I got a big problem,and i hope somebody could help me.My car dont start,there'* fuel,but there'* no fire,so i changed the spark control unit and no more fire so i hope that someone'* gonna know my problem.

Does the voltmeter kick to life when you put the key in the igntion and turn?

What you mean?

On your dash cluster, you should have a voltage gage, sounds to me like its ignition or electrical (ie battery or alternator) has gone south. If you have any life in the volt gage then the battery and alternator are ok.

Otherwise, its hard to say

I got voltage there,the engine is turning but it wont start,there is feul but no fire,do you know where is the crank and cam sensor

OK..so the electrical is there. good....are you throwing any engine codes? any Service engine lights coming on?

If there was a problem with the crank sensor, you would be throwing a code.

Does your car have VATS? (vehicle anti-theft system) its almost like the VATS system is kicking in and not firing up the car. Wheres Andy Green when you need him

Andy? any ideas here? Don? Bill? Alan?

One more thing, I have no idea about your car, please add the year and trim level of your Bonneville to your sig, makes this a whole lot easier

Can't be the cam sensor. That'* exclusively for fuel control. Crank sensor and Vats are good places to start. Checking codes, as Jim suggested would be the best and first thing to do.

Try another ignition key first, then let'* see what year and model you have.

Yes i got a vats and my bonnie is a 92 n/a.

I tried to get the codes but it only give me (12) diagnostic code
