    1997 5.7L PU, p0161 p0118 p1115

    It's an extended slow/weak crank. It feels like it won't catch, but does, for now. It does seem a little better now that it's cold out than it was over the summer. Heat soaked starter, maybe?

    1997 5.7L PU, p0161 p0118 p1115

    The only one I've replaced since I bought the truck in 2015 is B1S2. I put a Bosch sensor in around 2018, I think. The other three are pre-2015, possibly even original.

    1997 5.7L PU, p0161 p0118 p1115

    The last few months, I've been trying to track down a P0118 (Engine coolant temp sensor high voltage) and P1115 (Engine coolant temp sensor circuit intermittent high voltage) on my 97 K1500. I first replaced the ECT sensor up top, which worked for awhile, but developed a bad jerk when...

    P0300 Issues 1997 K1500

    I just got done installing the upgraded MFI spider, and for poops and grins swapped the 0.060" plugs for 0.040" at Schurkey's suggestion. Cylinders 1 and 2 are still misfiring, 3 through 8 were all good. At this point, I'll probably just have to take the truck in and have it looked at. I've done...

    P0300 Issues 1997 K1500

    I ordered a new ignition coil and managed to get it installed just as it began to snow here in PA. Except for #8, which did worse for some reason, all cylinders had either the same or fewer misfires. I'll have to check the wires, cap, etc later in the week, but it looks like I'm at least going...

    P0300 Issues 1997 K1500

    Well, I guess I spoke too soon. The P0300 is back, along with a P0161 Bank 2 Sensor 2. The misfires are worse on bank 1, and both downstream sensors are bouncing around too much, but only bank 2 threw a code. I'm about at my wit's end with this truck.

    P0300 Issues 1997 K1500

    So, an update of sorts. I pulled the cap and rotor, which was pretty charred around the button. I ordered a no-name cap and rotor with brass terminals. (I know, I know, but the "old" ones were Delco and didn't even last a year.) I slapped them on and the misfires were reduced by a lot. They...

    P0300 Issues 1997 K1500

    After retesting cylinders 2, 6, and 8, here's what I got: 2.) 130 6.) 115 8.) 120 I put everything back together and fired it up, and I'm still getting misfires, actually more than before. Mostly on cylinders 5, 6 and 7, and within the first 6-8 minutes after startup. The engine sounded like...

    P0300 Issues 1997 K1500

    So today I pulled all the plugs. Except for #1, they all had some burning near the electrode. I remember when I put them in, I forgot to put antiseize on #2 so the threads look clean, and I know that's an age old debate anyway. Number 4 seemed to break loose a little too easily, I probably...

    P0300 Issues 1997 K1500

    Fuel pressure is 57 PSI at key on, jumped to 61 at key off, and dropped to 51 PSI after 10 minutes. Looks like it should be a little higher. I'll have to grind off some of the Chassis Saver on the frame where the pump ground is, maybe that might help, or maybe I'm just stupid. I got an...

    P0300 Issues 1997 K1500

    97 K1500 5.7L MT 147,000 miles Got a p0300 a few days ago going uphill, no other codes. Nothing really noticeable with drivability. Recent history: Replaced old lower manifold intake gasket with metal-backed one in 2020. Changed plugs, wires, cap and rotor in 2021. (AC Delco) New fuel pump...

    97 5.7L: Engine stalled at light, ticking sound after restart

    I was stopped at a stoplight this morning, when it turned green, the engine started to die. I lost all power, but I was able to turn onto a side street and pull over. For about 10 minutes, there was no crank and no start, interior lights still worked. Eventually I was able to start the truck and...

    How to stop LED Fast Flash info

    This isn't really in response to anything, just passing along some information specifically about rear LED turn signals blinking only once. Last weekend I replaced the front turn signals and after trying to wire in resistors with all of the frustration and none of the success, I went to Advance...

    Weak driver's side lock actuator - 97 K1500 5.7

    Turns out the connector was bad. Because I don't have a lot of patience, I ended up transplanting the passenger side connector over to the driver's side, and getting a new one for the passenger side. I soldered the new one backwards, so one door locked while the other unlocked. I swapped the...

    Weak driver's side lock actuator - 97 K1500 5.7

    I don't know, I just can't seem to figure it out. Sometimes it works, sometimes it doesn't. I did get a new latch and squirted it with some Slick 50 lube, but I might put the original back in because the new one has a lot of side to side play at the actual latch hook. But that's a different...
