Broken down frankfurt

It was the fuel pump. Thanks for all the help guys.

True on M50 upwards. Not sure about older engines...

Fuel pump isn't buzzing. That's probably the problem.

Not sure about e30 but on e36 fuel pump won't even turn on unless there is a signal from the CPS. I thought the same thing, bought a fuel pump, turned out it was the CPS.

They quoted me 215 euro for a new fuel pump, so I learned real quick where the auto recycling center and pulled one for 10 usd. Hope it works.

I'm not even seeing it at this point. No idea what I'm looking for.

Well after removing some coolant hoses you'll need a 3/4 mm hex key to remove it.

[delfin]

Awesome. Hopefully I can get to it without tools. Fml.

On the lower front of the engine. It reads off the toothed crank pulley. Sometimes that wire frays at the base and breaks off. Also happened in my e36. Died on the highway out of no where one day.

Ok after a little searching I see that I have had all the problems to indicate a faulty cps. ie bad idle, random power loss, random.shaking. Where is it on the e30 and how hard is it to replace?

[delfin]

Ok stupid question: what is a cps?

[brutus87]

CPS!
CPS!
thats what happened to mine.
The CPS plug was simply loose.

Air force out of ramstein. I might have to check out that forum if it's not the fuel pump.

[Jesse30]
