Cody's 2011 GMC Sierra 4.3L

Taking it down to put on the Mazda. Fingers crossed it’ll work on that.

The gasifier sure did make a lot of water. Water every step of the way. Filter box has the most, filter bag was a little caked up but it slaked off when I jostled the bag.

After the filter the water was crystal clear so that’s a good sign. No dust sneaking past the bag.

I guess I should make a condensate tank before the filter to get the most of it out.

I would try it without killing the injectors, or try unpuging the injectors, while still leaving the injector fuze on. See if it gets spark that way. Or check around for the wireing skidmatic,Too see what else the injector fuze powers up.

You may have pulled wrong fuze?

Well the problem is it has the Spider injectors and it could burn it up if I left it running without the fuel pump on.

The number 1 killer of Spider injectors is when the fuel filter gets clogged or the pump gets weak and it makes the injectors work harder.

It could just as easily just be weak gas. Gasifier not having a big enough nozzle or something. I’d rather put it on the Mazda and leave the Sierra be for now. That way I can keep the miles low on the Sierra and just drive the clunker Mazda.

I don’t want to spend much more time on the Sierra and having to do more wiring for it. The wiring diagrams aren’t helpful and they don’t account for stuff like alternative fuels.

Also as far as if I got the right fuses, I triple checked. I’m using fuse taps that relocate them and put in a switch so I could reverse it and not mess with the original wiring.

Sorry too here you not having the best luck with the seara truck, but i know what you mean, somtimes its cheaper on time and money, if you catch a lemon truck for wood gas or charcoal. I wouldent wood gas the spider injection either, unless there was a conversion kit , too change it too port injection. You could trade the siarra truck in on a decent dakota truck, possible.

Are you sure the spark dies when injector power is unpluged, A spart tester is under 5 bucks on ebay, they plug in line with spark plug. Maybe you should check for a flare, Just before the air cleaner butterfly.

I’m still making payments on the Sierra. It’s otherwise a good truck. I guess I’ll just do some fuel economy mods like a hard bed cover and other stuff to reduce drag.

I did check a flare it was making good gas. I didn’t have a test light but I just can’t shake the feeling it’s a combination of things that I don’t have the patience for. I know the Mazda will burn woodgas no problem, I would have focused on the Mazda if it hadn’t been screwed up when someone decided to T Bone me in a stolen car.

What if you leave the injecors on, and run hybrid, so the injectors are not clicking dry. Just turn the fuel way back, just enough too say a real low idle, and power the rest with charco butterfly and less wood char throtal needed. Might be worth a try, shouldent be any intake problems of tar ,since your useing charco gasifier.

Hmm, I have spider injection in my S10a, do you think it breaks, I’ve been driving it for quite some time.

i think the only thing i thought might be problem with spider injection is the fact that they use plastic lines too each injector in the intake, so was thinking might be problem burning the intake, out when suit builds up, because on the wayne keith trucks, they intentionaly put the torch too the intake, too keep suit from lighting up on its own unexpeting. With wood gasifier though not with a charco gasifier. MAYBE the plastic components in the intake could be exchanged for all steel components, would be more fire proff if intake were to light up on its own from suit build it. When intake lights up you would see a trail of smoke roll out the tail pipe for X emout of time.

Ok, I don’t dare set the intake on fire, try to clean the gas as best I can instead, and have to clean the intake by hand if that doesn’t work.

Jan I think with your steam cleaning bubbler it should do a good job of keeping the intake clean. You could also run the engine on gasoline and spray it down with Carburetor Cleaner to the throttle body if the bubbler isn’t working fast enough.

I tested the bubble can for 2 weeks, noticed no difference in the amount of soot, it probably only affects the tar.

If you do take apart your intake be very gentle, typically that will break the spider injectors piping. I think you’ve dealt with that once before.

It works quite well when I have foam rubber on top of the clay balls, there is not so much soot now.
I’m down to 1.5" thick now, so it’s pretty easy to wash, will stay that way until I get the other filter ready, trying it on the iller now.

I forgot about Mike LaRosa’s method for cleaning his intake. He had a plastic intake in his S10 so what he would do is boil water and while the engine is running on gasoline he would slowly pour the water, just a small trickle of it at a time. It cleaned his throttle plate pretty well.

That s10 spider injection,plastic intake half, should be made too easly take off and on. Maybe a better quallity neaprene gasket, Or what am i missing, you say it breaks the plastic plumming, removing the plastic half cover, or is the plastic cover tied too the injectors ,all one peice.?

It breaks the injector assembly. Usually small cracks but it’s enough to cause a fuel leak.

Maybe some one could make a jig mould and poor an aluminum intake upper, or can you buy a aftermarket aluminum upper half intake. Thanks I still like my chevys if i could find a port injected all aluminum intake, or throtal body v8 s10 would be NEAT. I think the carbs and throtle body trucks caint hybrid, but work full wood or full gasoline.

You can buy Mercruiser intake manifolds for the 4.3 boats. It’s cast iron and the new gen is common rail MPFI. Only problem is it’s about 800 bucks now and it wouldn’t solve the potential computer issue.

Plus I’d need to get a more powerful fuel pump and add a pressure regulator inline
For @Jan it would probably be branded under Volvo Penta.
