I have no spark or injector pulse sometimes it

You got a crank sensor at back,on top of bellhousing.
Injector pulse, I believe is controlled by hall effect sensor in distributor, as well as spark

The fuel injector/ fuel pump fuse keeps going out on me and i have to keep replacing it. i can only drive about fifty feet before it goes out.

The most likely problem is the fuel pump itself is shorting out,it will have to be replaced to repair the problem,it is in the fuel tank.

No gas coming out the injector and there is gas pressure to the injector?

Is there an injector pulse going to the injector?(an electrical pulse to fire the injector).
Is there spark at the plugs?
If the pickup in the dist is faulty you won't have either one.
If your vehicle uses a crank pickup with or instead of dist pick up....if it is defective pulse.
The above is 90% cause of no pulse....other is computer problem 10%.
If you do have a injector pulse and no spray.....and have fuel pressure....change the injector.
A quick check for spark is spray a little starting fluid in it.....if it starts on the fluid....spark is present.

How difficult is it to replace a heater core in a 1993 audi 90 quattro? can znyone give me an idea on how to remove the dash?

when u do this take your time, don't force anything, if it wouldn't come out then u missed a retainer somewhere, also the heater core requires taking apart the air ducting, and make sure everything is hooked back up, take allot of picture's before hand to document where everything goes, the manuals are for professional factory tech's and they assume allot of basic knowledge, in other words they don't spell out every little detail.

Injector pulse comes from Cam sensor, If you have a BAd CAMSHAFT sensor you will not get injector pulse, replace sensor and that should solve your problem. Good Luck and thanks for using FIX YA

Window doesnt work

you need to take a multimeter to the wires on the motor and if voltage is going to the window motor then you have a bad window motor and it needs to be replaced. I hope that helps you out.
