Sounds to me ya need to open the "boot" and find the access door to top of fuel tank check hose on pump inside of tank for damage, always disconnect negative battery terminal before working on things.

We do negative because that's the ground, a chassis ground, any metal that's not a positive terminal is negative if you disconnect it first you open the circuit to everything, and if you accidently bump any metal (aside from the positive terminal there won't be any sparks, you can pull both, good idea if your arc welding just disconnect the neg first and reconectn the neg last,(remember the spark thing)

So if I disconnect the negative and Im removing the wires going to the starter and bump the car it wont spark?

That's correct, you now would have an open circuit, it cannot spark if the negative terminal is off of the battery, unless you have some huge capacitor added to your stereo amp that is. In that case pull that negative too.

Your welcome Thomas, things were good till I lost my job/wife's job, house and she came down with Ovarian cancer, poor Tania (my G60) needs some lovin', but still love to drive her. All the period correct upgrades, now she needs front spindle or wheel bearing housing, the bearing spun in it's boar. I should have maybe used locktite cylindrical locking compound as the bearing did not fit as tight as it should have and two years later wore out it's housing. after that the next upgrade will be to put VR6 gears into G60 trans, 1st gear is silly with this much power, I will one day also put an electric clutch on the g lader somehow and add a turbo for high Rpm boost. I'm hoping I can do this to the g lader.

An electric clutch on the g ladder? As in to engage and dis-engage at will? Plus a turbo? Let me get this straight-thats like having a twin booster at will? Sounds crazy but do-able... I wonder if they make an electric clutch on a g ladder...I haven't looked it up but being belt driven it would seem its always on always turning. I wish you were my neighbor-I would be at your place picking your brain all the time. I haven't named my baby yet. I was romping through the mountains and down shifted for some reason when I shouldn't have and completely blew my cylinders. Now my sparks get all gooped with a ton of oil so Im assuming that shes dead and the rings are out. I would love to tackle her and start pulling the engine but I lost my job, and house too! Its tuff life noggins out there, but I parked the beast and she sits still waiting for her prince to return. I hope your wife has made a full recovery. Its even harder when our loved ones get sick and Im very sorry to hear that, my deepest sympathies and condolences go out to you and her. I will keep you guys on my mind and wish you the best as my days progress... Im happy to hear that through all of this you were able to keep Tania.

Thanx Thomas,

The Idea of twin boost, is (for me) having boost from G-lader already available @ Idle, it's low at idle and being bypassed but it's there, the G-lader was not meant to have an under drive, I think stock pulley is 78mm, for a max boost around 8psi and the rest if any is wasted through an assortment of junk, the stock red line is about 6200rpm, most people use a 68mm pulley, I have a 63mm on there and no rev limit or speed limit on my Chip, so I could easily over rev the G-lader, so from the whole shot till 5000 rpm the G-lader could push till the turbo really starts working and the G-ladder as RPMs and turbo boost come into play, I'll have to test and tune to get it down, but that's my plan. Mercedes Benz uses an electric clutch on their "Kompressor" the C230. The Benz Corrado wanna be looking car.

That all sounds very cool Randy! How where you able to get no rev limit off of your g ladder? I understand the concept of smaller puller higher rpms... also it seems to me that 8 psi is incredibly small amount of pressure. i would think it would it would be so much higher! Im new to the concepts behind a super charger. And if you have no speed limit on your chip how fast can you get to going? This all sound very interesting. When i start rebuilding my baby Ill be sure to post post post everything on here. Right now im getting ready to move to South Texas, thats not close to you eh? Jk. And you had to mention my other favorite car to huh? The Benz Kompressor... i can see where they came up with that name.

I've checked the fuel pump sends juice into the black box underneath the petrol tank n sends it straight back again there's a spare wire by the temp sensors same as one of the fuel pump wires its disconnected and have the feeling it belongs somewhere

Well Thomas,

My favorite VW parts place so far is :

http://www.bahnbrenner.com/

they have / had a stage IV kit for the g-lader G60 Corrado, and well boost wise I'm pushing close to 18psi without over revving but also keep in mind that's also canceling out the engine vacuum, ever rev an engine and then cover intake with your hand, so 8-18 psi over that. All the internals of g-lader and intake have been ported and polished, you can see picks of the things "they" do to g-lader at bahn Brenner, I did them by hand with dremel tool, also port matched throttle body and intake. made my own "howitzer" cold air intake for g-lader 3", bahn Brenner provided chip, I requested speed and rev limit delete from stage IV with 63mm pulley chip (could have gone to a 58mm pulley at the time but I feel that's too much, 63mm is just a lil more than the next guy(most use the 65mm)). You opened up a can o worms asking me about my baby. We still need a front mount intercooler, planning on adding small electric fan to stock inter cooler for high heat/traffic days. Right now taking care of the Mrs is number one, so not much time spent even outside never mind the cars. My turbo friends say I need meth inj. But I want to use CO2 spray on inter cooler and intake manifold.
