Hi there guy i was wondering if you s can give me a hand to get my cossie back on the road so i can play? heres goes i was mucking around with my mate and then gunned it away from a standing start after it it was back fireing and running spluteryi then found out that i had broken the map sensor.I have got another one on it(3 bar same as the other one)put that on the it will not give me a spark.I have changed the coil and had no joyany sujestions guys?really wanting to go out and play
thanks for taking time to read this

 

faulty 3bar you've put on? try a different one.....

Or put you old one back in to be 100% sure its that which is the problem.

Dan

 

yeah i tried that the one i fitted is of my 3 door was running perfect i put the old one back on but still no joyanymore sujestions please)do they have anything to do with the spark?

 

what I meant was put your old one back on and see if you get a spark then....It could be a completely different problem un-related to the map sensor being changed.

So put the old map on car, check for spark....then you know 100% your not getting spark becasue you've changed map for different one.

Dan

 

will try it 2moz and will post back
cheeRS

 

R u sure it's the MAP sensor?????

 

does the fuel pump prime when you turn ignition on then switch off after lets say 5+ secs?

are you getting a ignition live to the coil (you can check this with a multi-meter)

is you Phase sensor connector plugged in or maybe faulty, check wiring and connectors, also do this for the CPS as well and is that gapped correctly, also check your 2 relays & fues on your ECU loom this may be faulty or blown?
If so the fuel pump won't prime and neither will the ECU fire up!

And lastly why where you gunning it if it was missing & spluttering this will cause damage driving it like that

 

I've read that as it went spluttery after the launch m8.

 

YEAH THE FEUL PUMP IS GOING I KNOW WHAT YOU MEAN BUY THAT ITS GETTING PETROL THROUGH BUT NO SPARK WILL CHECK THEM TOMMOROW THANKS FOR HELPING WILL LET YOU KNOW WHAT HAPPENS I GOT TOLD THAT IF IT WAS THE MAP SENSOR (FAULTY)IT WOULD STILL RUN BUT SPLUTTERY AND I TOOK THE ONE OFF MY 3 DOOR AND STILL NO DIFFRENCE I CHANGED THE COIL ASWELL BUT STILL NO JOYITS TURNING OVER BUT NO SPARKING IF YOU KNOW WHAT I MEAN (NOT RUNNING BUT WINDING OVER WHEN TURN OF KEY)HONESTLY THANKS VERY MUCH FOR TAKING TIME TO HELP ME WILL WB CHEERS GUYS

 

So you changed the map sensor back to the one you had before and still no spark? If thats the case then it's not the map sensor thats faulty mate....It must be an unrelated issue causing the lack of spark.

As mentioned above...check the phase sensor in the dizzy as these fuck up after a while and make sure the crank sensor is gapped properly and working right.

Cheers
Dan

 

right guys i check for a spark and its getting it (will need to check plugs again but they have not been on longer than 4 weeks ish)getting petrol through aswell well and it still will not startreally puzzeld now i have the spark plugs out after it happened and they looked fine anymore sujestions once again cheeRS for helping me really appreciate spending your own time to help me

 

had the same sort of thing on mine it was the crank sensor worth a try only £23 off matt lewis

 

so u have a spark, and fuel, and its cranking.... but not firing?

failed tdc sensor on the front bottom pulley, or its loose or the connector has got muck in it.

 

does it still spark if the crank sensor is not working?because on a rs turbo the dont spark if the crank sensor is not working any susjestions have crank sensor not will give it a try on if it does still spark if broke cheeRS

 

yeah mine was still sparking but not a the right time hence it would not run got to be worth a try might be worth replacing the phase sensor as well as they can give problems

 

Hi Mate Does The Engine Turn Over Faster Than Usual? If So Could Be Worth Doing A Cylinder Compression Test.

 

check the basics first such as the dizzy cap & rotor arm. had it a couple of times on an old rst when launching it, the dizzy was slightly worn & it broke the locating peg off the rotor arm, started backfiring and then wouldn't run

 

is it fireing in the right order.

if you have a spare ecu try that.

as they sometimes fry.

and check the loom

 

hi buddy i have done all them things away to change the crank sensor as MATT BAXTER says some one else told me to try that aswell the car was running outside my house(but splutry and it was back firing so iam 99% sure that the compression is fine thanks alot guys really appreciate you taking time to help me

 

i'll wager you a tea, white, no sugar on it being the tdc crank sensor - OR its connecter.
