Problem starting ford fiesta XR2i 1.6 8valve.
SegaDude
I have a problem with a ford fiesta XR2i, which is a 1600cc 8 valve
CVH Efi model, 1991.
It has a k &n induction kit, the engine is standard as far as I know.
It has a alarm and immobiliser fitted but was fitted when I had the
car so I don't know what make it is.
the problem is, that sometimes i can't start it from cold, or
sometimes when its warmed up. Sometimes i can start it, if going out.
But when i restart it to come home it wont start, and this is when the
engine is still warm or not long been turned off and sometimes it
won't start when its cold. The starter turns over ok, and battery is
fully charged.
Sometimes, It will start after I put car in 1st gear and the starter
drives the car forward and sometimes I have to do it in reverse gear.
After i changed back to neutral sometimes it will start after doing
the above, but not always.
I've checked the connectors in the engine bay for all sensors, but
everything looks ok, the spark plugs aren't wetted either, and have
the brown looks that mean the engines in good condition. No smoke
comes from exhaust at all.
I thought at first it may be the fuel pump, but I don't even know
where it is to check. Then i thought it may have been an immobiliser
problem, but thats working ok.
Any answers are most welcome.
thanks for your time.

When you first turn the ignition key the fuel pump should activate for 5
seconds to pressurise the system.You can easily hear it buzzing if it's
working. If you can't hear it you have your answer. The pump is in the tank
AFAIK.
If the pump is working you need to crank the engine and check for a spark at
the plug leads.

If its not working, the pressure thats meant to be held in the
fuel system overnight won't be there .... or maybe its seeping allowing
the pressure to fade away over several days (or even allowing air to get in
via the return line).
That would cause the poor starting sometimes when cold.
As for hot ... you need a bit of residual pressure in the fuel system
to prevent fuel vapour from sitting in the fuel rail just over the hot
bits (engine).
No pressure = no liquid fuel = wierd starting.
Check fuel pump fuses/relays as well .... think of age related corrosion
on fuse/relay terminals.
If its anything like my old 520i, if the fuse feeding the fuel pump fails,
it
will start as there is a line from the start position directly to the fuel
pump,
but as soon as you let go of the key the fuel pump feed goes via the
(faulty)
fuse.
So it will start, then stall when you let go of the key.

Just IME...
I had a 91 Orion with the 1.6 CVH. It did this.
It was the battery and/or the starter.
What happens is that the starter pulls the battery voltage _really_ down.
This means that the ECU or injectors won't fire up properly. This is (from
what I've heard) a very common problem on the CVH EFI engined Fords.
It means that the engine doesn't get spark and/or fuel.
This is even though the starter was turning OK.
I had a _total_ nightmare of a time until I replaced the starter, and then
it behaved (virtually) impeccably.

reference.
Pete was right, it was the fuel pump, I managed to locate the fuel
pump under neath the back seats (strange place for a pump), and
wiggled the connectors about, and when I turned the key, I could then
hear it buzz, as it didn't do this before.
I'll leave the back seat off for a while just in case i have to wiggle
it about again.
Thanks for advise.

If there isn't one take the crank shaft position sensor
out (connected near the front of the gearbox) and clean
it.
I had the same on my fiesta
