210 A14 Not Firing


Recommended Posts

So, my 1979 B210 wagon has decided it wants to be stationary. I drove it to and from work today, to a buddy's house, to and from Taco Bell, and then as I went to leave my friend's place, it wouldn't start. It ran perfectly all day until now. The engine turns freely, but it won't actually fire. It's acting like it's flooded. I will have to look more at it tomorrow to give more details, but any advice would be well appreciated. Thank you!

Pull plug wire off and stick old plug in end, (or screwdriver) lay on grounded surface and crank engine over... got spark?

 

Yes... it's fuel related

 

No it's ignition repated

 

 

That was easy. You are already half way to getting it running or at least knowing where the problem is.

 

 

 

Look on front of carb at the glass window. Got gas???

 

Yes...well the gas has got as far as the carb at least.... might be ignition.

 

No... fuel delivery problem. Out of gas, plugged filter or line, faulty fuel pump. Inlet needle stuck, float stuck. Carb screen plugged.

Do you have gas? Is your fuel gauge working? if you have gas, take out air filter cleaner and yank on throttle and see if gas is squirting from carb, if not check fuel filter, if filter has gas, check fuel pump.  If gas is going in carb, do what mike says check ignition, specially rotor.

Alright so I did some testing and found that my fuel lines were good, and everything fuel related was as it needed to be. As expected, I found the problem to be ignition related. I'm not getting any spark from the coil itself. I plan on replacing my coil today and seeing where things go from there. Before I replace it, I'm also going to check the wiring to and from the coil. Just to be sure it's not something trivial like a bad connection.

'79 is an Electronic Ignition.

 

With the key ON briefly ground the negative side of the coil with a jumper wire... you should get spark when wire removed.

 

 

Yes there's spark... coil is OK could be module.

No spark.. coil is not working or lacking power.

 

Use meter or test lamp to check for power to positive side of coil.

 

Yes there is power .... coil may be bad

No power.... ignition relay not working.

 

Find ignition relay, does it click when ignition turned on?

Is there power coming from the ignition switch?

 

 

 

Check that the distributor is securely mounted and grounded. Grounding is extremely important.

Take distributor cap off. Rotor look ok?

It will be attached to the negative battery cable (or near the post) and bolted to the sheet metal body. You can run one from the block to the body if you want, yourself. Use 10 or 12 gauge wire and secure it well. A good spot is from the metal engine bracket to the base of the rubber engine mount isolator.

Hey everyone, thanks for your help. I got ol' Rusty up and running again. Sorry for the absence, there was a death in my family and I've just been busy with life in general on top of that. But I really appreciate the advice! +10 points to datzenmike, as it was a burnt out ignition relay. But thank you, once again, to all who offered their help!
