2.3 20v Coupe wont start ! Advice needed !!

[coco]

Right guys, i managed to get the car inside the garage today to have a look and see why its not starting.

First hurdle to get over was getting the bonnet open ! Cable has snapped so it was no mean task just getting into the thing to have a look under the bonnet !! managed to reach in with a long screwdriver and release both the levers on the hinges and got the bonnet open

Fitted a new battery as the one fitted was flatter than a ducks foot

Next problem was that the ignition came on instantly when i connected the new battery, even with the key in my pocket !!!!! Pulled the bottom section of the dash off and got the multi plug off the back of the ignition barrel and managed to work out which pin on the plug did what and got it cranking over finally

Sure enough it has no spark, first thing i checked was the rotor arm to see if the dizzy gear had broken up, not the problem as rotor arm turning round nicely on crank.

had a check to see if the dizzy was getting power, with the ignition on i have 11.35v at the red and black wire on the dizzy multi plug, 5.00v at the centre pin which is green and white, and the brown and white one is the earth. Are these values correct and what i should be seeing at the dizzy ????

Anyone got any ideas as to what i should be looking at next to try and get the old girl into life !!!!!

Cheers folks.

How do i get the codes ?? Do i need a VAG com to get them ????

[spink]

dont need vagcom,read this http://www.20v.org/fault.htm

if you are planning on keeping the car i would get some vagcom cables or buy a U280 scanner off ebay(dont need a laptop for this,both options are about £25

Cheers guys.


Any other common problems i could check for ??

[quattronutter]

is the fuel pump working?i assume your getting fuel ok?

[spink]

he's not getting a spark.

Other possiblity's are missing tooth on flywheel/missing timing pin(on back of flywheel) both easy enough to check once crank sensor's are removed(both these should show code's.Duff coil/ecu are very unlikely but a possibility.Need a multimeter to test coil.

[spink]

have a read through this.

its for the turbo engine but is much the same

[quattronutter]

speed read it....could be the coil,best to check codes and go from there

Will my car have the large diagnostic socket that the U280 tool uses or do i have to read the codes using the LED method ???

Mine is a 91 year, unsure what type exactly ( B7 etc etc !!! )

[spink]

no it has the smaller 2x2 connector,get from here.You can use the led method on anything upto about 1996

Any chance you could post a link from ebay so i know im actually buying the right thing !!!!!

Cheers
