    Quite possibly! We have ratzillas here in Hawaii that’s for sure! I’m not sure if I fixed the problem for sure but at least he starter is working properly now. Now onto starts but stalls within 5-30 seconds! Lol my problem child of a truck

    94 Silverado Starter Keeps Turning After Engine Starts?? Please help!

    I went through the wiring diagram in my Haynes manual for the 88-95 starting and charging system. Noticed in the diagram that there’s no start relays to work with and that the wire is supposed to be purple. Went under to check and found that the starter switch ignition wire was red. Hm...

    Unless it’s touching on the ‘inside’, no it doesn’t appear to be touching. I did check that.

    94 Silverado Starter Keeps Turning After Engine Starts?? Please help!

    Found out there’s 2 different starters. One is a Direct Drive, other is a Gear Reduction. First one is $34, other is $99. I did some checking on the starter switch wire to the S terminal on the starter solenoid. At key on, not cranking, the wire is getting ~3.08V. At key on, cranking it’s...

    Truck Stalls But Fuel Injectors Keep Spraying?? Video Included

    I went to remove the Knock Sensor to try to OHM it and the center piece of the sensor was spinning inside itself. So I removed it for now and will be replacing it with a higher quality part. I know I need the 3900 OHM sensor and not the 99000 OHM unit. Trying to read up on how to OHM the sensor...

    94 Silverado Starter Keeps Turning After Engine Starts?? Please help!

    I’m going to remove he starter and get it tested. I replace the ignition switch with a known good switch with no change, so it’s not that. Yes you can buy just the solenoid, but a new starter is just $8 more. This starter is new(rebuilt) at $37.99 from Oreilys.

    I will order the Knock Sensor connector later today. I’m going to also probe the wire after the connector and see there’s a difference in voltage.

    94 Silverado Starter Keeps Turning After Engine Starts?? Please help!

    I went to replace my Knock Sensor, turned it with a socket but the inside part just spun. So I removed the starter to gain access to the Knock Sensor with my RoboGrip pliers. Put the starter back in and now it won’t shut off even after the truck starts? It sounds awful while the engine is...

    Truck Stalls But Fuel Injectors Keep Spraying?? Video Included

    So the temp gauge not correctly has been fixed. Turns out it actually was the sensor. Went though 2 before I had a good. Standard Motor Products regular line, not the T Series. That’s what worked for me. Truck is still stalling and fuel injectors keep firing after truck stalls out.

    94 K1500 5.7 - Can’t Figure Out Code 43!

    O2 sensor not it. My Sgt. is a mechanic and gave this to me while we were discussing the issue one night. Figure I’d pass this along for anyone else who may find this useful.

    94 K1500 5.7 - Can’t Figure Out Code 43!

    I have no idea? I looked underneath and see it’s got 3 wires on it. Also found this at the front of my wiring harness. What is this supposed to be? Some kind of connector that’s been jumped by a piece of wire. Update: O2 sensor appears to be factory. Whatever was OEM.

    94 K1500 5.7 - Can’t Figure Out Code 43!

    I can’t for the life of me figure out this Code 43. Comes on a few seconds after start up. I’m getting 4.94V at the connector with the KS unplugged. What else is there to check? Thanks in advance for any help. The parts below are new. PCM Computer Distributor Cap and Rotor Spark Plugs and...

    I see. This circuit does not go the PCM, it goes directly to the gauge cluster. I’m wondering why there is a Voltage difference, if that’s a symptom of a problem somewhere else. Also, is my Knock Sensor supposed to be getting 5V as you stated? I’m getting 4.94V

    I will be looking into that tomorrow, thanks. Also getting ready for the SuperBowl at a friends house, but had enough time to start proving my ECT sensor at the cylinder head and I found this.. I’m getting 12.49V at the battery positive terminal, BUT.. only getting 12.15V at the electrical...

    Found this in my Haynes manual. I don’t see any fuses or fusible links in Circuit 13 DK BLU between the Knock Sensor and the ECM. I will be checking this wire in the next few days.

    Truck Stalls But Fuel Injectors Keep Spraying?? Video Included

    So being that I just replaced my PCM, the other possibility is the PROM/MEMCAL that clips into it, correct? I’ll try to be on the lookout for one locally and online. Is there any way to check the ESC circuit? I bought a Haynes manual and will be trying to read through it today. I don’t exactly...

    Truck Stalls But Fuel Injectors Keep Spraying?? Video Included

    It was. Might be going AC Delco/Delphi from now on lol I could try and check that. I do have a multimeter. Yes, new ECM went in yesterday. No change in truck behavior. Just can’t get rid of this Code 43! Online it looks like a black and red flat chip. I went looking in my engine bay and...

    Code 43

    I’m having this on start up. Did you ever figure it out?

    Truck Stalls But Fuel Injectors Keep Spraying?? Video Included

    Replaced ECM with Part# 16196395. Still Code 43. Tried to drive it and truck stalls when I press the gas pedal. It’ll start right up in Neutral, but it will stall if I step on it again. I’m not flooring the pedal, maybe only 30-40% throttle. Seems better with lighter pressure than heavy. I’m not...

    Fixed fuel pump issue! Here’s the problem. Not sure why, it’s new. But I guess something broke internally. I unplugged this Oil Pressure Switch and the pump went off. Plugged in a new one from OReilys and no pump noise. Replaced the new one with the new new one and it’s working properly...
