"It comes out the vacuum line, not the regulator itself. " That just violates the laws of physics. Which end of the vacuum line is the fuel coming out of?

My friend said it came out there only when he pulled the regulator first because that's what he was told to be by another guy. The guy being a mechanic of some credibility. Prior he pulled the vacuum it didn't spray fuel. I erred because I caught the butt end of that.Originally posted by 86FieroSEv6 View Post
The fuel pressure holds at around 52psi. Initially it jumps to 60psi. holds at around 55-56, a few minutes later drops and holds around 52. I think that's pretty good from what I've read.Comment

I seen it flow from the vacuum line (the line atop the regulator.) it was because the regulator was pulled. This was a suggestion by a mechanic friend. It's not my truck, it's a friend. I met up with him to help him and provide a means to scan his truck.Originally posted by 86FieroSEv6 View Post
The truck is at my house now. It drove here fine.
Is it possible that two coil packs are bad and it's flooding the whole engine? Thanks!Comment

Checked fuel pressure, it was fine.
Checked that all coils had spark.
Replaced plugs and it works great now.
The plugs in it were those E3's. 1 of the plugs looked damaged. Not sure if it could have caused the issue or not. Or maybe the O2 sensor was bad. I don't know, but either way, a set of autolites and that was that.Comment

I get AC delcos most the time. The autolites seem okay. In any event, they were the cheapest. I believe they were recommened for the 3500 in a Malibu. Or maybe they lasted longer than the AC delco. Anyway, I think they are decent plugs. I have no opinion on the E3 since it's not my truck.Originally posted by robertisaar View Post
My friend said he's never buying those fancy plugs again. The truck runs way better now than it ever has. I think that says a lot against the super fancy plugs.Comment

they're just like the GM DIS coilpacks: NOTHING aftermarket beats them for either durability or performance.Comment

E3's are junk man, put the Iridium's back in there.Comment

They are nice. The ones on that truck are the orginal, I believe. The spark plug wires are factory wires too. Whether orginal I do not know. But if they are original, they have 231,000 on them. Or so this guy at a shop said they were factory because of the logo on them. Apparently they don't come like that anymore. Again, whether true, I do not know. But the sucker sparks on all eight wires. Seems like a good design. Spendy to replace all eight, but if you isolate the bad pack, it seems pretty cheap.Originally posted by robertisaar View Post
That's what's in there. The autolites dual platinum or something like that. They were close to $4/plug. In any event, it's not my truck. It's a friends. He only got the E3's because the sales guy said it'd help clean the carbon on the engine. It's a high mile 5.3l (231,000). It's a work truck so he hauls stuff all the time. Good truck, runs great with the autolites. He said it seems to run better now than it ever has. He won't be sold on that fancy crap again.Originally posted by Superdave View PostComment

Right on. Think about it, after millions in R&D if the manufacturers thought pretzel shaped titanium electrodes were the shit, that's what would ship in their product.

I've always bought AC delco on my vehicles (at least GM.) Although, I was told the autolites were recommended for the 3500. If not true, it's best to know now.....Originally posted by 86FieroSEv6 View Post
The downside to salesmen. They tell you what you want to hear. And in this case, it hurt someone who is hurting. And this shit hurt him bad. It's junk. He knows now, carbon burning plugs is bullshit. it's a good thing really........... Sometimes, you have to live to learn. I tell you what, I'm still learning. I won't even begin to talk about how much I have into my 1,300 Alero.Comment

Autolites are platinum plugs, they are not the best thing to use in a waste spark system like ours, Delco/NGK Iridiums are what seems to last the longest.
I put a set of Autolites in my old '04 GAGT, it ran fine for a while but then started missing again. I swapped them out for a set of Delcos from my spare 3500 with 53K on them and never had a problem again.Comment

The key for GM DIS is that both electrodes need to be the same alloy. I have used good old copper core plugs with great results. They only last about 30-40k as opposed to the 80-100k for platinum, but eh . . . I maintain my stuff. In coil on plug systems you can use single platinum as the spark is one way only to ground. For a while Ford shipped out with the positive plugs having a platinum center electrode and the negative plugs having a platinum ground electrode in order to reduce assembly costs from having to use double platinum during production.

^^^ i've actually seen that on fords.... i was thinking "WTF, does ford know they're stickin half of the wrong plugs in at the factory?"
they now recommend double plats, for all cylinders.Comment

What was really hilarious was the routine I gave the Ford parts guy. Told him that my customer was hot about not being able to get the original spark plugs for his Crown Vic. Made him jump through a flaming hoop trying to explain to me that they were assembly line parts and not available for service parts. Poor guy was serious. . . . . . . . . . . . . . . I wasn't
