Im not going to read the thread over lol I posted b4 like a month ago.

Anyways do you get spark? As in pull the plug out and crank the car. Do you see a spark on all 6 cyls? Ok if that good then fuel. Jump the fuel pump relay , fuel? if you get all that then looking in to CPS ( the two off the fly wheel ) Check main relay ( swap with the fuel pump relay ) Dont worry about the o2 relay car will still run with that. Can you make a video?

Do you own a Bentley manual? If so check the wiring diagram for the ecu and u will find which wires are ground and hot. Then all you have to do is test these wires.

If you don't own a Bentley manual, get one.

starter motor?

Good idea. I'll try to do that

starter motor?

No, it cranks. Just doesn't fire

There is spark and I get fuel at the regulator, so it must be an issue between the FPR and injectors.
When I undo the line at the FPR there is a little back pressure. Could the FPR be bad and not regulating the fuel correctly?
Or is it the injectors not firing and its building up pressure?

[jlevie]

There should be no pressure at outlet of the FPR. If there is pressure something is obstructing the return line line to tank. That could cause excessive pressure in the rail and flooding of the engine.

I don't see why something would be obstructing the return line, it ran before.
The injectors have to be not working?

[craiggroves91]

Holy Shit!
I think I have the fuel going into the wrong hose at the pump!!
Fuel should be coming out of the FPR, not going in?

Right now I have fuel going in!!
Its because I used a late model pump and its way different

[jlevie]

If you mean by "late model pump" you mean the in-tank pump for an 88 or later 325i, that pump will not work in your car. It does not have a fitting for the fuel return line and oly has an outlet fitting. The transfer pump you took out has an 8mm fitting for the return and a larger fitting for the outlet to the high pressure pump. So right now the pump is pushing fuel to the outlet of the FPR. You must use the early in-tank transfer pump.

ITS BACK! HOLY CRAP!
I put a 318is pump on the early model bracket worked like a charm. I can't believe that was the problem this whole time.
