loss of power and throttle

[mikeylove]

right guys i have a problem, i was driving the car quite hard just before i went on holidays and all of a sudden i lost power, the engine was still running but no acceleration or throttle, i have checked today and its not the cambelt, any ideas of what it can be!!!

cheers guys

throttle cable snapped?

 

[GT_Neil]

whats tick over like?

were you running a stock car?

 

[mikeylove]

the car wont start up but the car does turn over, its not the throttle cable, thinking maybe the fuel pump!!!

 

[Neal Gt]

yeah mate could well be, turn the ign on and c if you can hear the pump working, if not check geting lives e.t.c to the pump, if pump working check your getting fuel up to the rail if not pump might not be working prob,

just saying, abit wired if it was runnig when you lost the power and now its not.

 

[mikeylove]

yeah it is weird but i have been told the engine would run on no fuel for a very short period

 

[Adam_Glanza]

crank position sensor

fuel pump relay

 

[mikeylove]

im kind of guessing its the fuel related because all the electrical and mechanics seem fine, and there was no det noise or engine failure noise when it happened

 

[Adam_Glanza]

if its the fuel pump relay you wouldnt be getting any fuel at all i doubt.

check the cps sensor as i said, if its not sensing the crack turning then it wont fire.

pop the end of the fuel return hose and run and length of pipe into a petrol can. crank the car over and see if any petrol comes out.

also doing a diag test might give you an idea of the problem

see here for info on how to do it

As already said above, check for engine fault codes.

I would look at the knock sensor, its possible its blown if you were giving it some beans when the engine cut out.

 

[mikeylove]

the engine didn't actually cut out i just lost throttle and power

 

[ragz]

map sensor

av you done a diagnostic test yet

and if so what codes u get

 

[mikeylove]

right i have got the car running the efi fuse had blown, i changed it and it blew straight away, changed it to a 30amp fuse and for now the car seems fine but there is an obvious issue there somewhere, just got to try and work it out now!!!

any ideas

 

[Nwimie]

a short in one of the fuel pump wires ? i would have guessed its a wiring fault if it keeps blowing the fuse. im just clutching at straws

 

[mikeylove]

yeah i think your right, def a short just have to find it now!!!
