I have a fiesta 1.1 Mk2 reg E349 VJW with an OHV engine with Bosch breakerless ignition.

The engine was running fine, until after driving a couple of hours in stop/start heavy traffic, the engine stopped. The engine started again after it had cooled down but then stopped again after short interval.

I changed the ignition coil on the suggestion of the breakdown mechanic and the engine started straight away running fine with the car stationary in the driveway for 3/4 hour, and a two mile road test. However, it stopped again the next day only a couple miles from home, and has not re-started since.

There was no spark out of the central HT lead from the coil, so since the HT leads and plugs were new, I thought maybe the ignition module on the side of the distributor was at fault. A Ford replacement was over £200 so I bought a new intermotor part for £30, as well as new distributor cap and rotor while I was at it. Now I have a spark at each plug, but the engine will still not start. The battery turns the engine over ok and I have re-checked that the right leads are on the correct plugs. I have checked the fuses and the ignition relay are ok. I have checked the static timing and it is appears correct at TDC on No.1 cylinder, and as the engine had been running fine before the ignition problem, I did not want to add another variable to the problem, so did not alter it.

Has anyone experienced similar problems because I am running out of ideas? The car normally runs very reliably,

Ken & June

Does it h ave compression? Has the timing belt broke and what is your fuel pressure? Try spraying carb cleaner in throttle plate/carb and see if it starts if it does it s a fuel problem as you say you are getting spark. Pump may be bad. So you'll need to check fuel pressure with a gauge

Hi, thanks for the suggestion. However, the engine does have compression and there is no timing belt or chain on this OHV engine (push-rods & rockers). I took the fuel hose off the caburettor and cranked he engine and fuel pumped out and also tried squirting fuel into the top of the carb after re-connecting pipe. Again, there was no sign of it starting even with a fully charged battery. Any other ideas?

If you can check the compression with a gauge is it low on all cylinders? Or what is it? If it is low on all cylinders like 75 or so pounds it won't start and you'll need to check for the timing chain slipped. Also check to make sure that number 1 is in time although hard to see how it gets out of time by shutting it off unless a timing chain. Since this is a carbed car are you getting approx. 1/2 pint of fuel in 30 seconds? If not then check plugged filter or bad pump. But tit takes three things, fuel, spark and compression so if you are getting two then it has to be another. Are the plugs wet or oil soaked as well?

Hi, I got frustrated and getting nowhere so got the car towed to the local garage.I told them the symtoms and what I had done to try and find the fault. They dis-connected and checked all the ignition components, changed the plugs, put it back together and it started ! They adjusted the timing and road tested the car for 5 miles and gave it me back. Somehow, I don't think this will be the end of my problems,
Thanks
