M50 glitch/fault/problem

[Ricbmw]

Hi BMW owners, I have now my first BMW e34 M50 ( no vanos) and it decided to give me some grief. Hitting the net and reading a lot of faults with this model, I have followed all the quick checks I can. Fuel side is fine with every thing in the chain working, relays, pump, pressure. I did the fuid spray in the intake and still no start. (turns over but will not fire). Took off a coil pack and did the screwdriver test, no spark. Following common advice on the the net I changed the CPS out with no result. Put both CPS units on the multi meter and get a reading of 520 ohm. I have full electrics on the car but between this system and the plugs theres a problem. I can only point the finger at the ECU (0 261 200 403). If I reset the computer and still have this problem am I on the right path?
Regards to those that can help. Here it is unburnt, but soon maybe...

Download the Bentley service manual pinned at the top of the 5 series subforum. It's a great troubleshooting tool.

Hi Torque, Did that a few days ago and yes it's a good guide. Still have my problem. info not going into the ECU or ECU not letting it out. Have fitted a new Crank sensor with no result. New battery, new starter motor, new fuel lines, new plugs, new relay's, new hoses, new rad core, new "steel" water pump.. Will battle on.....

If anyone knows, the Bentley refers to testing the crank sensor and getting 540 ohms for the m20/m30 sensor. The sensor supllied by the dealer gives this reading as the old one does as well. Bentley states for the m50 is much higher, is this critical?
