Fuel injection questions

1 - these guys are not very sure of what they are doing. Merely parts changers at best. My thought process is as of right now to make sure everything is as they say it is, see if they have hacked up the original harness, and have a look at it taking nothing for granted. I've seen the truck running and driving so I am sure that they created the problem with the engine swap.

2- I agree. Not knowing how long before they drained the fuel is scary. However a set of rings & bearings are cheap, and I plan on going through it with gaskets and an oil pump before i put it in the Dart. But that is why I really want to hear it run before I pull it from the truck, even if I swap it to a carb. I can diagnose what it needs that way. Compression test, thrust movement, timing chain, etc.

3- are you suggesting that they might have tried to tinker with the programming? I wouldn't think so because they don't have a clue as to what all the sensors even are, much less be able to plug a laptop into it

4- I'm one of the guys that rather enjoys the electrical side. I have no problems digging in and running with it. However, as of right now I don't have any documentation and will work on getting a shop manual. Admittedly, I'm more comfortable working on the new stuff as they are just easier.
