Elecyronic ignition

[Sweet Shock]

Hi I got electronic ignition fitted today by an auto lec and the problem is, It’s a bugger to start after being left for 30 mins. When you get it started it starts no problem everytime but it takes atleast 30 40 cranks to start. Anyone got any ideas. I plan to take it back tommroe. Auto lec has a good reputation. Thanks Pete

Hi Pete has he got a full 12 volts to the coil all the time & is it the proper coil to suit

[Sweet Shock]

Coil is a Bosch hec 716 and I dont no what he has done

If he hasn't already, get him to use the resister coil+ as the switch wire for a Relay. Then send full 12V to the relay as the +, this way it'll crank with 12V..
Reid is right on the money

Is it a new elec dissy or old one?
I fitted a new elec dissy and coil from a seller off ebay

And never looked back.
The Old elec dissy had excessive sideway shaft play and it played up
Like similar to what your going through.
Elec dissy,s  require the bosh716 coil as you stated.

Is there any dramas with your key ignition switch?
Try putting a live 12v wire to the + on the coil
And see if it starts easier, if it does it might be your key  ignition switch giving you greaf.

Its a new dizzy and my concern is that they new that it was not starting properly and they still let me take it, they had the van for over 24hrs. (Was only gonna take an hour)  Also the reason I got them to do it is because it took 9 cranks to start on gas anytime I started it for the first time then it was fine for the rest of the day. Petrol was never a problem but now It took me 5 mins of cranking in coles carpark last night.  If they couldn’t fix it in 12 hrs then what chance have they got considering this is there field of expertise thanx Pete

If it's on gas do you have it fitted with a purge button they can be a bitch to start in cold weather I uste to start my Coaster on petrol & run it till it got warm then switch to gas no problems starting when hot & in my escort which was streight gas we fitted a purge button which held the sollonids open longer for starting Maby thats the problem & not the ignition Cheers Reid

Just asked the auto lec and they have no idea why it wont start, so it looks like ill have to go back to points.

could it be the ballast resistor [if it still has one] i know when mine started to go it took ages for the thing to start.

Jeff McPherson Auto Electrical is my car sparky of choice. I've been in the trade for nearly 40 years and he is my go to guy when electrical problems beat me.

The fact that it was hard to start on LPG before the dissy is an issue to resolve first. Weak spark and LPG are not good combinations, usually lead to backfires etc. Put a spark plug in one of the leads and ground it. Check the strength of the spark when in this no-start scenario. Should be a nice fat blue one. What this will establish is whether the coil is giving proper output. LPG needs a good spark to burn. If it is fine, you will need to look at the LPG system or maybe timing.

There is a simple starting point for you. (no pun intended)

Have fun!
