Headers and Spark plugs

[77ChevySharkBite]

hey guys I just put headers on my truck and also replaced 4 spark plugs on the block and when I crank it up all its doing is making popping noises anybody got any suggestions?

[75chev4x4]

I would recheck your wires make sure they are on the correct plugs, maybe got mixed up after swapping plugs.

[77ChevySharkBite]

Thank you and yeah that's what I even asked a few people cause yesterday it was fine but today it's making that popping noise

well I switched around the wires, and now the truck wont start but the backfiring sound is gone any suggestions?

What was it doing before you swapped the spark plugs and why did you only swap 4 of them?

[77ChevySharkBite]

It was running fine but in the process of taking the old manifolds off I broke 4 spark plugs

Did you bump or pull off your ignition wire going to the distributor? Was it starting when you had the backfiring problem?

[77ChevySharkBite]

No everything was fine and yeah it was starting when it was doing the backfire, when I first started the truck I heard a big pop and ran for about 5-10 seconds then died and then started it again and it kept running with a popping noise which I'd assume is it backfiring

may I add from the front of the truck going towards the dist.

I checked and fixed the one that I mixed up, I had friend tell me that there could be a connectivity issue that it might not be getting full spark could that be the reason why it's not turning over?

So the motor just cranks but will not start? Can you smell gas getting up to the carb?

[77ChevySharkBite]

Yes to both questions my friend was saying that it could possibly be my battery because it all the sudden got cold here it might not have enough amps to crank it fully.

I know it got real cold here in San Antonio

[77ChevySharkBite]

Yeah it's about 55 here so I really don't think that it getting not enough cold amps to start it would be pretty possible. Cause it was literally overnight that it got cold and I just had to buy a new battery in my car and I had the same thing happen, it was warm and started the day before and the next day it was cold and my car didn't start.

Throw your battery on the charger and see if it cranks up.

[HTX86chevy]

Mine recently broke down about a month ago.... It would turn over but never started up. Ended up being the coil. You can have the module tested at the autoparts store and the coil was only about $25 , so its worth a shot.

Okay I'll keep that in mind another friend had made the statement that if everything is fine on the truck that there would have to be some sort of resistance to prevent it from starting. And I would test the battery but I don't have a volt checker and I'm not longer at my dads house I'm at my place.

Got jumper wires? Jump it off your other vehicle

[77ChevySharkBite]

Yeah sadly enough I don't have any, but a friend of mine that has the same motor as my truck is coming over so I'm going to have him bring his over and try that.

The first link is the truck running with 1 header on it, and that was Thursday, the 2nd video is what it is doing today. Any ideas?

[JRANGER]

[77ChevySharkBite]

Yeah trust me I wish I knew it myself but I do thankfully I have a friend that's built a car from the ground up and another that's been a mechanic for about 5 years so trying to get them both to look at it to get it fixed in the first try or process of elimination

The second video kinda sounds like your starter isn't disengaging right. Hence the "whoooom"ish sound. At least that's what mine did, and why.

[77ChevySharkBite]

yeah well none the less the truck is getting a fine park and no start until I can get back on that side of town on tuesday and have a friend come help look at it, but I'm definitely going to be looking into all the options that everyone has suggested to me.
