Title: Need help badly
Post by lebelbelshaw on Jul 3^rd, 2010, 6:47pm

I have just finished doing the head gasket on my 2 litre Scorpio 16v and it is only running on three cylinders. Some of the wiring to the coil packs was faulty but I have now rectified this all spark plugs are sparking and the injectors seem fine. I have come to a stand still as I didn't have this problem before I started.

are you sure its miss firing and not just miss timed? there are 3 marks on the bottom pulley, from memory its the left had one if you get what i mean?

are you sure the injectors wiring plugs are fully down, again from memory i think the first 3 injectors are all in one housing and the 4th on its own

What does the left hand mark have to line up with and I have check the injector there all sat on right

there should be a peg that stick out just above the bottom pulley, you may have it just off top dead (middle mark) you'll need the rocker cover and front plate off again,

also check the chain tensioner has released you need to give them a tap to free them off

have a read of this manual http://www.fordscorpio.co.uk/manual/engines/dohc16v/DOHC16VCHead.pdf

I checked all the aligment as described in the manual for the head gasket is there anything else you can think of any sensors.

theres the cam shaft sensor on the side of the cylinder head

give the fuel line connectors a check over to, ive known them to not fully locate before,

theres various vacumme hoses on the intake manifold, maf sensore on the air box

the coil packs are wasted spark so if the main unit is firing so should the plug on the lead, unless you have a break in the casing and its shorting on the rocker cover

I have just finished checking all fuel lines and sensors. I have got to the timing part and I haven't got any gold links on my chain or dots on the cam sprockets as described in the manual I also can't find a peg as described by matt above the pulley. Any surjestions

I have now sorted the timing out ( I think) as it is running on 4 cylinders. I am now suffering with a bit of miss fire and poor idle. Any tips on what to check now. I was also wondering how much the diagnostics kits are for the scoripo.

Was it working ok before the head gasket?
If so I think its just a case of checking over everything you have done or touched.

When you say you checked the sensors how did you check them?

If you don't care about ABS codes, almost any ELM-based lead off ebay will work, costs £15 or so.

I have check they have clipped in right

Does anyone know if the diagnostics on the Scorpio is obd 1 or obd 2

Title: Re: Need help badly

yep felt stupid when i realised after checking the timing twice and redoing half the wiring thinking something was shorting out oh well all done now and she is running sweet as a nut. Just got to sort out the back bumper and she will look brand new
