No Start Problem

My 1987 328 GTS seems to have developed a fuel delivery problem. It sometimes will start, but other times not - exhibiting typical indications of no fuel to the engine.

Are there any things I could check on my own before going for a new fuel pump?
Maybe filters or intermittent electrical connections?

Filters can cause poor delivery. But you mention intermittent. I believe a clogged or dirty filter would be definintly more all the time once it becomes a problem. But yes the usual suspects are easier and always a place to start.

Don't know about your older models lines, or whatever, but sure you'll get a good response.

I've never had a fuel pump not work intermittently.I've however had several intermittent electrical problems. I'd start with checking voltages with a good meter paying close attention to grounds. Could be the pump but mine have always seemed to go and never work again. I'd turn on ignition and listen for pump. Then measure voltage at battery,fuse box and pump. If more than -.5 volt (drop) then check wires, connections grounds etc. If full voltage at pump but no sound/won't start then put gauge on fuel rail to check if fuel is present.if no pressure and good voltage then new pump is in order. Good luck, Bill

When does it not start? When warm or after it has been sitting for a week?

Could also be an accumulator of fuel pressure problem. (air bubbles in the fuel system)
