, 2006 Share Posted April 5, 2006 in a DIESEL! NOOOOOOOOO! It sounds like the injectors themselves from your description of all the work you have done. You can get your existing ones ovehauled & recalibrated, sorry I can't remember the name of the company off hand. The benefit of that over just replacing them is that they will be able to tell you if you have had a problem with the inectors or not. So if not then you can rule that out. Way out thought but not ridiculous is that your camshaft or rockershaft could be so worn that the engine is not breathing properly. I have opened an engine that was struggling with compression on one back to find that the problem was down to a blockage in the oil feed to the rocker on that side only and there were big steps on the rocker shaft. It's surprising just how much hydraulic tappets can cover up. Quote Link to comment Share on other sites More sharing options...
kentranger Posted April 5, 2006 Author Share Posted April 5, 2006 i thought about the injectors but also thought it could be the pressure regulator. or even the ecu unit. i have also replaced the air flow meter for a known working one aswell. i think it may possibly be compression related as it wont fire up on the gas. a friend told me it might be down to bore wash with all the fuel it has had. not sure what bore wash is or how to cure it tho. even tried another set of plugs today and a new king lead but still nothing. are ngk's the better plug as i was told champion double copper would benefit the gas system as they run better at the slightly higher temp? oh and aparently the engine had a complete overhaul at 180000. i knew the guy who owned the car before the guy i bought it from and he said he had the engine sorted. its on 200000 now so im hopeing the rockers and cam are ok.

kentranger Posted April 11, 2006 Author Share Posted April 11, 2006 hello again all. after days of testing i couldnt find much wrong apart from a dodgy injector. so im left scratching my head. just by the off chance of pure frustration i tampered with the ignition timeing a little and it fired up. i could not beleive it. runs well on the gas but has a missfire on petrol. left it running for a while and noticed the cooling system was getting pressurized quite a bit. after letting it cool for a while i took header tank top off and started it up only to find constant bubbles so its now a case of stripping it down and getting the heads off. well started to strip it down when i took the inlet manifold off i noticed a water hold blocked with what looked like a digestive biscuite type stuff. didnt taste it tho to find out lol. got right hand manifold off no probs which i was expecting at least one or two studs to cnap but they didnt. started on the left side and got as far back as the last 4 studs and i gopt 1 rounded off nut on the under side. ( it had to be the 1 i cant get to easily) and thats where i have left it for now. ill go out there in the morning with the hammer and chisel and see if i can sort it out. thanks again for all who have helped. but i feel i have a long way to go yet Quote Link to comment Share on other sites More sharing options...
FITZ Posted April 13, 2006 Share Posted April 13, 2006 I've only just read this thread and I'm sorry to hear you have now found other problems. Your original problem could be one faulty injector. If one injector is faulty and goes down to earth the other three injectors on the same bank will open full bore and dump fuel into the bores. Best of luck let us now how you get on.

kentranger Posted April 22, 2006 Author Share Posted April 22, 2006 hi again all. well managed to get it all apart. sent heads off to the engine center to be skimmed. i noticed there was signs of bad pitting in the block so i rubbed it with as bit of sandpaper round the affected area to check it out and it seems to be only slightly. so i continued to clean up the block. got the shiney new looking heads back and put it all back together again. its running a little rough with very bad idle. ranging from 650 to 2000 just up and down all the time and then it seems to stabalize for a few mins then starts to hunt again. i have tried as much as possible to checxk for air leaks but there dont seem to be any. the bubbling in the header tank has now stopped and the coolant system is no longet undert pressure so thats 1 big weight off my mind. all i need to do is get the old girl running evenly on idle. it is however very sluggish when on the road aswell so i might take it to a garage to be tuned. i have replaced the plugs yet again and it made no difference.

geoffbeaumont Posted April 22, 2006 Share Posted April 22, 2006 Have you checked the ignition timing? If that's okay, have you got a decent spark at all plugs? If you're running a compromise ignition timing for gas and petrol you aren't going to get a particularly stable idle nor the best performance, but it shouldn't be anywhere near that bad!
