Turns Over But Won't Start


Best Answer Its a min , 12 February 2019 - 10:19 PM

Hi all.

 

Just a quick update to let you know it's all sorted and seems to be running fine. Did static timing, fitted some new plugs and checked/cleaned all connectors. Turned over a few times, and after a bit of coughing and spluttering (both me and the car), she burst into life.

 

Thanks for all your help and advice.

Any suggestions on new coil?

 

998 A+, Minispares stage 1 kit, electronic conversion kit and de-ballasted for 12v with NGK BPR6ES plugs..  Was thinking the Viper from Accuspark.

 

https://www.ebay.co....tm/192337383535

 

Any one used this or will it be to over the top for my setup?

 

Cheers.

and the point of spending more money? just get it set up and running.

 

Hi nicklouse,

 

If I can avoid it, I'm more than happy not to spend money. I was forward planning as a last(ish) resort as I remembered having a similar problem a few years ago where I had a lumention coil fitted and although it all seemed to be ok, it just wouldn't start. I had the current coil hanging around and as I knew it was a 12v 3ohm, tried fitting it on the off chance and never looked back...until now.

I’ve seen this exact same thing before. Started, spluttered died. Then nothing.
Checked the obvious, fuel, spark, cleaned the spark plugs etc.
The battery died from cranking, we called the AA who came out to jump it.
It was spinning nicely with the jump pack directly off the AA van, but even with easy start down the carb it still wouldn’t fire.
Rechecked spark, fuel etc. All seemed correct.
So as a punt and desperation, we luckily had a new set of spark plugs in the boot. Fitted plugs, (old ones black, sooty and slightly damp with fuel, even after cleaning). First turn of the key it fired and run up to temperature normally, so don’t consider the spark plugs okay just because they were cleaned.

Hi Firephoenix,

 

You've not hacked my pc have you? Haha.

 

New spark plugs arrived today but thanks for the post as I'm hoping it is something as simple as this.

 

Cheers.

Float vent is vital to let atmospheric pressure in to push fuel up the jet. I did wonder if it could be by means of an overflow pipe, around the clutch cover, that might have got dinted. Earlier ones were just a hole through centre of the float chamber lid, covered with steel cap.

Hi Ethel,

 

In which case, yes, I've got a copper overflow pipe from the float lid down and around the clutch case (wok) to under the engine. No visible damage and tried blowing through and no obstruction.

I'm now thinking if it's something like bad spark plugs or leads, something really silly

That's what I'm thinking/hoping. I've got a new set of plugs so will try them.

 

I'm also wondering if it could be electronic module that has gone. As I don't know how to test this, or even if it's possible to test, I am going to try replacing with points and see if that does the trick.

If you replace the points, you can time the dizzy  ---  Spot On.

You've got a spark at the plugs though? Does seem like the module works after a fashion at least.

If the module failed it wouldn't spark

Cheers guys.

 

Seems pretty unanimous so hopefully one thing ruled out.

Not had a chance to do anything this weekend.

 

Hoping to have a 'POETS' day and work on her at the weekend. Here's my plan:

  • Clean/check earth strap and if I can find the other spare, add a second.
  • Clean/check all the wiring/terminals going to the coil, starter motor and solenoid.
  • Check fuses/fuse box
  • Fresh fuel and a dash of Millers for extra spice
  • Check/clean carb and float chamber
  • Fuel mixture - set carb back to basic (jet flush with top and two full turns)
  • Check/adjust tappets
  • Set static timing
  • Gap and fit new plugs, leads and dizzy cap
  • Check/clean rotor arm
  • Check coil resistance
  • Check firing order
  • Test compression

And I think that's about it. Unless I've missed anything or if anyone has any other suggestions/advice.

How about a new distributor cap? It may be shorting/arcing and not going out to the plugs. It may spark when the plugs are out, but under compression, the resistance is higher across the plug gap, and may be causing a short in the cap.

I had a problem with a distributor that just gave up on me. I had electronic ignition on it. When it suddenly quit, I changed back to points and it still would not work. I change the distributor and never looked back. I never found the problem with the original!

Hi Ian,

 

Thanks for the post. Already listed a new dizzy cap but given the quality of parts these days, definitely one to look out for.
