Ive done the finishing touches to my conversion today. The car started fine. Then i turned it off, went to turn it back on and nothing. It tries to turn over but just wont start. The key light doesnt flash, but the ECU light does come on and wont go off. My mates has a vts and his ecu light doesnt come on at all when trying to start the car. Any suggestions? Any at all.

reset the ecu?
turn iginition on and take battery off.

How long for mate?

10 mins, take battery off first then turn key twice to igition on. :y:

Oh right ok. Ill Give that a shot. My ECU isnt connected atm nor is my battery. If stick the key in, turn twice then connect the ecu and battery will this have the same effect?

Does the immobiliser light come on?

plug the ecu u and leave battery connected. and try turn the car over. as like your trying to start it.
It wont start like you've said.
Then disconnect the battery, and turn igition and wait :y:

The ecu needs to know what the problem is and when you reset it it'll discard it and hopefully start up :y:

Does the immobiliser light come on?

Nope, i have a really bad feeling about this one :(

Liam

16th February 2009, 16:24

Just wondering, if the ECU has had it, will it still attempt to start? Or will it do nothing?

raunchz

16th February 2009, 16:31

Nope, i have a really bad feeling about this one :(

Have you changed anything at all since starting it?

Liam

16th February 2009, 16:34

Have you changed anything at all since starting it?

No, nothing at all. It starting idling a bit high, but my mate said its just mapping itself (what ever that means) then i turned it off a few mins later, now it wont start. The fuel pump primes and everything, but it just wont start.

raunchz

16th February 2009, 16:56

maybe press the fuel cut off switch, could have pressed it? Fuel pump shouldn't prime, but worth a try.

I'll give it a thought on my drive home from work.

Its defo fueling, i took the fuel line off to check. Its weird though.

Bump it up

how long have u been running the started motor over for each time? Try keep turning it over for 10 secs say.

Liam

Um maybe 5 seconds. Scared of burning the starter out though.

Olly

16th February 2009, 19:27

tried the plugs on the ecu see if there in correctly, see if any wired have become dislodged.

have you disconnected the immobiliser?

Liam

16th February 2009, 19:30

Ive checked plugs i can see. I will change the spark plugs in the morning. Dunno what would cause the engine management light to turn on though :S

williamsvts

16th February 2009, 19:33

immobiliser disconnected? if not you will have locked the ecu.
or you havent connected something properly.

Liam

16th February 2009, 19:38

have you disconnected the immobiliser?

Do you mean the small black transponder box under the dash?

Liam

16th February 2009, 20:00

immobiliser disconnected? if not you will have locked the ecu.

ECU was never unlocked. But that said its not the transponder light thats comes up on the dash. The ECU light comes up. What sensors should i look for?

Olly

16th February 2009, 20:19

u using the keys from the vts then?

Liam

16th February 2009, 20:23

u using the keys from the vts then?

No, i have the code from the VTS on my spare key. Well it was from a GTi

Liam

16th February 2009, 21:03

Would it be the crank sensor by any chance? I put a second hand one on. But would this cause the engine to not start at all? :S

williamsvts

16th February 2009, 21:10

should still try and start. and starter not even turning?

Liam

16th February 2009, 21:12

It wants to start its turning over. It just wont fire if you know what i mean. Its fueling and everything. I really tries to start.

16th February 2009, 21:12

Could it be flooding when you try and start it - ad you've blocked off the return line? I've never seen a vts with the return line blocked so can't say for sure, would be an option?

raunchz

16th February 2009, 21:14

what bar fpr you have on your tank? What fpr do vtr's have?

My mate had his block until the other day. Ran it for months, but i dunno, you defo know more than i do. But all i can really do is unplug the return line and let it go into a bucket to see :S dunno though.

I'm not sure, just thinking out loud.

If it has fuel, and it has spark then it must be a timing problem (crank position sensor) ?

williamsvts

16th February 2009, 21:18

vtrs have 3.5 bar, vts is 3 bar, would still start with return blocked off, you sure fuel pump is priming?
could be crank sensor then is its turning over but not starting, could be a few things aswell. coil pack ok? not got any dodgy connections? take plugs out and have them fitted in coil pack, turn the engine over and see if they are sparking.

Liam

I dunno mate. Wouldnt know how to check :S

williamsvts

16th February 2009, 21:19

you sure you have blocked return and not inlet?

raunchz

16th February 2009, 21:21

Just seems funny it started first time, but now won't start, something must have changed :geek:

williamsvts

16th February 2009, 21:22

dodgy connection/earth or a plug not connected properly?

Liam

16th February 2009, 21:27

you sure you have blocked return and not inlet?

LOL nah defo the return. Im goin to try the crank position sensor tomorrow. Ill get another one. It seems a logical reason. If there was a bad earth surely nothing would work as it should. Again i dunno. :(

Liam

16th February 2009, 21:50

What could cause the ECU light to come on though? I there a few things???

Olly

16th February 2009, 22:28

to find that out youll have to get it on a diagnostics. Should tell you any probs.

Liam

16th February 2009, 22:49

easier said than done, i cant get it anywhere lol

Olly

16th February 2009, 23:03

ok, u tried putting ur foot on the pedal on startup, could be idle problem if it was running up revs, or sensors.

Liam

No, ill try that. Ill give it a go in a bit. :(

take plugs out and have them fitted in coil pack, turn the engine over and see if they are sparking.

from page 2

hold plugs up against your rockers though.

Liam

17th February 2009, 11:10

Sorry mate, what do you mean, up against the rockers?

evans1089

17th February 2009, 11:12

means the rocker rover so it doesnt contact with anything that isnt earthed as when they spark its like 30000 watts lol

Liam

17th February 2009, 11:19

So take the spark plugs out, turn the coil pack upside down put the spark plugs in the coil pack and rest it against the coil rocker cover? Sorry mate lol

williamsvts

17th February 2009, 11:28

lol, you sure you should have been doing your own conversion?
do you know how to check for a spark on none coilpack engines?

Liam

17th February 2009, 12:16

there is defo no spark from all four plugs. is this coil pack or summat to do with the immobiliser. some suggested this to me, but i thought they just shut the fuel off, and its defo getting fuel.

williamsvts

17th February 2009, 12:25

it wouldnt be fuelling either if the immob was fucked or ecu was locked.

Liam

17th February 2009, 12:33

Thats what i thought. Do you think it would be the coil pack?

Liam

17th February 2009, 16:11

Right so ive changed the crank sensor and tried a reset on the ecu, but still nothing. Its still trying to turn over. Its doin everything it should except start. As said the ecu light is on whilst trying to start it. There is defo no spark to the coil pack. I really am thinking its the ecu now. Any other ideas?
