No started
 

Hi comunity! my 928, 1985 S, Doesn't start. I Change the fuse, the relay, the fuel pump, the gas filter of course, and the engine doesn,t wake up. Change the gas, the battery is ok. And, no run.... only no explosión, And I, dont now what is the problem. ? How can I to work out that problem, to fix? I, think is and electrical problem, cause, the mechanical mothers and repairs are ok¡.
Somebody can help me, please... thanks..

By the way, and electrical technica0, inform me the last 5 fuses , don,t have energy. No light . .. (May be the rats eat the wireless) ?

OK, you need to give more history on the car. When did it run last?

Now you need Spark, Fuel, Air to ignite. Check Spark, Fuel to intake, Air flow.
Clean all ground connections, of which there are many, plus Battery ground and Block to chassis ground.
Clean fuse panel and fuses.
Does fuel pump run?

Check simple things first!

Not Started the engine
 

Hi Harborman, The car does,t run last about 6 monts ago. Before run good for more than 14 years, only minor repairs.
The spark plug have glint. The aluminum gas line near the block have Fuel. I don"t now how I can measure the air flow..
I,m going to clean all ground conections as you recommend..
The fuel pump, it has no energy, does not work. I tried to put directly energy and nothing happened.
We keep in touch, ant tell you what happened!!.
Tks a lot..;)

Sounds like fuel pump is your problem if it doesn't run. Check the grounds and follow power to the pump through the relay. You can try bypassing the relay for a test. As for air, check the MAF. But it looks like you have a fuel issue.

I would like to TkS you for your prompt response and assistance whith my issue !I going to work that and give you work results, ASAP.

Well good luck on finding your problem. Yes, my BMW Z3 is a neat car. I was fortunate to get it from a friend who kept it in top condition. I call it a new 2000 Z3! It's a 5 speed stick shift. Only problem I have is getting in and out with the top up, considering I am 6'3" tall.
