LS Swap Crank No Start What Your Mistake is

[@WillHorne222]

Man everytime I needed help with my TJ ls swap, I'd type it into google. You were always the number 1 solution. All the way to the end. Thank You for taking the time to do these videos.

[@TestDontguess]

i'm glad I was able to help, I tried to make the most documented swap there was in a TJ covering every little detail of my experience

[@oldcarguy700]

What pin needed power and what pin did you tap into? Thanks

[@00Blackgreen]

Damn you good brother I have watched 1000 videos maybe 20 literally to figure out this situation and I paid attention to yours and detail and fix my problem. God told me come back to your page lol

[@ThirstySpoon]

Thanks for posting this video. It totally fixed me no start/spark problem.

[@jamesrichard4782]

It got my LS swap started as soon as I grounded that wire. Thanks for the help

[@josearagon2276]

What pin on computer needs the juice while cranking and where did you get it from you diddnt show that mines cranks no start lq9

[@johnnygarcia71]

Thank you for your help I noticed on mine the computer needed to be grounded I bought car and computer was underneath the seat so the gas pump and was not getting spark as well I noticed when I would move computer the relays would make a clicking sound so I put a ground wire on computer and hold it down then I had my son start car then it started right up hopefully this helps someone else out Everyone Have a Great Day

[@donaldthieleman]

Nice. Gonna try this weekend. Thanks 🙏

[@jameerchavis6135]

Are you DBC red/blue connector if so what pin is that on the pcm?

[@parkerboggess2963]

what wire did you plug the tester into?

[@enoughofthemasksalready3881]

I have no spark... I do have power at coil packs.. kinda stuck at tg moment.. oh and that hot wore while cranking .. I hooked up for the moment straight to battery.

[@snowman6512]

by chance do you know how i would find a switch power on my 1988 chevy caprice?

[@keciawilliams3448]

Was that coil wire pink or red?

[@sixtolopez2712]

Hello I have the same problem engine rebuild it turned on before I pulled it now it won't start it has ground and voltage just no spark

[@milbrooke]

I have a similar issue…crank, no start…LS1 (going in a 91 Camaro RS). I checked spark and have spark on ONLY cylinder #1! Any ideas? All plugs, wires, coils, and injectors are brand new. Thank you.

I had my c10 running it died put in tank pump setup in still won’t start but will backfire

[@kingcity4]

Where did you hook your tester to

[@Derik64]

So I have the exact same problem. Its a vortec 5.3 engine in my Colorado. Thing is I bought it like that and I've been driving it with no issues. The other day I was driving home and hit a dip. Nothing hard but its a good up and down, like a roller coaster. As soon as the truck bobbed the engine cut off but all the loads were still on. So I don't know if I shook something loose or maybe even worse my top post battery grounded on the hood when it bobbed and killed the ecu since my truck apparently has two different computers. No spark. Cranked with some carb cleaner going into the air intake and nothing, not at all. Any ideas???

[@briancooper2216]

Same thing happened to me did you figure this out

[@Derik64]

@briancooper2216 I blew a fuse. The wire harness was jammed up behind the engine and grounded out the fuse for the starter. I cant remember which fuse but I know that I just assumed that it was fine only to find out later it was blown. Had to remove the intake and move all the wires out. Some were rubbed and frayed. Cleaned them up, did some housekeeping with the wires, put a new fuse and it did the trick. I kept blowing fuses before hand because I was being lazy on the housekeeping of the wires.

[@Auditinginthe405]

hey man. set your meter to what? this is such a vague video as far as what to do diagnostic wise.

[@TestDontguess]

It’s not vague, if you can’t understand what’s going on and how to use a meter this diagnostic is beyond your pay grade.

[@Auditinginthe405]

@@TestDontguess this is youtube, just wanting to test the circuit didnt think I'd have to bust out electric books from ten+ years ago. thats why I came to KZbin asshat

[@dontworry6256]

I connected mine to the battery and still same issue just crank

[@khg_7]

Me too

[@frankguerra3314]

That's what's wrong with my ls..I put it in another truck an it won't start. I check the grounds.an I change the crank cam sensor....

[@miketoews77]

I'm having the same issue did a frame swap on my truck, which wire did you connect to get it running? I'm horrible with wiring I've watched the video many times. Please help

[@TestDontguess]

You need a wire that is 12v while cranking to work

[@pimpin4wayzofficial]

You’re running that pink wire to straight battery?

[@TestDontguess]

No….. it’s ignition on while cranking

[@pimpin4wayzofficial]

It’s coming from ignition on while cranking and in order for it to receive 12 bolts at all times where are you hooking it up to

[@isaacgreen1599]

Hey what’s up bro how did you get your rpm gauge to work on your LS swap

[@leroybarnes2641]

You have to set the switch for 4 cylinder

[@MrCanlawnz]

Glad you got it running. Good info for Mechanic but for an average Joe doing it's 1st swap bad explanation. No steps in what tools to use which wire coming from what. But I understand you don't get get paid for this. Maybe you can do another video step by step... only if you want to lol

[@J2A61]

@@jonherrington5274 the problem was the company didn’t do my harness correctly, after sending it back 2pr 3 times it finally started and runs great check my channel and you can see for yourself. I do want to say that dealing with an out of state or town was a big headache I just happened to go to my provider’s city, and I actually pulled up to his shop and he was actually working on my stuff. So out of town companies do business at your own risk. Me personally I will never do it again

Yeah that is great and all but you kind of skipped over how to do it same problem I run into every video
