    EastMT was correct about the fan signal. I hooked up a test light to the battery positive terminal and the fan wire. Sure enough the light came on at about 204 degrees when the temperature sensor sent the ground signal. So then I rewired the fan relay to have the ground connected to that wire...

    The fuel pump I'm using is a Walbro GSL392, 255LPH. Worked fine on my Ecotec, but yeah, my 80 psi reading is a lot higher than your 40. Is there a recommended/ideal fuel pump for the Honda V6?

    OK, I will look into that. Thank you. The fan definitely should have turned on by 208 degrees. The wire coming from the harness was red, so was assuming it was either wanting or sending positive voltage. Wait... that was the color of the wire spliced in by previous owner. On closer look it...

    Thank you for looking into that. I have replaced the original IAC with a new one, but I will do a good cleaning of the throttle body and IAC passage and see what happens. Fuel pressure regulator costs about $140, so not replacing that unless needed. I found no gas in the vacuum line that's...

    Thank you for the suggestions. I'm curious why the drive by wire throttle body worked better. I have an inline fuel pressure gauge. It's reading 80 psi. I'm using the same fuel pump that was in my buggy that worked fine for the 2.2 Ecotec I removed, but that is something that is different in...

    More info: I can start it, put my gloved hand over the throttle body and it immediately dies, so no vacuum leak.

    Well I am not having much luck with this surging idle issue. I replaced the IAC, no change. I replaced the MAP sensor and connector just because the the wires were hot glued into it (previous owner), no change. I pulled the plenum and intake off again to see if anything looked suspicious. I...

    Yep, I did that. I couldn't pick up any changes in the idle when I sprayed all around there. Maybe I just missed the leak location. I went ahead pulled the intake off to have a look and the gaskets seem to show some fluid on them from when I was spraying, but it could be my imagination. The...

    Well that start up joy was short lived. When I fired it the other day I did not let it run but for a few seconds and then shut it off. Today I went to start it and let it warm up. The idle is revving/jumping between 1000 and 200 rpm. It could be a couple of things: Vacuum leak? I pulled...

    Yep. I noticed that on some of the connectors you really need to tug on them to make sure the clip is engaged, especially the fuel injector wires.

    I found a wire I had taken out of the system because it was part of a funky relay routing the previous owner had. Turns out I needed that wire hooked up, ha ha. Got it to fire! Now to button up everything and take it out for a shake down run. The MAP sensor wires look like they are...

    Well my J35A4 engine swap has hit a bit of a dead end. I transferred the (running) engine, ECU, and harness from another buggy into mine and I messed something up along the way somehow. Everything is hooked up as it was as far as I can tell, but it won't fire. Starter cranks because I have it...

    Proportioning valve

    I had a sand car that had one. It was running front and rear disc brakes off of one master cylinder, so the proportioning valve was used (near the master ) on the line to the front brakes. A better set up would be to have two master cylinders for redundancy. If you lose a brake line or caliper...

    Alternator amperage

    I talked to the guy at the Sand Sports Super Show that has the alternator shop: AutoTech Engineering. He was very knowledgeable and and seemed like he could build an alternator to fit pretty much any engine and any amperage level you want. He was very helpful. I would think he would be a good...

    I had just walked away from the demo when we heard the crowd, so I only got back in time to see him up on the k-rail. There must be videos. Seems like a lot of people had their cameras out. He got out and up on top of the car and laughed it off. Stuff happens when you're putting on a show for...

    It's Saturday Sept 7th 2024.. What's everyone doing this weekend?

    Made a footrest today for a buggy I'm putting together. I should be working on getting it running, but this was more fun.
