hi guys,
my car for ages now has had its own mind on when it would like to start!!!
9/10 times it is perfectly fine, then on the 1 occasion it doesnt; all it will do is turn over!!
this is the weird part though.... sometimes if you give it 5 mins it will start fine, others you have to leave it for hours, BUT; if you bump it down the road IT WILL start and run fine, and even if you try to bump it and dont quite manage it - turn the key and the bloody thing starts anyway!!!haha

I also gave it to Paul at Zen recently to see if he could get it sorted for me, but would you know it - for the whole week he had it there it only went and started everytime!!!!!
So PLEASE... someone........ ANYONE.......

surely out there somwhere is a God who can help me with this problem???...

Crank or cam sensor knack'd? If they are subjected to transient overheating, for, example, then they can lead to non-starts when too hot.

Jason Plato, coincidentally had this happen a couple of BTCC meets ago, as he was riding the clutch on the warm-up lap to try to make the clutch less of an "on-off switch". After much head-scratching by all involved, Chevrolet eventually sussed what the cause was, and had to contrive a little fan cooling system for the crank sensor, so as to remedially get round the issue...

 

What about an earth to the starter itself?


Steve

 

Ahhh, good call by The Gimp

I reckon it is that ^^^

 

Was supposed to say starter. Not start. Not enough coffee yet. lol


Steve

 

Well, your gob is impeded by that mask, after all...

 

If the starter wasn't earthed (through the strap bolted to the bellhousing) then surely the car wouldn't crank over?

I had a car with a similar fault recently - turned out to be the ignition amp breaking down, causing the coilpacks to have an intermittanly weak spark, making the car hard to start.

As mentioned above, also check cam/crank sensors

 

Hi everyone,
thank you to everyone that has posted so far....

in reply to you all - yes the cam/crank sensor was mentioned to me IF it was only happening on hot starts (which wasnt the case all the time, even 1st thing in the morning it happened too).
also the crank sensor is ok as i am getting a reading on my apexi when all it will do is turn over (paul at zen told me that one!!ha), so that has left me thinking maybe just to change the cam sensor anyway i supose - cant do any harm thats for sure!!

Fiestaboy could you explain what you said about the coilpack bit still apply to me... my coilpack isnt actually on top of the engine as it is a v2/3 sti???

many thanks again everyone...

 

Ignition Amp is located on the back of the bracket bolted to the Driver's side strut (front of the bracket has BCS, MAP sensor etc bolted to it)

 

ive had the same fault on other make vehicles and it has turned out to be a temp sensor. by not giving the right temp causes the car to run too rich/weak whaich causes bad starting. hope this helps

 

i will certainly get both those things looked into thanks guys (marcbates85 & fiestaboy)...

its kinda embarrasing having to push my car when it bloody happens i can tell ya - especially when she looks as good as she does!!!LOL



Anyone else out there who had had this before?????.....

 

Anyone else with any ideas please????


all opinions and knowledge very welcome...

 

Did you not got it resolved mate?


Steve

 

Actually mate im not too sure....

i have replaced cam sensor + ignition amp yes, but it has been off the road since having them changed whilst i have fitted -
my new bc coilovers,
new P1 bumper(inc fogs and splitter) freshly sprayed in WR1 ice blue,
cobra buckets,
nearly complete flocked interior,
new momo handbrake, gear **** and pedals,
short shifter,
and the brake calipers are cleaned up, painted and refitted!!!LoL (yes my mrs is now asking why i havent booked a holiday for this year yet!!!hehe)

Should get her back at the end of the week though - CANT WAIT!!!!!!Woooo-hooooo!!!!


thanks for the interest my friend

 

After fitting all that, I bet it won't start!

JohnD

 

Ha ha - yeh thanks for that mr JohnD!!!!!...

i hope your knock link doesnt suddenly hit the red today too!!!

In all fairness i would at least get to have a little drive.... its usually when i pull up at the petrol station and seem to have like 3 cars waiting behind me that she wont start!!!lol


we shall see.............

 

Or at the school fetching my little un and all the yummy mummys are walking past!!!!HaHa
