    '94 350: good cold starts, struggles to crank when restarting or still warm

    Sorry for such a delay on this. Been a busy winter. So I have yet to swing thru autozone for a load test. And I have not done the voltage drop test from battery to starter. But readings at the battery terminals Truck off: 12.53V Running: 14.14V Cranking lowest read drop: 8.38V Sent from my...

    '94 350: good cold starts, struggles to crank when restarting or still warm

    I need to get an assistant to check voltage drop at crank. I grab the voltage while off. And the battery was load tested at AutoZone back in June, listed fine. Sent from my SM-G981U using Tapatalk

    '94 350: good cold starts, struggles to crank when restarting or still warm

    Welp....both cold and hot starts sounded strained this morning. But it is 24° outside. Time to get the battery checked again. Safe to assume that months of heat soak starts can damage my battery's performance? Sent from my SM-G981U using Tapatalk

    Ya I threw it on a bolt front lower passenger side of the block. The bolt that goes thru the bottom accessory brackets into the block. Figured get it as close to on the block as possible Sent from my SM-G981U using Tapatalk

    '94 350: good cold starts, struggles to crank when restarting or still warm

    Just waiting on parts to come into. Between that and deer season I'll find time to get the truck on the lift. I plan to: -remove starter and clean mounting surface to engine block -remove all grounds and positive cables -clean all grounding spots -install starter heat shield -new knock sensor...

    '94 350: good cold starts, struggles to crank when restarting or still warm

    Agreed. I think I'll install a factory set of cables. Then add some additional grounding cables.

    '94 350: good cold starts, struggles to crank when restarting or still warm

    Or what do most do? Stack lugs on a bolt? Custom cables? Or factory cables and just add the big 3 on top of that?

    '94 350: good cold starts, struggles to crank when restarting or still warm

    Schurky, when I get an assistant I will do this! But for now I have planned a heat shield, replace battery cables, and clean up those connection points Are all these heat shields pretty much the same thing? Also, thoughts on these battery terminals for GM side posts? The theory seems nice...

    '94 350: good cold starts, struggles to crank when restarting or still warm

    So I'm going to pull all the battery cable and rewire the truck. I never did that properly. Also I'll clean up connections. I'll have to look for a heat shield And what is everyone's thoughts on the Sender wire. I don't get how that needs to provide anything but a trigger signal for the...

    Or maybe high resistance in a wire to the starter? Sent from my SM-G981U using Tapatalk

    Any way to truly test if it is heat soak? Sent from my SM-G981U using Tapatalk

    No coolant loss. And wouldnt that be a constant start issue. Not just warm starts Sent from my SM-G981U using Tapatalk

    '94 350: good cold starts, struggles to crank when restarting or still warm

    Timing is at zero...maybe 1° if anything. It's damn near center of the big notch. Shut it off. Went to restart it while sti at base timing, still hard to get that first 2 crank rotations. Rehooked the tan/blk wire. Floored the gas pedal and cranked it. Didn't help to start the motor...but...

    '94 350: good cold starts, struggles to crank when restarting or still warm

    The starter isnt a year old. I can crank the motor easy, shut it back off, then struggle to restart it. Otherwise I was thinking heat soak originally. I plan to replace the knock sensor being the easiest think to start with. Then verifing base timing. Sent from my SM-G981U using Tapatalk

    '94 350: good cold starts, struggles to crank when restarting or still warm

    1994 Stock TBI 350 w/4L60E So this summer i noticed that if i shut the truck off to go in and shop it would struggle to turn the engine over when i got back in, like it was fighting some massive compression now. Once it got to the 2nd crank rotation it fired right up. If it sat for 2+ hours it...

    Tcc shake

    So heres what lead me to today. Drove to a concert 2 weeks ago, while parked noticed a rattling with A/C. Poked around figured ac compressor. Drove home with ac off. Went to look into it next day, sound is more from bellhousing and now hear it at idle regardless of ac. Drop the trans (4l60e)...

    Brakes flash with right turn signal

    Was able to find a turn signal switch to swap out. Fixes the issue. The old one was shorting out into the hazard line Sent from my SM-G950U using Tapatalk

    Brakes flash with right turn signal

    Ok, i hate electrical gremlins. Replaced the turnsignal harness in the steering wheel earlier this year. After awhile the cam wouldnt reset the right turnsignal after making the turn. Now with the right turnsignal on it flashes all my brake lights. (Fronts good). If i apply the brake it stops...
