[pastures16]

well where do i start steam cleaned the engine on tuesday had a missfire wednesday morning took the coilpack cover off the plugs were soaked so i dryed them off sorted sweet as a nut got up this morning started fine then after about a min it cut out the oil warning light on the computer came up tried turning it over not firing so towed it down to work took the coilpack cover off again and the plugs were covered in oil rocker gasket i thought so cleaned it all up again put it all back together still not firing well tested for spark all ok so i cracked open the fuel pipes on the bulkhead turned her over nothing fuel pump maybe so took the cover off the tank and tested for power to the nothing there where do i go next lads is the ecu telling the pump not to pump im stuck now cant get a hold of ben to plug vag com in any help would be more than welcome

Steam cleaning the engine is a BIG no no on these

cheers mark that dont help mate

Check the fuel pump relay and fuse. (Fuse is #13) Fuel pump is triggered by the RPM / TDC senders on the side of the bellhousing / engine (left hand side) Check connectors and make sure they are dry and secure.

hi mate i checked the fuse its ok how do i test the relay it clicks when i turn the key

You can run the pump direct by fitting a "jumper wire" in the relay location. Can't remember which pins, I'll look tomorrow at an ABY. Or you can remove the plastic cover and manually push the contacts shut, and get an assistant to try starting the car while you do so.

Let's know how you get on.

cheers mate ill check back at 1 to see if youve sussed it

I suspect the pump won't run due to another fault - possibly the cam or crank position sensors have got water in. You can also check the connectors behind the head which connect the ecu loom to the engine loom for water.

Get a hairdryer out and dry everything off

You really need to pull the codes after an attempted start. if you can't get Vag Com, you can use an LED.

I think Mike is on the money here. Its VERY bad form to pressure wash an S2 engine bay without the right precautions. You likely have waterlogged one or more connectors related to crank or cam timing... or the connectors taking primary voltage to the coilpacks... or the MAF connector can easily get soaked causing a no start. I've seen that once.

Theres a bank of connectors on the bulkhead in the engine bay. Two white, a blue, a green plus a grey and black. I can't remember all of their notations from memory but they all connect sensors and coilpacks to the ECU. Remove each one at a time and dry them out.

Try resetting the ECU by removing the two fuses under the red clip marked 'MOTOR'. Leave them out for a minute or two then replace them. This removes any fault codes that might be stored. Try and crank the engine again. If it starts at all then keep it running gently to dry it out properly.

If it doesn't start then you'll need to pull faultcodes - with VAGCOM - or with an LED as per the blink codes nonsense... As Mike says too !

Well if you'd asked first, I would have helped you by saying 'Oh no, don't pressure wash it, you'll open a can of worms' or something along those lines

[Jamo]

I didnt say anything when i saw the thread with pressure washing was thinking "oh ooh"

your really going to have to check and dry all the electrics if possible

oh poo a jet wash disaster,i only know that the green n blue are for the knock sensors.i know it might not be any help for you but at least u know where they go now.hope it all works out for you.the fuel pump relay has a fuse holder in the top i think if u put a 15amp fuse in it then it works that way to find out if its ok ask jason he might know.

[pastures16]

well you all got it wrong lads bens the daddy vag com showed no faults then ben got the bible out (vag wiring diragrams) done some tests and guess what fuel pump even after id test it as well anyway sals dropping one off 2moro

Glad you got that sorted, at least you can get back on the road and look forward to an upgrade rather than major repairs!

ahem....what did i tell you the other cok jockey! its the fuel pump...no its not...yes it is...no its not...yes it is...not its not....yes it is ...not its not...yes it is...yes i know it bloody is i told you that the other day...grrr......
