Update: What can keep the engine from starting if the fuelpump is running and der is spark ?



Driving down the road i turn on the back window wiper, when it dident wipe i turn it on again and left it on, 5 sec after the car died and could not start again.

The wiper had caught the joints between window and rear door and then the wipermotor used alot of amp and something broke

It is probably a wire there allso feeds something else there burned over or the wiper wire burned over and touch some importen wire.

It smelled burned near the fusebox inside but no fuse where broke there or in engineroom.

The car is parked near a traffic light in the city so i would love to now where to look or what to look after and if anybody in here have any wild idea i would be very grateful, please please use 2 minutes and drop your thoughts

Ill give a night in town next time you are in Denmark

 

There are some fusable links on the "port" side, i think, around the top of the wheel well inside the "engineroom". I'm not sure how many there are, can't remember. They will be heavy red wires with like a three inch section of what looks like black shrink tube then I think to brown wire. When you say you smelled burning electrical fusable link is what comes to mind however I have not had one go since many cars past. Good luck, search around this site for exactly were they are.

I have now torn the dash apart and looked around with out finding any burned wires or circuit boards.
I have allso measured all fuse and relays in engineroom and behind the door and all worked fine.

I suspect the ignition switch but dont now what voltage there need to be where and when and Haynes/Google dident help.

Can you help me with what current there need to be in what color when off, ignition, on ?
And do you have any other ideas ?

I live far out on the country and havent been appel to go anywhere for 3 weeks so i would be very grateful for any help

Can see i forgot to mention the rear window wiper still works, strange...

Anyway, i took a look at the ignition switch and it looked fine and there where current true to all wires so iam now back on zero.
Unless it dont turn on all the right wires when in "start" ?

Acc : 1 - 3 - 5 6
Lock: 1 - - - 5 6
Off : 1 - - - 5 6 - 8
Run : 1 2 3 4 5 6 - 8
Start:1 - - 4 5 6 7 8

Most wires inside
Circuit board inside on floor
Spark
Fuelpump running
Ignition switch

 

With security on the engine starts for a second and then dies, is there anything else there can "kill" the engine if there is fuel and spark ?

 

Still trapped at home, anyone have a idea for what to check next because iam out
See video above for symptoms....

 

Pull a spark plug and see if its wet. Can you get a code reader from anyone?

 

If the "security" light in the instrument panel is "on" when you start the engine, and then the engine stalls, the Pass lock system "thinks" the vehicle is being stolen, and the computer turns off the injectors. Is this what is happening to your vehicle?
