I am begining to hate my engine, I cant figure out the problems, and more syptoms are starting to appear!!
For starters, I have had to replace the fuel pump fuse 2 times in the last two days.. Both times I was stranded in the road.. Luckly I had enough sense today to take one of the ones from a light.

Next Im having power surges, asside from having almost no power.. I am still having a high idle problem and I still cant get the electronic ignition to work..

ARGG!

plugging up the vacuum lines has nothing to do with your problem, I just mentioned it 'cause that is what I did to eliminate some issues I had when I was trouble shooting my setup.

you could do the same, but it won't solve your fuse problem (IMG:style_emoticons/default/sad.gif)

... Dad had to re route the wiring for the fuel pump when we where working on the pump because it was not getting juice no matter what we did.. he wired it from the relay to turn on when the key was on.

And you didn't think that particular bit of info was of interest in this situation--why??

OK, now--which fuse is blowing? The one for the fuel pump on the relay board? Or the one powering your new relay? Or is it the same one?

Check the old fuel pump wiring, it may very well have been broken. Now it may be shorting to ground. Result: Popped fuses.

If it's the fuse for the new wiring that is popping, check your new wiring.

Cus I just remembered it (IMG:style_emoticons/default/laugh.gif)

The fuse blowing is the one under the dash.
3rd or so from the right, pretty sure that that fuse is for the fuel pump.

No new fuses installed from the new wiring, no neccecity for it. If it was the wiring, why would it take a month for it to go bad like this? I had it running perfectly (as far as the fuel pump was concerned) for a while.

I think(for what that's worth), there may be a fault in your new wiring. There is no fuse under the dash labeled as running the fuel pump(afaik).My books say the third fuse from the right runs additional headlights, and (horn74 and on). The fourth from the right runs the turn signals, Brakes lights, and backup lights. Are one of these circuits going dead as well? Maybe you should switch the fuel pump to a different fuse?

I think I know the problem..

When dad wired the fuel pump, he used one of the points that turned on when the key was on, now I just put in a radio the day before my fuel pump kept blowing fuses.. I think I am over loading the fuse, and since I got the car home by wiring the pump directly to the battery, I am going to have the pump wired to the battery, and I will have a switch for the pump inside the car. This will double as a anti theift device (asside from the car being very hard to drive)

Does this sound right?

FYI.
An old trick is to run the fuel pump wire off the hot side of the coil. The first 914 I owned was wired in ths manner ......why, you may ask?

It seems that the fuel pump wire has been known to self destruct inside the BIG wire bundle. It runs off a 25 amp fuse in the relay board....exactly why this wire gets overloaded is a mystery to me. I found this in my 914 yard car. It had fried itself and a few neighbors.

I said it was an old trick, not necessarily a good one.
This runs your fuel pump whenever the ignition is on.....also, no fuse in the line.

I run my fuel pump off a fused circuit on the fuse pannel (don't remember which one), then thru a off/on switch. My pump is up front.

The main point I was trying to make was about the fried wiring.

Use a relay switched from the stock location powered directly from the battery! Relays only take ML Amps to trigger!

that's such a good idea the factory built it into all the cars - /4's already came with a fuel pump relay, and for many people, the problems start when they decide to stop using them ...

I fix them ALL. I even use the factory wiring/relay/fuses to power carb pumps.

We are going to use a relay as well. Gona use one of his trusty 951 relays with the simple connections..
Brad, what do you mean you fix all of them.. How do you fix them? with different wiring? if so, how? And why?


Thanks
Andrew
