Yesterday I finally found it. This subreddit is for the Chevrolet S10 truck and all related vehicles, not the Samsung Galaxy S10 and its relatives. And had 'taped it into position'. Just be prepared to curse your truck a bunch. Engine Performance problem 1993 Chevy S-10 6 cyl Four Wheel Drive 198K miles My 'check engine light' is on. I'm not a professional mechanic, but have been able with help on the complicated stuff, like this electrical nightmare I'm currently in the midst of fix everything that comes up.
Suggestions are greatly appreciated as well as the time you've already spent assisting me. And what cam would anyone recommend for a roughish idle, good sound and good power, really appreciate your help. I have just ran the pump to empty the tank, smacking it with a hammer to restart the pump after it seizes, when I've changed the failing pumps in similar trucks before. If you have constant spark knock that is not good either. Then you need to strip the harness in the engine compartment to replace the other end as well. And left side little toward rear of head. I would test them out before trying to replace them.
How many miles on the O2 sensors? Now let it set for an hour or so, that lets the cleaner work at softening the carbon and crud up. Be very careful as the wire clips are brittle and will easily break. And when scanner is hooked up read out the data in scanner. I suppose it's possible that the plenum gasket is leaking vacuum, and that could affect more than one, if not all cylinders. Thanks again for your help and any advice. Post Reply above is the diagram for the 2003 4. I'm doing an engine swap for my son and got a junkyard motor.
I assume your truck still has the grommet inthe firewall and still has a spot inside for the ecm. Good luck, I hope this helped. I know it has fuel pressure, and I can hear the pump cycle for a second or so before I try to start it each time. The injector might clear out by itself, if it will pass gasoline through it. Or next thing to check? Don't know if anyone else has needed this answer or not, but this was my question orginally. I do that every other year to keep the engine cleaned out.
Can someone give me an idea of where the Knock Sensor is located on my 95 Blazer 4x4 V6 W in the Vin? Previously I had checked spark when it wouldn't start and it always had that too. I have also read that there may be 2 for my truck? After an hour or so start it up and drive it around. Can someone give me an idea of where the Knock Sensor is located on my 95 Blazer 4x4 V6 W in the Vin? Post Reply do you picked up a 2004 motor. The knock sensors in 4. The knock sensor is located under the manifold on the 3. Basically what you do is get the engine running, let it warm up. And also does the new ecm have the same wiring setup when hooking up to the ecm? It ended up being the electrical connector on the fuel injector.
What a waste of time. They have a few miles on them. I guess the guy's boss accidentally topped off the gas tank with diesel a few weeks ago. The service engine light comes on every now and then but goes off. Apparently someone broke the knock sensor 'connector-end' off for me and kindly 'taped' it back into place. Got a bad one or just bad wiring? Just something to think about.
My guess is you are looking for the schematic for the engine electrical which would, of course, include the heat sensor. The knock sensor you cant, the esc on your truck is built in to the ecm, the donor one will be an external esc module. I guess the 'check engine light' will 'go out' after correcting the knock sensor issue? Today I started it after replacing the coolant switch, and it started fine, ran fine for a couple min, then started surging and dropping, like it would if you had the master cylinder vacuum hose unplugged from the intake. I am wondering what the 'next step would be? I'll update when she's running, hopefully anyway. I'm in the middle of finding a solution but it may be the wiring harness as well.
Well, the new coolant temp switch didn't make any difference, in fact, it didn't even warm up enough I don't think where it could've. All fuel-injected Chevrolet trucks with gas engines as opposed to diesel engines use a knock sensor. It is made of a composite plastic so use care and do not over tighten. I'm even running premium fuel to try to alleviate the knock but it's really not making a difference plus I've never had to run higher grade fuel before to get good performance from this engine. I just dont want to be stuck without a vehicle.
It idled perfectly for 10 or fifteen minutes, so I backed it down and into a parking space, barely touching the throttle, and everything went fine, until. Get the code and go threw the repair flow chart for the code. Late 1999 to date V-8 engines have 2 knock sensors and they a … re both underneith the intake manifold. I'm sure if I wait fifteen min it'll start right back up. The only difference I have found so far is the new engines knock sensor is a two wire and the old engine is one wire. It may take some extra time, but using one of these combinations will avoid all kinds of problems in the field.
