Replaced E30 computer with a 173 and still cutting out

[gunter 0]

Hi there,

So my 325i started cutting out a while back and I bought a bosch 173 which from many different forum searches said cured the problem and it did for a while but now its back.

I'm not saying its the computer because the 173 seems to have fixed everybody else's problems

Any ideas?

Cheers

all these things can be intermotant

fuel pump dying??

faulty ecu relay??

faulty fuel pump relay??

crank sensor??

alarm wiring??

need to find out when it dies , does it still have spark???

then start looking at fuel stuff .

if no spark then the electric side , lie crank sensor and relays and power supply to the ecu etc

Sweet that sounds good. Like you said its intermittent and doesn't usually last long enough to kill the motor but it has a couple of times. I think but I'm not sure that its a fuel issue but I'll keep watching and if I discover what it is I'll post back
