Ford focus fault code p2263

Hi
A flashing glow plug light could be a number of things it needs to be plugged in to a diagnostic machine to read the fault codes
Hope this helps Nick

Diesel will run if you have electricity and good compression. If you have no fault codes on the dash and everything is fine it should run. If you are starting it with a tow rather than a bump have the compression checked, have you got the correct oil and enough of it.
RIt may be that the glow plugs do not warm up, you may have changed the plugs themselves but is the circuit that supplies them functioning. I had a Laguna that wouldn't warm the pluds because the harness that distributed power to the individual plugs had a break before plug 1, changed this and bingo!. You should run a full test on the glow plug power. (Having said that , the fact that it does not start when warm indicates that this may not be the caude of your problem.
A compression check is also advisable if you get no joy from the glow plugs. If you are low on compression have your timing belt checked , it is possible it has jumped a little. We had a peugeot that jumped, it still ran, did so for six months , but you could hear the valves hitting the pistons. It would run but not very well, it would not accelerate very well maxing out at 55mph. When I say we, I mean a member of the family I hasten to add. I advised that it be checked out but to no avail. Eventually it was taken to have the head replaced and carried on fine for a couple of years , he had a lucky escape. Have the timing belt checked. Also, have the fuel pressure checked at the manifold, should be around 490-45psi. If it is not have the pump checked make sure the fuel filter is clean, the air filter must be clean too.



For a diesel to run you need duel, air, electricity, the fuel ignites (slowly) because of the compression process, the glow plugs initiate the engine start and then, as the engine warms up, the residual heat helps the ignition process. This is why I am dubious about the glow plugs being the cause, if the engine is hot it will normally run.
There are any number of possibilities. You will have to run through them systematically.
1 glow plugs
2 compression
3 fuel supply
4 air supply
5 compression
6 timing



Also, have the OBD scanned for error codes

GOOD LUCK

An engine cannot run at 3000 RPM if it is not getting a large volume of air from somewhere. I would be looking for a large vacuum leak - possibly even an intake gasket leak.

Crank sensor or engine speed sensor is faulty.

Fault:
Irregular power loss on accelerating
The speed of the engine is limited till 2500rpm
Frequent loss of crankshaft position sensor signal

Cause:
It is caused due to leaking from thermostat housing into crankshaft position sensor harness multi-plug

Remedy:
Check and clean the crankshaft position sensor harness multi-plug contacts. Rectify the engine coolant leak from the thermostat housing if found. Take a note of the engine coolant level and monitor it for changes, showing a leak is indeed occurring.

You have to check the computer for fault codes; the problem is likely caused by a faulty sensor. Take the car to autozone, they'll check the codes for free

It means the turbo/supercharge boost system is malfunctioning.
Have it checked.

run engine codes, had same issue once before it was bad computer good luck

it sounds like you have a stuck IAC, Idle Air Control Valve. It meters air in when the throttle plate is colosed (foot off gas).

Autozone can scan for fault codes for free.

May just need cleaning. Try that first.

Idle Air Control (IAC) Valve —2.0L SPI Removal

1. Disconnect the idle air control (IAC) valve electrical connector (air cleaner outlet tube removed for clarity).

1. Remove the IAC valve.

1. Remove and discard the IAC valve gasket.

rpm limiter sensor or the vehicle is in limp mode
have the fault codes read to find any faulty sensor , then use a scan tool to reset the ECM

Your vehicle's computer system has self-testing capability. When the computer senses that there is a problem with some of the components it stores the correspondent trouble code(s) in its memory and lights up the "Check Engine" or "Service Engine Soon" light to tell you that there is a problem. There are test that will need to be done depending on what codes are present to determine the proper repair.
