    5.3LS won’t rev?

    I have a code reader but that’s about all it does, it has a live data option but none of the numbers change, that’s a walmart obd2 reader for ya

    5.3LS won’t rev?

    Is there a cheaper alternative? I don’t really have a will to spend several hundred dollars to see what’s going on, after it’s all good and well I’ll never use the tool and usually I’m all for new toys

    Fuel pump pushrod won’t slide into block

    I put grease on the rod and it goes around 1-1/4” in, I can’t see it all from one angle, I laid under the blazer to see the bolt missing, I did from above to see the rod not going in. It’s got a 6” lift it sucks to work on honestly. Say that is the culprit, however would I go about fixing it?

    Fuel pump pushrod won’t slide into block

    Me aswell. Main thing keeping me from getting this unit running. The electric pump won’t pull fuel from the tank anymore

    Mentioned bolt in first post, it’s MIA. I’ve never experienced this so I have no idea

    Fuel pump pushrod won’t slide into block

    It only goes a little over an inch, I put a 3/8 drive 6” extension and it slid right in without issue. It’s just a hair and a half smaller than the rod

    5.3LS won’t rev?

    They claimed to not have done many, I don’t know how to tell what has or hasn’t been done but I’ve got the vss installed but it wouldn’t really put out anything unless I’m moving? I couldn’t tell a difference in before or after installing the vss other than I need a longer speedo cable or...

    Fuel pump pushrod won’t slide into block

    So I bought a K5 blazer a month ago and it has not moved at all. It has an electric pump but it lost prime and stopped pulling out of the tank. I gathered all the stuff to throw a mechanical pump on and I can’t get the rod to slide in? The bolt in the front is mia, I took a 3/8” 6” extension and...

    5.3LS won’t rev?

    Yes tuned for an 8k pulse. Speedo cable connects to it. Speedo doesn’t work I have to redo it but the sender is on fine but I need to re route my Speedo cable so it reaches

    5.3LS won’t rev?

    I’m running a 4 speed manual, people have been 50/50 whether or not the vss was needed. It’s a Dakota digital pass through sender on the tcase. Never had any codes related to it. I’ve got a code reader but that’s about all it’s good for, I’d like to get a fancier one

    5.3LS won’t rev?

    It had a 350 that was getting ready to settle down, it would’ve cost the same to build a decent small block as I’ve got in this swap lol I’m under ~2500 and I replaced a lot more than just the engine. I’m all for a 350 but I needed this truck to be reliable and get decent fuel mileage/power...

    5.3LS won’t rev?

    I did not get around to grounding pin 34, but I did finish the vss and cut the exhaust back off and just clamped some 90° bends on coming out under the door. Drove all around the yard without issue, revved the truck and then it cut and started doing the issue again. Does this sound like I’m...

    Yolo, I’ll ground both pins and see what happens

    5.3LS won’t rev?

    Would that you think make the truck always think it’s in park or neutral though and make the rev limit really low? I don’t plan on revving it really high I just need it drivable

    5.3LS won’t rev?

    I’ve read so many different forums about this and everyone seems to lean towards abuse mode. Revs to ~1500 and just stops then revs back up etc so on. I’ve talked to my tuner and he said he didn’t touch anything related to it so I sent him a couple forums to inform him of what people are saying...

    5.3LS won’t rev?

    The truck is a 4 speed manual with all the auto harness stuff cut off. I grounded pin 32 on the blue harness as per request someone in the fb group with no benefit, I’ve also read to ground pin 34(both pins are PRND related) I might try that but I don’t want that to cause it to think it always...

    5.3LS won’t rev?

    The code does come back but just observing around the #4 coil pack everything seems fine. The coil jiggles in the bracket but that’s the only thing separating it from the other seven. I followed the wires from the o2 sensors up to the maf and it all seems fine. The only code the truck is showing...

    Goodwrench crate engine smoking from passenger side exhaust

    Truck was apparently parked for the reason of flooding. I never did get it fixed I traded the truck off for a one owner k10 and a k20 frame, then traded the k10 for an 82 gmc c30, then traded the one ton for the 83 K5 blazer I still have lol

    5.3LS won’t rev?

    A guy in Murray did the harness, the wiring around the o2 sensors looks fine, the grounds seem fine, I also hopped on that Facebook group and a couple people mentioned abuse mode, I’m cutting the exhaust today since I’ve got all the pipes now and I’ll see how it acts being just manifolds and...

    5.3L LS checklist with part numbers

    It’s after market but the back where there’s usually a switch, has nothing, cheapo Amazon tach for ya I reckon. I have another one I can swap in later I’m focused on getting it running correctly currently.

    5.3LS won’t rev?

    @gmbellew its cable, with full range of travel @Ricko1966 po354 would be the second one on passenger side right? That cool is loose in the bracket if that matters? All the others don’t move but that one jiggles. I observed my o2 sensor wiring after the exhaust and it all appears fine along with...

    5.3LS won’t rev?

    I ordered 2.5” pipe and I’m going to redo it just incase since the manifolds have 2.5” pipe. I just don’t understand what all of a sudden caused this issue. It will rev fine to 1500ish then just cut off. I can hold it to the floor and it repeatedly just bounces up and returns to idke

    5.3LS won’t rev?

    The MIL came on with code po354, could that have any correlation with the issue? I’ve ordered a complete 2.5” exhaust kit and plan on redoing the exhaust. I just don’t have any idea why it’s all of a sudden an issue.

    5.3LS won’t rev?

    The truck ran fine before getting exhaust done other than occasional idle surge. I just had them connect the existing exhaust on the truck to the manifolds (2” pipe) and apparently that’s too small? I’m looking into going to 2.5” pipe since it’s got dual exhaust the whole way back
