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?

 

Low voltage? Try topping off the battery, or jumping.

 

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?

 

It's clean. Rovers don't like being clean. The knock sensor I'd check the wire on, but after a few miles, the 'system too lean' errors may just go away. A lot of us find the same codes when we do the Seafoam cleaning.

 

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?

 

start with the 2 front...

 

Thanks....

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

Thanks everyone, especially Mike!
