Ford 2.0 DOHC EFi starting problem - Ford Forums

Hi,
I have a '93 Ford Sierra GT, 2.0i which has starting problems:

When the engine is cool it starts 1st time, every time :) but when the engine has been running for a while starting becomes a real problem. It turns over soooo slowly, as if the battery is flat. A number of garages and local mechanics recomended a new starter motor, which I replaced with no change :( I changed the battery too and still no change :(

I just don't know what else to try, please help

Hello and welcome

My rover did a similar thing but that was the electronics messing with the fuel metering when hot, not as you seem to be suggesting and the engine cranking slowly.

Thanks :D

It seems to be one of those problems where when you show someone it doesn't happen :/

Going to yet another garage tomorrow to get a... well I dunno how many now... opinion

Hi Memran. Sounds as if you have replaced the 2 most likely probs.Does the starter have the solenoid as part of it or is this a separate item placed elsewhere on the car. If not the solenoid then I would check the cables and the connections including esp the earth. I have to say normally starting causes the most trouble when cold.

Solenoid is built into starter (I think)...

The fact that it starts bad when warm is whats so confusing.

Thanks for advice... 1st thing in the morning I will check all cables etc :)

Well it seems that it was the battery after all! What are the chances of replacing a bettery with such a similar problem?

Anyway, I got the battery replaced by a BIIIG one now (biggest that I could fit in) at no extra cost so im happy :)

I'll post again when I find if its fixed the problem

Thanks :D

Now that IS a tricky one.

Err that didn't come out right at all... I guess I should proof read :s4

Apparently one cell in the battery was faulty causing the voltage to drop to less than 8 volts when starting. This resulted in nearly 500 Amps being pulled!!

The thing is, I don't see why this would be heat-dependent. But at least the new bettery is rated for 600 Amps (old one rated at 320 I think) so even if it does happen again, it should have enough to start up.

Still to replace the battery with another faulty one is a bit of a trap. Lets hope it works out this time.
