All was fine then last night i noticed the car felt a little slower than usual.Seems boost is down and it was cutting out occasionly when commin on to boost any ideas???

 

maybe an engine sensor going down

 

How do i check um ?do u think map senser?

 

i would think more like the air/engine temp sensor,,

is it driving ok today?

can measure the resistance at the ecu connector

does it idle normal?

 

Idles fine i have had probs with the charge temp sender but it all was reading fine on my sex moniter.I havent tried it today it felt very flat tho last night not pulling hard at all

 

i might of sucked the wrong tit then

 

 

Check on SECS monitor the following...

1) The MAP readings are near zero (+/-0.5 psi) when the engine isnt running.

2) Check the coolant temperature reads 80-95 C when fully warmed up.

3) Check the throttle readings are 0 to 100% for the full travel of the pedal.

4) Check the battery voltage is above 12.7 volts when the engine is idling.


And a few questions ....

Does the car rev above 4000 rpm when warmed up ?

Does the car when it cuts out, cut out completely then recover or does it
surge (jerky feeling) ?

 

WOW simon u are helping me

Right
1yes im sure it was
2yup all fine on water temps
3i think it was reading right il check in a second but yes im sure it was cool
4yes battery voltage is high normally 13.9 when running

Yes im sure itdid rev past 4 k when the first cut out happend it was at about 4kIt wasent cutting every time but felt gutless When the car cuts revs drop off and its ok to cruise car doesent stall no kangaarooing well it might if i just left me foot down

 

Could possibly be a fuelling problem.
My advice is do not drive it hard until it is checked by a competant person.
Cossie engine rebuilds are not cheap.

Next time it happens watch the rev counter.
Does it still read correctly or does the reading drop like a stone when
the problem happens?

Its hard to diagnose problems like this over the internet !

HTH

 

It drops like a stone

 

Sounds like the crank position sensor, phase sensor or ignition amplifier
are on the way out.

Replace them in that order !!

 

Thank u simon unexpected help there and appreciated

 

sounds like top advice too me

 

Right revival time she is still doing this she seems really shit to rev real slow.She also still cuts compleatly when comming on boost.Parts i have changed are crank senser phase senser air charge senser ive cleaned the ign module but not replaced yet any one got any good ideas where to look next??

 

Sounds silly but plugs could be fooked, so when coming on boost its dieing?

 

Nige, If you want to drive it down to me over the weekend, I will give it a thorough check over for you.

 

top stuff simon

 

Ah i missed the rest of these posts, very nice offer simon but the car was off the road the wiring for the fuel pump is a little fooked.Today is the day tho ryan is o route now to sort her out lol i hope Today we will be gaping the phase senser checkin gap on crank position sortin fuel pump wiringtrying a new tps and a new ignition amp thingy.Wish us luck cos i think we willl need it lol

 

OK ryan forgot all the stuff The phase senser wasent gapped right we gapped it and it runs ruff I think ive had enuf of this car and her fucking problems

 

chill maan, it aint nothin too serious!
jus a matter of finding the right wire (the one thats fukked)

might take time, but its worth it !

 

Right she is running again thank god, seems it was ither the map senser or the ignition amp.Car still runs shit tho throttle is very fluffy and revs are slow to pick up also she isnt boosting quite as she was.but when i fitted the phase senser i didnt gap it lol and it wore away at the dizy metel bits that phase senser reads off all gaped now but dont seem right , stu said it would not effect it tho so im miffed
