That was going to be my next step dont have any spark plug tester so I was just going to clip the timing light to each lead and run it up to speed. Going to connect a led to the injector pulse wire and check that it doesn't do anything odd. Maf will be easy to test with a multi meter. Tried to...

Crower 50229 from v8 tuner. I do rate the cam, when the engines cold at least. Suits 4x4s well not a high revving thing, works well from low down.

100% tested all the values and reading at the ecu plug, also got a diagnostic tool

Yep, tried another ecu. No different. The old cam followers looked ok and none of the cam lobes were shot, engines only done 64k just fancied abit more poke and now I wish I'd never bothered!!!

Really weird I know!!! sounds and acts exactly like I've lifted off the power, but I haven't. I'd have thought if it was fuel cutting and it was still sparking it would pop and bang but if the spark stopped it'd just stop...like it does in the vid

Interesting. I did read similiar on this forum. The place I purchased the cam say its a straight swap, no stiffer valve springs no need to machine anything. They also recommend roads lifters which I've fitted. As I said before I'm going to speak with mark Adams regarding a re chip. He must have...

Thank's Chaps. was the lift pump!!

Those 3.8's are rare, don't blow it up!!! Sort out your timing buy some new ht leads/cap and rotor arm and it'll probably be fine

Now when at full running temp after about 25 min driving. Doesn't pull aswell through rev range, my foot is flat the whole time ( when it's revving up anyway ) but the engine just seems to stop running. It goes quiet and revs slowly drop. Revs stay up but it just seems like it's coasting...

I put these up before on a previous that but that thread vanished so... DISCOVERY V8 CAN REV.MOV - YouTube When engine is warm but not hot, been running for about 5 min. Engine picks up fine, revvs freely, pushed hard will ding the limiter...all is good in V8 land!

Be interested to hear what other stories of cam changes you've heard? When it's cold it pulls noticebly stronger after the cam change but that only lasts until it gets upto temp!! Did check the rotor arm and dizzy shaft. I take it you mean it pulls up the shaft and pings off the...

It's just sort of stops at 3000rpm. Foot flat to the floor and the revs just stay at 3000 no hesitation, no missing just stops. Will go higher in neutral but will not rev freely past 3000 even then and will only get to 4000. Won't hit the limiter. When's it's cold and I give it some beans it...

Already change that. Also checked the resistance at the ecu back to the coil just incase it was a trapped wire and all is well. No codes on fault code reader either

Yeah it's running but I've got the same f-ing not revving past 3000rpm problem. I've lost all interest in it now this has been going on for months.

Electricity will always take the easiest path to ground. Worth checking the earth straps around the engine bay and ignition amplifier. Try another dizzy cap if you have one too

1 tank 1 month!!!! You must use it once a month then!

30 seconds... I was doing about 5 with the plugs out, didn't want to burn out the starter!! Also looked into mega squirt but I've been upto the windscreen in water with just the use of silicone on ignition parts!!

Yep. Getting a nice blue arc. Whether or not it can do that while being under compression is another thing

I'd agree it does seemed flooded I can't tow it as its an auto. I did try the plugs out and cranking but I'll try again tonight. I'll heat up the plugs before I re fit them. How long did you crank it with the plugs out?

UPdate. It's got spark and probably did all along but it still won't f-ing start. Doesn't even catch or backfire or anything, just cranks. You can smell fuel and the plugs get wet after a while. Tried a set of new plugs and still nothing. I'm thinking but i hope it's not now going to be down...
