2328.0. "escort with hot starting problem" by RDGENG::CLAYTON () Wed Oct 12 1994 14:00

Hi 
    I wonder if any you guy's seen this before ?


    problem:  1986 Escort 1.3l ohv engine with vv carb "varible venturi" 
       
    After a long run the car refuses to restart after being parked for five 
    minutes maybe even half an hour. I know the engines ok. no fuel or spark
    problem. its had a recent service. Compression test is fine timing is 
     fine, mixture is fine. I have an idear it might be fuel vapourization
    but have no previous experence with this problem on any other car.

    ps.  the car restarts fine after about an hour without changing or fixing 
    
    anything ?

    Well I'm surprised you haven't had any replies yet (where are all you
    armchair mechanics!).
    
    I'll have a stab anyway.
    
    First off these are symtoms of vapourised petrol so you could be on the 
    right track. Does the car have automatic choke ? Try putting your foot
    hard down on the accelerator, this may pump some petrol into the carb.
    
    Does the engine bay smell of petrol after a few failed attempts to
    start ? If so this would indicate that its flooded in which case too
    much fuel is getting through.
    
    I've just done some work on a car with fuels probs that turned out to
    be a blocked fuel filter.
    
    Has this always been a problem or just since the service ? Maybe if you
    supply more history of the problem you'll get some more ideas.

    My dad had a same problem. Sure enough, automatic choke was knackered.
    I'd say it's almost definately the fueling which affects this hot
    starting problem. There are other causes, I'm sure, but it's your best
    bet. Maybe when it was serviced somebody did something wrong - no-ones
    perfect, y'know, even Ford machanics ;-)
    
    Hope you get it sorted.

2328.3Auto ChokeBLKPUD::ROWEMFrank Gamballi's Trousers!Wed Oct 12 1994 18:185
    I used to have escort cvh's of that sort of age when with a previous
    company and several had this prob which was due to the autochoke.
    I don't know what they did to fix it, but any ford garage should
    be familiar with it.....

    Fix : replace it, or put in a manual choke.
2328.5yep 4 sureWARFUT::HERONDThu Oct 13 1994 11:505
    Yes the fix is to replace the choke with a manual one,
    
    Cost aproxx �35.00 about 8 years ago.
    
    I must say I was glad to see the back of that car though ??
2328.6RICH Mixture is at fault OKESSB::DOODYThu Oct 13 1994 18:183
    rich mixture + COLD engine = START
       "         + HOT  "      = WONT START
    
2328.7thanksRDGENG::CLAYTONFri Oct 14 1994 12:548
The escort still has this problem.   it has an manual choke on the carb 
and the mixture was set up at the mot  station " I should think the co 
is quite low on an  excort 1.3 non cvh.  I think I will end up getting 
a replacement carb for it.



                 Thanks Richard

    CO content rarely should differ between engines, no matter what make or
    capacity. Having said that, it doesn't mean there's a set value for
    every 1.3 x-flow Escort engine, because of course every engine is never
    perfect. Plus some engines will be appreciably different (ie. diesels,
    funny-car V8's running on alchohol, tuned engines, etc....!).
    
    A new carb will probably sort this problem out, or else (if you fancy
    doing it) a thorough re-build of the existing one :-l
    
    Have fun!

    It definetely sounds like the carb.I had an Escort Ghia 1.6(87)and it
    had the same symptoms,it would run okay then splutter a bit,then
    sometimes break down in transit.It also wouldn't start,after running
    perfectly just before I parked it.
    I took it along to get 'tuned' and they found some crap in the jets of
    the carb.,they replaced them then it seemed alright.
    It broke down about 1 mile away from the 'John Wayne Tuning centre'.
    Anyway Mr RAC came and he said my coil was the culprit,so I borrowed a
    new one to see if it would cure the problem.
    It didn't,so I took of the carb and carried out a rebuild and clean,and
    it ran brillianty after that.
    Sorry this was a bit long winded but it might save you shelling out
    cash on a new(second hand-hard to find)carb.
2328.10Perhaps the Condenser?ROCKS::ARCHERGWhat's another word for Thesaurus?Wed Nov 02 1994 16:0124
    
    
    Hello,
    
    Well what I know about cars you could write on a pin head!
    
    But...(and sorry if I'm rat hole-ing).. I had an old Marina once.
    It was my first car after I passed my test.
    
    It had this annoying problem of not startng when hot. Bloody annoying
    when you've driven for hours, pull into a petrol station and after
    filling up find the thing won't start!.
    
    After much mucking about with carbs and fuel and fuel pumps I found the
    problem was the Condenser. 
    
    Don't know if your Escort has "electronic points" or not, but the cost
    of a condenser is much cheaper than a carb..!! 
    
    You might even be able to ..er um.."accquire" one from a scrap yard!
    
    Regards,

2328.11Broke Choke?JANSKI::JOCONNORSomebody else did it and ran away.Wed Nov 02 1994 16:075
    It is possible that the choke mech is broken/stiff. So that even with
    the choke knob in, the butterfly is still closed.

2328.12old Ford Carb ?WOTVAX::STONEGTemperature Drop in Downtime Winterland....Thu Nov 03 1994 15:0813
    
    ...if this is the standard type of carb fitted to Fords, with the
    heated manifold, it could just be fuel vapourisation (at least I think
    that's what it's called). I had a similar problem with an old Cortina
    once, arrived at a Petrol station on the day I bought it only to find
    it wouldn't start after filling up ! luckily the attendant there had
    seen the problem before, you just floor the accelerator and turn the
    key - worked every time.

    BTW, if this doesn;t work my money would be on the condenser...
