HELP Needed !! 94 530i V8 engine won't start

Hi everyone,

My 530i V8 (M60 engine) won't start. The fuel pump seems to be working (took it off and tried it with direct current. Changed the Crankshaft sensor and fuel pump relay. It cranks but it won't run. There are times when it sounds like it is about to but then turned back to cranking again. Visually the camshaft sensor cable is already very stiff, the same as the crankshaft sensor cable before changing it.

Anyone has ever had similar problems? Thanks.

Pull a plug and see if you have a spark.

Right...haven't checked that before. I'll do it tomorrow. What could it be if there is no spark?

Thanks.

Pulled a plug and found sparks. Like I mentioned, changed the fuel pump relay and crankshaft sensor. Now placed a new fuel pump just to try. Find out that the fuel pump is not even running when key is turned to "on" position (last position before starting) Even after starting, no traces of fuel in the hose once removed. What could it be?

Thanks.

The pump doesnt cut in until you actually start to crank over, and this is controlled by the crankshaft sensor.

Sounds to me as if the camshaft sensor has died as this controls the injectors and timing, so if this has gone it will not demand any fuel.

Thanks...just a thought. Since I have new pump and crankshaft sensor, shouldn't it pump some fuel when I crank the engine over? I tried cranking it without plugging the hoses but there is no gasoline pumping out from the tank??? I will try to get new camshaft sensor and see if it will help, and I will inform further.

Hi Marti 5,

I have changed the camshaft sensor but it doesn't yield any result . Now, I have new camshaft and crankshaft sensor, new fuel pump and fuel pump relay. I have sparks, but I believe that the fuel pump is still not sending any fuel to the front. I haven't checked now by opening the hose, but I believe it is still the same. I checked the relay and it is good. Fusible links are good and all hoses and pipes. What can I check next?? Is there a collision inertia switch that is accidentally pushed down for some reason?

Please help....I want to get this car running cause I'm a bit tired of driving my Range Rover Classic daily. I need to drive my BMW as well :-D

Thanks.

I've checked, the fuel filter isn't blocked. The fuel pump is not running for some reason. I connected a direct current from a spare battery and the pump runs and I was able to start the car, but as soon as I disconnected the battery, the pump dies off and so is the car.

What could it be...I know now I need to close everything in the back and move up front, but with all the new sensors and relay, what could be next???

I would say there must be a fuseable link somewhere, Im not sure at the moment I will have a scout around my files.

Ok the fuseable links are under the rear seat. bypass the link and see what happens.

If that fails I can only think of one other thing and thats the ignition switch.

The fuseable link is good, is there only one or there are more? The one under the seat just behind the battery is good. Could it be the immobilizer? How could I check if it is? Is there any way to bypass it? What ignition switch? Where can I locate that?

Thanks.

Ok, When you checked the relays, can you tell me where the ones you checked were located.

If it was the immobilizer , even by direct feeding the pump the car would no way start.

Ignition switch is where you put the key in to start the car !!

I checked the one on the right side (passenger side for left hand drive) Where the DME, ABS and ASC ECU is also located. The fuse I checked from the e-box on the driver side where the CCM and LCM is located.

Ah....so that ignition switch...I thought there is another one, like an inertia collision switch :-D I do have an extra alarm system in the car, could it be that it is the culprit? It's a carguard 850S alarm system.

Ah! the extra alarm system could well be the problem a friend had one fitted and after 2 months had problems with none starting and battery drain.

Disconnect it and see what happens.
