I cant start my car! - Saxperience

markvtr06 · 10th March 2009, 14:49

I keep getting my car started and then it messes up again, iv tried loadsa things but im running out of options! my engine managment light wont come on. just the immobiliser light flashing. tried all earthing pionts and a diagnostic check but it came back as not being able to read it?? any1 had similar problems?

markvtr06 · 10th March 2009, 15:09

also when the cars running the engine managment light flashes on n cuts out the engine only for it to bump itself!

i know when the cars gonna start because the engine managment light comes on when the ignitions switched on but when it doesnt it wont start. could this be a dodgy ecu?

Does sound a bit odd.

Get it on the diagnostic machine mate.

markvtr06 · 10th March 2009, 15:18

iv tried it, the guy at the garage said it wouldnt read the ecu, i fink its a corroded wire maybe?
i have bin through it all and checked all of the fuses but it looks like a loose/broken wire because i moved them about whilst refitting my battery and the car worked again for a bit?

Check your main earth from the battery then. Take it off, sand down the metal on the connections to the bodywork and the battery.

Can't see why it would kick up the immobiliser light though.

markvtr06 · 10th March 2009, 15:26

tried it, also tried 2 other earth piont sanded them down to bare metal and then wd40'd them both. also tested the 12v live wires with a ohm meter[not sure if thats its name] but the wires to the ecu and the black box beneith it both have power?

Does your car have the transponder in the key or a keypad?

markvtr06 · 10th March 2009, 15:35

transponder key, iv already treid 2 brand new areials for it as i know there dodgy but as soon as the engine managment light comes on, the immobilisers goes off and it starts, its just getting the engine managment light to come on in the first place when i switch the ignition on.

Do you have jump leads mate?

markvtr06 · 10th March 2009, 15:43

i mite have in the shed, how come?

Liam · 10th March 2009, 15:48

Stick on end on the engine lift hoop on the front of the engine and then stick they other end on the negative pole of the battery and try and start it. Just the black cable on the jump leads are needed. Try this and if the car starts its the earth behind the battery.

markvtr06 · 10th March 2009, 15:51

ok will do now, il report back inamin

Liam · 10th March 2009, 15:54

Liam · 10th March 2009, 16:03

Yer i have 2 spare starter relays ones new ones not but it works. If you wanna buy one from me. Worth a shot. There handy to have.

markvtr06 · 10th March 2009, 16:06

i got a citreon garage down the raod il nip in tommorow and buy 1, thank for the offer, it just seems that theres no power at all to the engine managemant even tho iv tested the power cables!

Liam · 10th March 2009, 16:13

Just a heads up, i needed one and had to wait, i can post it first class now if you want one and i can assure you it will be cheaper. £10 delivered and youll have it thursday.

Liam · 10th March 2009, 16:14

Also does it try and turn over? Could well be the crank sensor. I also have one of those and for your year of car too.

markvtr06 · 10th March 2009, 16:16

yh it trys to turn over but doesnt start, i know when the cars gona start because the engine light comes on but if it doesnt do that then it wont start, its like the ecu isnt attacted somtimes

Liam · 10th March 2009, 16:18

Well try the crank sensor. They will allow the car to turn over, but they cut the spark.
