my corsa-c c20let conversion - Page 3

showcorsa · 01-08-2008, 21:03

ive tried 3 relays now m8..so cant be that.. hmm.. i think there mite be a slit in the cps come 2 think of it

showcorsa · 01-08-2008, 21:05

tried 3 different relays m8.. and dunno about the cps

donvaux · 01-08-2008, 21:06

cps??

showcorsa · 01-08-2008, 21:08

crank position sensor..

showcorsa · 01-08-2008, 21:08

do u no any1 whos selling a crank position sensor?

donvaux · 01-08-2008, 21:10

ah right sorry lol, try removing the sensor from the block but leave plugged in and wave a metal screwdriver in front of it while listening to the relay it should click, i'm sure there are some on ebay for sale

c20let? then it can only be a few things. as said, fuel pump relay or crank sensor are main culprits. do you have an ecu light wired in? is it on at all?

ye it is on m8

showcorsa · 02-08-2008, 22:30

put a tester on the crank position tester 2day. the are 3 pins in the plug at the top.tested them with the ignition on and they hav no power is that normal?

showcorsa · 03-08-2008, 11:57

i have put the fuel pump 2 positive and theres petrol coming out wiv the pipe off. but wen i connect it back up there is no fuel getting into the rail

showcorsa · 03-08-2008, 15:24

on the fuel rail!! which 1 is the in and the out?

eggman · 03-08-2008, 15:56

the out from the rail (return) is the pipe at the pressure regulator end left side

showcorsa · 03-08-2008, 16:29

so ive done that right .... hmmm
dunno y it aint working then :S

ok so does the ecu light go out after a few seconds of engine cranking?

if it stays on read off the codes.

does it get a spark at the plugs?

rodgerq

showcorsa · 03-08-2008, 17:49

no it dnt go out m8

showcorsa · 03-08-2008, 17:50

plugs r sparking aswell
will the fuel pump only start working wen its running?

rodgerq · 03-08-2008, 18:06

fuel pump should run when you crank the engine over. check the plugs and see if they are dry.

you say you get fuel to the feed line when you 12v direct feed the pump? are you positive the fuel lines are on the rail the correct way? inlet pipe to right hand side of the rail. did you try and start the engine with a direct feed to the pump?

if you are getting a spark i'd say the crank sensor was fine. next step up the chain would be fuel pump relay as long as you know the wire going from the relay to the pump is fine.

try a direct feed to the pump by bridging the thick red to the thick red/blue on the bottom of the fuel pump relay base. if the pump runs, try and start the engine and see if it starts.

if it starts then i'd say it was your fuel pump relay that was the culprit. if it still doesnt start keep the feed to the pump and press the shraeder valve on the fuel rail and see if fuel squirts out - just jab it quick or it'll cover you and the enigne bay in fuel. if it squirts out then you are getting rail pressure. if the plugs are dry and you are getting rail pressure then its the injectors thats not opening - that can either be an earth issue or a live feed issue(live feed comes from fuel pump relay)

i'd also get the fualt codes read off the ecu and see what they say incase its somethin else but TBH i cant see it - the ecu can pretty much compensate for every sensor being ****ed.

ive tryed bridging it and the pump works.. tryed putting pump 2 a positive wen the fuel connection was off.. fuel went everywhere lol... will hav 2 check the plugs agen tbh m8.. i think they was dry cant remeber now

and the fuel lines are on the right way :S

sound. get the fault codes read off and see what they tell you aswell remember

i havnt got anything 2 plug my reader into m8. isnt there supposed 2 be a 16 pin plug
mines only about 5 pins straight off the loom :S

rodgerq · 03-08-2008, 19:14

you can read the codes using the ecu light. on the LET loom there will be a smallgreen square shaped plug near the ecu. find the brown/yellow wire in that plug and earth it. then turn on the ignition and the ecu light will flash the codes off.

see here for instructions on reading the flashes

http://www.topbuzz.co.uk/info/fault_...ault_codes.htm

its a good article that. have a read through it then see if you can read the codes off.

if you still dont get it, record the sequence on your phone as a video and post it and i'll do it

i havnt got the let ecu wired up 2 the corsa-c dash tho m8.. is there a 16 pin thingy that u can buy 2 plug into it?
got fuel in the rail now m8...
cant start it cus there is oil coming out of the sandwich plate above the oil cartridge

any1 got any spare washers?
