Head Gasket Finished....Now What?!!!
Ok guys, here's a new one for me...hopefully someone out there has experienced this and can shed some light on what I need to do.
2001 Disco 2, 99k miles...replaced head gasket, had the heads machined and put new seals in, cleaned everything I took off and replaced water pump.
Now it won't start. I expected it to be rough until the new fluids circulated, but it won't turn over at all. It feels ( and sounds) I have reversed the plugs, but I've double checked and it's hooked up right.
After several attempts at starting, it pulses the starter and the Amigos are lit up. Codes are:
1. 0734 - Gear 4 incorrect ratio
2. P1668
3. P0560 - System Voltage
....two days later....
Charging the battery allow the disco to crank right up. I cleared all codes and drove around for 20 minutes or so. The new codes are:
0171 System too lean Bank 1
0174 System too lean Bank 2
0332 Knock Sensor 2 Circuit Low input Bank 2
Should I replace the MAF or are there other suggestions?

ok, charged battery...now she cranks right up. Sounds good, runs smooth.
now I have the following codes:
0171 System too lean Bank1
0174 System too lean Bank 2
0332 Knock Sensor 2 Circuit low input Bank 2
should I replace the MAF? Is it safe to drive?

I was joking that that might be the case.....Thanks for the input. I have cleared the codes and we'll see what happens.

okay...the codes are repeating after being reset...I'm ok with waiting a little bit on those (you know, clean engine and all) However, when the truck is cold I'm experiencing some hesitation on acceleration. Any thoughts? I used a semi-synthetic 10w-40.

the mechanic at work thinks the hesitation in acceleration is the O2 sensors. Anyone agree with him? Do I need to replace all four or is there a way to determine which one is bad?

Thanks....
On Mike's advice, I replaced the MAF and now all is well.... no codes, no issues, runs smooth...
Thanks everyone, especially Mike!
