    97 K1500 wont start sometimes, runs great when it starts

    If it's not even attempting to fire when you start it then it's most likely an ignition issue

    97 K1500 wont start sometimes, runs great when it starts

    Pull the #2 plug out (because it's the easiest to get to) ground it to the exhaust manifold and have someone start it, you should have a nice hard to see skinny blue spark... if it's a fat yellow spark then you don't have enough angry pixies making it to the plug so trouble shoot from there...

    '96+ Vortec 5.7L Timing Cover + Valve Cover Gasket Recommendations?

    AcDelco or Felpro are the picks of the litter for GM stuff *Also try rock auto for all you acdelco and felpro stuff, prices are usually the cheapest even with shipping but when I went through my l31 vortec I couldn't find and reputable brand name timing covers.

    350 headers

    The heat shields they put on the manifolds dont help either lol

    350 headers

    The spark plug thing might make headers worth it just in and of itself because the steering shaft on my truck couldn't be more in the freaking way of #3 if gm tried

    Brief voltage drop when releasing gas

    Could be the voltage regulator in the alternator, also it's never a bad idea to clean your ground lugs and add a little dielectric grease before you tighten them back up.

    Is it easier to put a 2002 ls out of a suburban into a 96 or 93?

    Motor mounts are very similar between those two trucks and the aftermarket is plentiful with adapter mounts and every other part to put an LS into an obs Chevy, either way you go you have to have (total guess here) a 4l80e transmission to work with the ecu on that Ls if it's the 5.3 that came in...

    Starting issues

    The instrument cluster says 14 and this obd2 reader can get voltage 2 ways, from what the ecu reports and the actual obd2 adapter measuring the voltage at the port and for some reason the option to read from the ecu is unavailable so that voltage reading is what the $20 Amazon obd2 adapter is...

    Just went on a little test drive and heres the data I got.

    Starting issues

    Once its running shes a tire killing machine and accelerates pretty well on the top end too and yes if you turn the rotor back and forth it does click but I've messed with the distributors in both my l31 vortec trucks quite a bit (manifold gaskets )and both have always had backlash like that.

    Starting issues

    On a side not as usual I got bit by the plug doing this and it didn't hurt near as bad as it should so deffinantly a weak spark and it has a red top Optima battery and 1 year old acdelco cables and it will crank for about a minute and a half before you can hear the starter start to slow down and...

    Starting issues

    The only clicking that motor does is the stupid check ball in the Pcv valve, it bounces up and down constantly but no other unsettling clicking or similar noises. This morning I grounded a spark plug on the exhaust manifold and had someone start the truck (wasn't starting well as normal) and it...

    350 headers

    It didn't do anything to my vortec except burn up plug wires so I put the stock manifold back on, I'm still salty about that lmao

    Starting issues

    It has a little backlash in the rotor, dist. Is a spectra that is 2 years old or so

    Starting issues

    Btw the motor was at 200k when I tore it down and cross hatching was visible in all 8 cylinders so that "myth" is true about these l31's, they have very little bore wear

    Starting issues

    I tore down the motor 20k miles ago (didnt touch the rotating assembly) and spent a pretty penny putting the very best felpro had on it, severe duty head gaskets, valve stem seals, oil pan gasket ect. even did the ls6 valve springs and comp retainers. Saw how pitted the lower manifold was then...

    Starting issues

    The coolant is from the intake gasket...and it had very weak spark on start up so a new coil has been put on so the next couple of cold starts will tell.

    Accessory and radio light replacement

    You tilt the steering wheel all the way down, e brake on, put it in 1st gear (if automatic trans), extend the cupholder out, pull dash bezel out CAREFULLY (it's just clipped it but clips are old a brittle), disconnect the wires going to the middle part of the bezel ie cargo light and or...

    350 headers

    Hammering (denting) clearance into headers is a good choice but that's usually for situations requiring just a little extra room, if the collector is just absolutely in the way the you're kinda sol.... put some shorties on it‍♂️. And headers on a stock 350 will yield no discernable power...

    Exhaust ideas???

    I put a borla pro xs or whatever on my 97 with the l31 vortec and it sounds a lot better that my 96 l31 with a magniflow cat back, both are 2.5" systems. Nice deep rumble that's smooth but crisp

    Starting issues

    So today I pulled cylinder #2 plug out and watched it spark on start up and it was making a big fat nasty yellow spark so I replaced the coil (along with the rotor in the distributor because it had a little burning on the tip) and a new set of plug wires because it had the originals and throttle...

    Starting issues

    I will take a look at that thank you, distributor is only 2 years old or so but never hurts to look. Yes I did and couldn't figure out how to delete the duplicate.

    Starting issues

    1997 c1500 5.7l vortec. Truck has a hard time starting if it sits for about 12 hours or so but it's not consistent, sometimes it fires right up and sometimes it acts like it's not getting fuel, engine only attempts to fire off if you let off the starter and just leave the key on. After you let...
