Question out of curiosity... An observation..

Does a low battery voltage result in "cold start problem" like symptoms?

After sitting so long while we worked on it, even though for most of the time it was disconnected, my battery has almost had it and needs a charge, the car starts, but only if you lift the injector plate and give it a helping hand (fires up straight away).

Otherwise, the thing tries to kick over, won't start and the battery fades away. I would have thought that if the battery didn't have enough juice, even if you lifted the injector plate, it still wouldn't start.

If the car is warm though, the thing starts up fine (needs a little coaxing with the hand throttle though).

I will be charging the battery tonight, but I was curious as to whether cold start like problems can be attributed to batteries with not enough voltage? I am kind of ignorant of the way the CIS system works completely.

I haven't had cold start problems before, and I can't see why something would stop working now (though I guess they do?)...

I assume its just the battery.

Proper fuel pressure indeed is required by the fuel pump, which is controlled by the battery. If your battery drops enough voltage when cranking (it will drop some no matter what), then you could not be receiving the proper pressures at the CIS system.

Answer? I'd say it's possible...

So does lifting the injector plate hard start it so to speak?

And does the car being warm help pressures in some respect? Or could I be looking at a newly cropped up cold start issue?

I will charge the battery and see how she goes anyway.
