Check your EGR valve and system. EGR should not be on when engine is cold, if its on the car will run as you describe.

the problem is that it has been parked up for 8 yrs, you really need to get a decent mobile mechanic to give it the once over, there are a number of things that it could be, they don't like being left that long & not at least started.

Check on Bimmerfest,com its a bmw forum, I have gotten alot of great answers and ideas for my 1997 z-3 roadster great site.

1st check fuse to fuel pump, and fuse to fuel pump relay.

If they are OK, you'll need to be sure no wiring on this age 17 car still good
(I have a '97 328i convertible, fun to drive, but what went wrong *this* week)
So check for voltage *at* the fuel pump, it won't run w/o power.
If that's ok, then you are down to either a bad fuel pump, or blockage in fuel line, probably at filter.
(a) See if pump is actually pumping fuel out.
(( FIRST, listen, and see if you hear motor running ))
(b) Since you may now already have fuel line disconnected at pump end, disconnect other end, and use bicycle pump, or some other source of pressurized air and see if the line is clear.
In *any* event, I'd change the fuel filter.

p1188 is fuel pump and p0170 is same problem but with air flow sounds like drawing in too much air and not much fuel. pump might be shot.

hope this helps

Check the electric fan(s) if equipped. If it has a belt driven fan, replace the fan clutch. Also rechecking the thermostat is a good idea too, they are sometimes bad right off the shelf.

Hi this is not going to really help but i have sort of the same problem when i have been out in my car, get back in and turn the key.... nothing ,dead well seems that way , but turn the key again and it starts the battery is new 1year old but this happens about once every couple of weeks never happens when the car is cold ! starts first time then . Is this the same as you .My garage said it could be the ignition switch but they say it could also be earthing ,which they will check first . My car is 1998 model 1.9 . Sel

I would suspect that you pulled a wire off when you were installing the water pump. Check to see if you have spark

two straps ..and the filler neck still needs disassembled...remove wires at top of tank before dropping all the way(including any ground strap)
