RRC won't run!

[MuddyRangeRover]

Ok, so finally we were able to put the engine all back together.

Gave it a once over, and turned the key. Now, before I continue, I will mention that I was having problem swith my fuel system. My Fuel pump wasn't coming on before. I gerry rigged it to the rear lighter, and now as soon as the truck is put in position 2, with the fuse for the lighter in, i get fuel. Now this will be addressed, but we were hoping to run the truck first, and then figure out the rest.



Anyway, as we turned the key, the truck turned over, and after some time it fired up. It was LOUD. Lots of ticking/knocking could be heard. I hope that that will all adjust itself once properly lubricated. asnyway, after running it for approcximately half a minute, we shut it off. BIG mistake. we haven't been able to start it since. It fired up briefly 2 times, and then got flooded. Over night I removed the spark plugs, and cleaned them and dried them. This morning I was able to get the truck running briefly with quick start. Couldn't get it running on its own.



Here is what we checked:

Timing is good. TDC seems to be good. Rotor is @ 1 when 1st piston is at the top.

Injectors seem to get power to them. We used a meter to check the plug.

We obviously get fuel since you could smell it and hear the fuel pump.

We have spark.

2 other things.

1) There is 1 wire, that splits into a male and female conector. It comes out of the bunch of wires that attach(two loop connectors) to the alternator. Couldn't find where they go? Anyone?

2) mY tach was not working when the truck was running.



Any help would be greatly appreciated/

What kind of fuel pressure do you have?

I have no idea. How do I check?

Ok, so last night, I did a few things that people were mentioning.
First of all I hooked up the Fuel pump back to its OE plug. It works. Thats for sure. You can hear it start buzzing when the truck is put in the #2 position.
I also used a voltmeter to check some of the fuel injector plugs. Can someone tell me what the reading is supposed to be?

I did the pass side while cranking;
#2 had a reading that jumped from 0.20 -0.43
#4 had a reading that jumped from 0-23-0.48
#8 had a reading that jumped from 0.25-0.70ish
Is this normal? I was in the 12V option on the volt meter.

Also, some time ago I messed with the TPS sensor, i didn't know you were supposed to put it back and set it properly, I just slapped it back. Could that interfere with the truck not starting?

I managed to flood it again after some trying, because when I was pulling the plugs, they were drenched in fuel. i am currently letting it dry out before attempting again.

I also swapped in another AFM,(I have 3).

How can I recheck the timing myself?
Anything else I need to check?
Could this be a bad ignition coil?

To check the fuel pressure you will first need to depressurize the fuel system. Then hook up a fuel pressure tester (in line) at the outlet of the fuel filter. You should expect 2,39-2,67 kgf/cfm2 ( damed metric) according to the manual. The TPS is non adjustable, it could however be cause of a hard start condition, or overfueling/flooding. Test it or replace it with a known good TPS. If you have just replaced the spark plugs it will be hard to tell but generally a leaking injector will cause the plug to be sooty. Do you still have the old plugs from before the overhaul ? I have no idea about the voltages given, do you have the manual on CD for the RRC NAS ? A invaluble resource. Seems to me that the timing is in the ballpark for start-up. It can always be a bad coil, but if it has failed premature, then you need to look into why it failed. Something is a-miss! What has happenend to enable you to run the fuel pump successfully on the OE harness now when before it would not run at all and you had to hardwire it the lighter circuit? Hope this at least points you in the right direction or gives you a few ideas as to the problem.
