E34 1995 525i Touring - no start

[emandru 17]

Hi everyone,

I'm looking for some help once again as I'm stumped on a no start issue with my car.  A little while back i did a trip up to Whangarei and car drove perfectly. Parked up for the day and when I came back to start the car up that evening it took numerous cranks to get her going again. About 10 mins of trying? Fast forward, I got back down to Auckland parked up and then tried to start the car again the next day. Started first go. And then the second day, same difficult start. Now it wont start at all so I've tried the follow. The engine turns over and cranks but will not start.

1. Took the fuel relay out and jumped pin 30 and 87 in the relay holder. Can hear the fuel pump turn on.

2. Swapped the fuel relay out with 3 different relays i got from the scrap yard. Still no start.

3. Pulled a coil pack and spark plug out. Grounded them and cranked the engine. No spark. Plug was dry when removed.

3. Measured resistance of the crankshaft position sensor. Reading of 502 ohms. Seemed reasonable but swapped it our anyways with a known working one from another car. Still no start.

When I crank the car over, I try to have my partner turn the key and me listening for the fuel pump to turn on. Can't here the pump turn on. Also there is no gas smell coming out of the exhaust pipe when cranking. I'm not sure what to do further? Any thoughts?

Cheers

pull the rubber boots back on the crank and cam sensors and check if the wiring is all crumbly etc ,

Thanks Brent. I ended up checking the whole system multiple times and then decided to go over the EWS system. Ended up being the key ring antenna. One of the wires had broken. Soldered back up and started first key :).

Interestingly enough it was cranking but no start and confirmed no fuel or spark. . That's what threw me off too as I would have thought that an EWS fault would prevent cranking too.
