Hello all

A mate of mine has a xr2i and he cant start it from cold if u bump it it will start but when it is warmed up it is fine
some one told me it was the cold start thing??
does any one no wat it is and how much is the part is
thanks RST

 

im not an expert but im sure the xr2i dont hav a cold start valve

 

kk any ideas wat it could be then

 

does it wind over on the starter?

 

yea its turn over and over but just sounds like it anit gettin as much petrol as it needs

 

sounds like it aint pressurising the system properly b4 start up. U know, that buzz the feul pump makes when u turn ignition on. Mite b a relay?

I will c if i can find out

 

thanks 4 that mate

 

If it sounds like the engine is weak on cold starting its worth checking the starter motor. CVH's suffer with starters and its always harder to start a cold engine as nothing has heated up and/or expanded so the engine will be a little tighter.

If it was a fuelling problem or something alike it wouldn't bump start well either.....just a thought

 

A good point but these systems should maintain pressure. The prime is there to ensure a positive re-start but in most cases even without a prime the pressure is sufficient. Don't overlook this though its a good point none the less

 

Thanks mate i will let him no

 

Something else that just popped into my head is these cars have inductive CPS sensors, and it the car is turning over too slow they don't produce sufficient voltage to the ECU, but hence why when u bump start it the car starts. My money is on the starter

 

do u no how much this is and where it is on the car

 

Where what is??

 

inductive CPS sensors,

 

Ah right i see, if u look down the front of the engine u will wee the wiring plug and it sticks through into the gearbox/flywheel. I doubt this is your problem though, if the engine doesnt spin over fast enough the output voltage of the sensor wont be high enough, the faster the CPS reads signals the higher the AC Voltage is across the outputs.

 

ok mate any think else u think it could be

 

Could have something to do with the Ford badge

 

lol kk fair point

 

I suppose it could always be the battery aswell thinking about it.......

 

na coz i tryed a jump pack on it as well

 

sounds like you mite hav 2 get back 2 the basics. have u checked 2 c if its gettin spark at the plugs. pull a plug lead off, stick a spare plug in it and turn the engine over and c if its sparking. try all four. least then u can maybe rule a sparking problem out.

 

It's already been identified the car will run if bump started.....

 

Just spoke 2 me mate and he said this sounds just wat it is doing just not getting as much spark as it needs

do u no how much and where on the car mate cheers RST

 

What for a starter?? I've never bought one funny enough being prone as they are, but as u look down the front of the engine there its right there, u will see the THICK red starter cable running to it. Personally i'd buy a New Ford one and not a re-con, or u might get lucky and get a god second hand one cheap.

Before he spends out though get him to have a battery check done, which is usually free. This will also cause the same problem if the battery is getting weak.

 

lol
kk mate sorry mate lost u 4 a min
im going 2 clean up the wiring on the starter 2day
chaars RST

 

Any luck?

 

lol na i got 2 do it this sat day now i will keep u posted

 

Hello mate
tryed clean them it anit that
but i took one of the spark plugs out and test 4 a spark and there was nun so..... any ideas

 

As i said earlier up, either a lazy starter or a knackered battery. If the engine doesn't spin over fast enough the sensor won't produce adequate signal voltage for the ecu, but when you tow-start it, it does because your not using the battery to start.

If i were you, first things first, battery test, if its fucked, buy a new one and try again, if its ok, try another starter.

 

so u dont think it is the engine wiring loom amp

 

The what????

 

a mechanic said this thing in the middle of the bulkhead which this big plug goes into and he said it is the amp which gives it all the power

 

Not being funny mate but it sounds like that machanic doesn't know what hes on about. Theres 3 things on a plate on the bulkhead:

1. MAP Sensor
2. EDIS4 module
3. CO Potentiometer.

I'm guessing he's talking about the EDIS4, which is what has the basic spark settings in, which it calculates from the CPS. The ECU then takes information from all the other engine sensors and modifies the signal and sends a SAW (Spark Advance Word) to the EDIS4, but if something fails the car will still run from the EDIS4 alone but with compromised performance and economy.

If the car starts, and runs as normal from a tow start, its extremely unlikely to be anything like that. If you understand what im getting at?

 

thanks mate

 

Have you sorted it?

 

not yet it is sitin out side me work he has found out wat it is i will ask him tuesday he just has got 2 get the part

 

ok

 

EDIS4 module
is that the ignition amp module
cos that is wat it is
115 from ford and i can get it 4 90 with trader discount but do u no any one who is breakin a xr2i i could get one off 4 cheap
cheers Mate RST

 

It is the EDIS4 thats very odd

You have PM though
