I have a 911 that won't start. It cranks over but will not start. I
pulled the fuel line off the fuel rail, and with someone else holding
it, I crank the motor over for atleast a minute, and no fuel came
out. So either the fuel filter is clogged, or I have a fuel pressure
problem, or a fuel pump problem. So I hope anyone can voice some help
here, thanks...........

Ok, so I finally pulled the fuel pump
out from under the car. It is a Bosch 12V electric pump. I placed 12
volts to the terminals, and again it sparked as I touched it and the
pump started to hum, but not buzz like a normal pump, and as
suspected, it seems to be jams or locked up. I called a Bosch
rebuilder, and the tech was asking me if I can see in the top where
the fuel inlet is if the fuel was spinning or feel it spinning and I
said no, he then said from what I explained to him, that the pump was
locked up with some kind of debris. So, I think I have found the
problem..............BUT. When I was under the car removing the fuel
pump, I notice the fuel lines coming from the gas tank. But I did not
see any "fuel filter" to the fuel pump. I know there is a
filter in the back of the car up inside the passenger's side, but
what filter the fuel to the pump? So lets assume I get a new pump
replace it, car start and everything is okie dokie. I go to a gas
station fill up and get some bad gas and something in the fuel get
stuck in the new fuel pump again??? Then what ????

I don't know your car, but there is probably at least a screen there - ask
the dealer if there is a filter betwen the tank and the pump - if no, drain
some gas out through the hose to the pump to get any additional debris out.
And, I'd change the fuel filter

Isn't this a 1996 911 (993)?

I am following this without much to contribute. Sorry, Scorp. But when
my pump goes out, I'll know what to do, so thanks for that. Where was it,
btw?

I thought it was a 996 - if it is a 993, I have the manuals and can look it
up (if I ever have time to think straight)
