Let's just start by saying again that you all rock!
Where in VT are you and the truck? : Brattleboro
What were the original symptoms and what are the current symptoms:
Originialy the truck ran fine - this is important because it has been suggested that it has the wrong injectors or the wrong cam shaft, which is after market, in it, but it did work when I bought it. Then it began to develop a bucking that felt like you would expect if a truck was running out of gas. Finally it just died and would not start. The first shop it went to said the alternator had died and that was the problem. I mentioned the fact that it was bucking before it died, and they said, "well these trucks have computers in them which if they are not getting enough electricity then they would cause the fuel pump to not pump and you would get that bucking." To be clear that was a non-rover shop. So, they put in the new alternator and I drove it away. It died in less then 24 hours with the same problems from before. I had it towed to DAP and they found that the new alternator was making a VERY loud noise like it had a bad bearing and I got the original shop to get me a new alternator. Then, DAP put that one in and found the fuel pump was not pumping strong, which would account for a bucking problem so we replaced the fuel pump. After that I came to pick it up and drove away, but did not get far before the problem showed back up while under heavy load on the highway going up a hill.
I brought it back to DAP and they found that it was leaking gas from a hole in the tank, which they fixed.. they also fixed the fuel sender at that point, and replaced the plugs and wires and coil. This did not change the problem.
At this point Al at DAP put in about 20 hours of his own time swapping known good parts from his truck or from test stock into the engine and driving it home and around for two weeks trying to get a bead on this.
Now, let me be real clear about something, because I sense these is weird vibe about DAP here... Al did all that work for free and knocked off a huge part of my bill ($600) in trade for lasagna for the crew lunch one day. So just so everyone knows they did all this work almost all for free because they want to know what is wrong just as much as I do.
SO anyway.... we then came to the thought that it might need a valve job, but after some work they figured the valves were working fine. Then it was decided two injectors were not firing and I needed new injectors because the ones in there are not Land Rover injectors but Bosh after market with not the right flow rate - specifically they push 18.25 lb/hr and the engine needs 24 lb/hr. So because I am broke as hell, I bought ford motor sport injectors from a guy in California that swore up and down that they are the ones he sells to everyone with 3.9 Land Rover engines. So, when they got to DAP Steve checked the part # against the Bosh injectors and found they have the same flow rate 18.25 lb/hr, and advised me against putting them in. I went against his advice because I can't afford $1000 LR injectors and they did it. Also, logic dictates that if the 18.25 lb/hr injectors worked before, and two are known to be not working, then the NEW ones should work. instead, it made things worse. Now the truck runs SUPER lean - I don't really know what this means... too much O2, against fuel? They say you can smell fresh fuel coming out the exhaust. And they say as soon as you turn it on it heads for overheating. To boot I need to pay $250 in labor for having them put the new injectors in. I mean that is fair, it was my decision, but boy does that burn when all you want is to go wheeling.
Define gets hot real fast. I have not experienced this myself, but DAP says with the new injectors it starts to overheat almost as soon as you turn the truck on.
Is there oil in the coolant or coolant in the oil - I do not know.
Is the EFI/Check Engine Light on? Also does it light up when you turn on the key lol. - It was off when I picked the truck up last and as soon as it bucked - after replacing the coil, plugs and wires and fuel sender - the check engine light came on. It was on before the problem started as well, way back when I first bought it.
We know the injectors were changed and a ecu swapped in. Were the injectors and ecu new or used. - Injectors are new Ford Motorsport Yellow tops, Al swapped in a test ECU at the shop that they keep to check with.
"As soon as I can remember the procedure for pulling codes from the ecu or find my manual I'll give you that procedure, to see what the car has to say for itself."
I can probably get DAP to just tell me what codes it is showing.
"I'm not really worried about payment. It's more about paying it forward."
Which is super amazing.
