View Full Version : not starting first time xe
hi
just wondering where to start solving my starting problems, sometimes it will start first time others it will take 3-4 tries, where should i start to look thanks
Plugs
leads
distributor
crank sensor
fuel?

Most liely ignition related or crank sensor. Try a new genuine rotor arm & see if you can flash up any fault codes. Crank sensor will be at fault if the engine isnt running however.
craig, mine was hesitating to start today. almost like a bad earth if you get me but there all fine.
what would cause this?
Plugs
leads
distributor
crank sensor
fuel?
is there a way to test the ht leads as i dont really want to change them as they are coloured
You could measure the resistance with a multimeter, most leads are about 1k Ohms.
Different readings for different lengths

sounds like a fault crank sensor to me :)

was yours warm ???
no from cold browney
it starts but hesitates at 1st and flicks like its got an earth fault. but there all fine

You checked the earth on the fuel rail, does sound like a crank sensor fault aswel :)
There piss cheap on ebay now :)
yeh i have an earth going from the alt bracket to fuel rail, the one on left hand side of fuel rail attached. then the 2 on the right hand side.
also one on the box to the chassis leg.
was it a 1.0 originally?
yes was a 1.0 will it most likely be the crank sensor than? where abouts is it and how do i change it thanks alot for the help
open the bonnet facing the car, bottom left hand side of the engine. just under the thermostat ish
held on by 1 x 8mm bolt iirc

Where have you got your switched live from?
As the switched live for the coil, is around 6/8v on a 1.0:thumb:
Try running a wire to the + switched, from the purple on the wiper motor. This is a switched 12v supply.
Same as the reverse light, but has a bigger feeder wire:thumb:
crank sensor is a 10mm btw bud...

So what did I say to do:roll:
"Put it on a switched feed":wtf:
right i have changed the crank sensor, but now it wont start at all, put the old crank sensor back in but still wont start. just keeps turning over
put volt meter across the coil both sides read 12v, one side has a red wire (the closes to the headlights) and the other side has 2 cables at it, a blue one, (both the blue and the red cables come from a plug connector next to the coil) and another blue with a black line on it, so thinking that it has had a proper switched live ran in any other ideas?

yeah, from the wiper motor, go re-read your post. :roll: :roll:

Ok so it's not the coil wiring then, if you have 12v going in. do you have spark?
sorted why it wouldnt start the earth strap was loose stillnot starting first time though but its a start
this is my old car from about 3 years ago, it had the same problem then, it also had a misfire every now and again,it started fine when it was hot , i changed every part on the car and it never cured it, i was sure it was something to do with the fuel pump and boot mounted tank, i even brought a new ecu, airflow meter, wernt cheap! it was asif it was running out of fuel, what set up is it now??:confused: it was the reason i sold it:( :(
no longer has the boot mounted tank pal still got it but it doesnt hold enough fuel, it didnt bother me to much, just took about three times then it started but now its not doing anything just turning over and not starting up
was hopeing it was an easy fix but not looking that way lol
i no it has the fuel lines still running through the car but going to change them to braided ones and run them back underneath,
has it still got the pump indside the car? and im pretty sure if you bump start it, it goes, i sold it to a guy in manchester who brought knowing it had that problem, it started fine first thing in the morning but after that it was doing the same as it is now. 3 years on and it seem to still have the problem, hope you find it:(
what year and type of xe is it?
not a clue as i have only just bought it, is there a way i can find out?

no hasnt got the pump inside anymore
engine number, is it a 20xe or c20xe? also pics of the bay mate.
was told its a c20xe

anything percific in the engine bay?

when yiou said about the black wire to the coil, usually dizzy xe's have a blue and a red from the amp and thats it. the coil is fully fed from the amp. its possible the second black is interefering with it. got any close up coil pics?

Them leads look like the chingwah specials?
Try a set of beru leads:thumb (leads@thumb):
the leads are bk racing 10mm
few pics of the coil

im sure mine doesnt have that extra blue wire on the coil...
** runs outside to look
not a clue what that extra wire is for mate

try the connection on the 2 pin plug on the thermostat housing it tells the ecu the engine temperature so it no's how much fuel to send when starting.
and use standard h.t leads.

right will change the leads to some standard ones,
is the thermostat housing the one just above the crank sensor , below the coolant pipe on lhs?
shall i just remake the connections on it and maybe thats my problem thanks
also found a note telling me what all the wires do in the car, the "unknown" blue/black says coil/rev counter
do you think it might have something to do with it?

yeah its above the cs sensor there should be another single wire next to it for the temp gauge. just make sure its got a good clean connection and that the clip is there to. also check for air leaks after the air flow meter. split hoses or gaskets on the throttle bodie and inlet manifold
