Wouldn't run because of a cam sensor pigtail? You'll have the same issue with a carb on an LS. The ignition boxes all require a cam sensor.
So you took the top apart, cleaned it, and replaced O-rings/gaskets and it worked?
Yeah, those both sound exactly like issues you would have with a carb as well.

Point is you still need to keep the gumout handy.

Ahh. Not getting the point across. EFI adds layers of complications and expensive parts but still suffers from the same issues as a carb set up. Getting the guy at AutoZone to read your codes is simplistic.
Actually the real point is why attack some guy coming here looking for information? Be helpful and don't take yourselves so seriously.
Looks like catscratch got his answer so my work here is done. I just feel bad about telling him to go to the carb forum only to have the hate follow him there.

Nobody attacked anyone. You took it harder than the OP did.
It was never about hate. There was none. It was about the common sense of staying with a solid very low maintenance system. I, among others am glad he saw the light in this, an saved a bunch of money!.

Honestly think carbs are easy and... I've known a lot of mechanics who attack efi with just plain old switching parts (after changing the one the code reader said was faulty and it didn't fix it). As far as what Pop-n-wood said about being attacked... the first page of this thread almost had me delete my account and move on. Stupid idea, horrible idea, April fools joke, why would anyone think to do this, etc... I asked the same question on a different forum and got great answers without people chirping in opinions on how stupid of a concept it was. So ya, even though I stuck around and listened to you guys this place isn't exactly welcoming to a newb. I'm thick skinned enough to not let it bother me, doesn't mean those comments aren't attacks of some sort. I certainly get the feeling you don't want to add to your ranks on this site.

I'll be the first to admit that I don't know a ton about carbs. Clean one out, maybe change a jet on a dirtbike but that's as crazy as I've ever gotten with one. EFI is what I started with and definitely what I'll stay with. If you were building a motor from scratch to go in your 70's Datsun I'd say rock and roll do whatcha know, but you were talking about tearing apart integrated parts on a vehicle already equipped with EFI. That's like taking apart your new laptop to install a modem because your scared of the LAN. You had to expect some criticism, maybe not as harsh as it was in the beginning, but some nonetheless. This is an LS website theres tons of good info and a lot of good guys. I've learned a ton from reading on here. Don't lose faith of the site because a few people had harsh words from the jump. And no some of the newbs don't get a warm welcome, but think of it like a big fraternity. That was an initiation.... maybe you're in now! haha
On a side note, if a mechanic is throwing parts at something because he doesn't know the problem or how to fix it, he's not a very good mechanic imo.
Been working on engines for over 40yrs and (cars since I was 13) and understand where the fear of fuel injection originated. Back when it was first being implemented it was mostly throttle body injection. You didn't have the internet and you didn't have a handheld scanner to diagnose a problem and many mom and pop garages couldn't afford a $14,000 scanner at the time. So as cars aged vacuum lines (looked like spaghetti at the time) would start leaking and cause even more problems. In the end EFI was hated by neighborhood mechanics and consumers alike. It's not like it got a bad rap it was truly a crude system by todays standards. In the end many got fixed by simply swapping on a carb because it was the cheapest easiest and most understood fix.
Fast forward to todays MPFI and it's improved to the point that it's better than a carb in every way.
We have hand held scanners and the internet to help diagnose problems and the vacuum lines that looked like a bowl of spaghetti was dropped on the intake are a thing of the past.... Life is good again!
Carbs are practical in older cars and certain late model swaps but that's about where it ends. I didn't try to be rude and I don't think I was. I explained that yes a carb will work but it's far from practical and pointed out the reasons why, The only real reason to swap in this case would be fear of what you don't understand.
