2000 Discovery 2 TD5 - Wont start after head gasket replacement :(

Hey guys,

About a month ago i bought a td5 which required a head gasket replacement. The previous owner had already removed the head . I have had the had machined, installed the new gasket, and everything is back together. However i can not get this bloody thing to start!!

I suspect there is air in the fuel lines but first i would like to make sure i have done a few things correctly.

On the fuel pressure regulator (on the side of the head) the line with the clip on connector (coming from the fuel tank) goes on the top - correct??

The tacho does not register anything whilst cranking - is this normal??

I have compression. I have been purging the lines using the method where you press the accelerator 6 times with the ignition in position 2, for at least the last 2 hours!!! I have also tried starting with the pedal down. Occasionally it kicks a little bit, like it wants to start...

I can still hear a little gurgling coming from the head or the fuel line , which sounds to me like there is still some air in there. However there are no fuel leaks which i can see...

Also the M and S lights are on. And there is a wire coming from what i believe is an oil pressure sensor... looks like it should be an earth... this isnt connected. I tried earthing it out - made no difference.

Cleaned the ecu plugs too - they were a little oily, but again, no difference

any tips on how to bleed this thing better??? Any suggestions would be greatly appreciated!!!

Have you got a copy of RAVE?

If not, download it ASAP before you do any damage.

yes i have it.

just air in the system, can take a good while to get going after head gasket replacement, cranking with your foot fully down often helps get them going.......hope you have a good battery!!

All the while you can hear that fuel pump gurgling quite loudly, there is air in the system. The fuel cooler needs to fill up and air dissipated too. Each time I've had to purge I've had to re-charge my battery in between before it was purged and would start. It then started first turn every time.
Follow the rave procedure as described and allow time for the purging process to succeed.
Btw, my copy of rave says bugger all about 6 pushes on the throttle, it says to turn key to pos II and wait 3 minutes, turn off then back again and turn over for maximum 30seconds with throttle fully depressed, releasing key when it fires. Don't flood it either!
Good luck

Give it a sniff of brake cleaner to help it out a bit
