PeteMck Posted April 19, 2014 Author Share Posted April 19, 2014 ok, TPS sorted now. still not started but least we are making progress. Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted April 19, 2014 Share Posted April 19, 2014 Ok. ..what's closed and high values. .. What's happening when you try to start ?? Quote Link to comment Share on other sites More sharing options...
PeteMck Posted April 20, 2014 Author Share Posted April 20, 2014 Ok. So the engine was almost starting. Would catch several times and for a split second you would think it had started but no joy. Took all the spark plugs out to look at them and there is a fair amount of oil getting into the cylinders. So the plan of action is to pull the engine out strip it down and replace piston rings, bearing shells and everything while I'm doing it and try and identify why there is all this oil in there. At the end of the day if it's that that is causing the problems or not there is enough oil on the tips of the plugs that something is definitely not right. They are pretty cover after a few cranks. Also noticed a build up of quite a lot oil round the butterfly valve in the plenum since trying to start it. Is this normal? Final question, on the bottom of the plenum housing there is the de-icer, one pipe comes out the block where should the other outlet be run to?

PeteMck Posted April 20, 2014 Author Share Posted April 20, 2014 Closed value was around 20 and high was up around 250 maybe just under. Also how much harder will it make it to start without the pmw valve? Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted April 20, 2014 Share Posted April 20, 2014 ^^Values spot on well done ! Without PWM control it will DEFINATELY start, before I did this one mine I would sit in it, press pedal 1" or so down and crank, when it fired just keep the revs going. Unsure that stripping and re-ringing is the route to go....You had one issue / now fixed there may well be another. I would far rather you got the engine running and then decided it it neds a rering than this way around, you could re ring it and still not have it running. So few things .... When you turn on the ignition - does the fuel pump prime for a few seconds - and then cut out ? If you open Mehatune with ignition on, which guages show what values ? Have you connect the MAP Pipe to the engine and the ECU and if so to where exacly on the engine ? how old are the plugs and what type ? If you remove plug and crank engine with plug on block does it give off a big F O Spark ? couple of pics from around the engine bay may prove useful too Report back Nige Quote Link to comment Share on other sites More sharing options...
PeteMck Posted April 20, 2014 Author Share Posted April 20, 2014 Ok. Pump primes fine and cuts out after 2secs. Plugs are brand new Bosch. Map pipe is connected and is between manifold and fuel pressure regulator. Tested plugs and leads and they all spark. Wouldn't say it was big F/O but it's a reasonable spark. I know it's fuelling when cranking as well. also it blows back through the plenum sometimes. :s. Tried using a bit of easy start and it turned the air inlet pipe into a flame thrower :s Quote Link to comment Share on other sites More sharing options...
PeteMck Posted April 20, 2014 Author Share Posted April 20, 2014 The thing with this engine is I don't no for sure that it actually ran before. (That would have made life to simple) Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted April 20, 2014 Share Posted April 20, 2014 ^ LOL it would help !Pics would be good, can you explain bit more re the MAP pipe "between manifold and fuel pressure regulator" and some pics maybe ??? Quote Link to comment Share on other sites More sharing options...
PeteMck Posted April 20, 2014 Author Share Posted April 20, 2014 The little pipe which comes off the plenum sorry to the regulator have put a t piece in that. Would take pics but 45miles from the vehicle at the moment. Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted April 20, 2014 Share Posted April 20, 2014 If you mean the little pipe that sticks up just inside where the butterfly is thats not good..... doesn't give a good vac reading, but agfain prob not bad enough to stop it running What Plenum unit are yyou using 3.9 / 4.6 ? Quote Link to comment Share on other sites More sharing options...
PeteMck Posted April 20, 2014 Author Share Posted April 20, 2014 Ok the little pipe is the one off there. Plenum is the 4.6. Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted April 20, 2014 Share Posted April 20, 2014 where does that pipe go on a 4.6 engine can't remember !!!!!!!!!!!!!! Quote Link to comment Share on other sites More sharing options...
PeteMck Posted April 20, 2014 Author Share Posted April 20, 2014 It goes into the plenum Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted April 20, 2014 Share Posted April 20, 2014 And thats whats puzzling me.....these 4.6 plenums don';t have the stepper unit / pipes etc so confused, without a good suck on this pipe you will have f all advance to help it run.. can you be more specific / pictures ?Nige Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted April 20, 2014 Share Posted April 20, 2014 Flame thrower out the inlet = you have your spark timing or plug leads wrong. End of story really, unless there is something severely amiss mechanically. Have you dried the plugs (heated) and re-fitted? Oil could be from someone oiling the bores pre-storage.

PeteMck Posted April 20, 2014 Author Share Posted April 20, 2014 Can't do pics unless someone else on here can supply one. It just bends over and pushes onto a small outlet from the silver plate for want of a better word the plenum bolts to of that makes sense. Could the advance be causing this spark timing issue.

Bowie69 Posted April 20, 2014 Share Posted April 20, 2014 Trumpet base, yes that'll be fine. And yes, too advanced timing could do that. Quote Link to comment Share on other sites More sharing options...
PeteMck Posted April 20, 2014 Author Share Posted April 20, 2014 Is that likely to be the trigger wheel causing that? Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted April 20, 2014 Share Posted April 20, 2014 Easily....trigger wheels out are often cause of no starties. So describe your trigger wheel positioning .... Quote Link to comment Share on other sites More sharing options...
PeteMck Posted April 21, 2014 Author Share Posted April 21, 2014 the sensor is 5 teeth behind the gap. Worked out tdc by sticking a bolt in the spark plug hole and seeing where the point it was pushed up the most. If that makes sense. :s Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted April 21, 2014 Share Posted April 21, 2014 Ah....but there are 2 positions where piston is at the top....tdc= correct....and exhaust stroke = 180 degrees out. .. Shove engine at tdc then remove passenger rocker cover see if both valves are closed...on one not... Take pics of trigger wheel whilst you at it !! 180 is a very common simple error Quote Link to comment Share on other sites More sharing options...
Cynic-al Posted April 21, 2014 Share Posted April 21, 2014 Thought we had already done that one Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted April 21, 2014 Share Posted April 21, 2014 From the front of the car, looking at the engine, which is #1 to you? Then you need to get photos somehow. Quote Link to comment Share on other sites More sharing options...

Take pics of trigger wheel whilst you at it !! 180 is a very common simple error Only on a distributor Nige! EIDS won't care about 180 degrees out. I must confess I thought exactly the same as Bowie 69 - plug leads in the wrong order or timing wrong. Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted April 21, 2014 Share Posted April 21, 2014 the sensor is 5 teeth behind the gap. ...... er.... Looking at the front of the engine Engine at TDC gap should have past the VR sensor (clockwise) and gone round clockwise until the VR sensor is smack bang cental on the 5th tooth ??? behind to me says "on the 5th tooth anticlockwise of the Gap) should be "After" ie on the 5th tooth passing the vr after the gap has gone past in clockwise direction ???
