#fuelinjection โ€” Public Fediverse posts

Live and recent posts from across the Fediverse tagged #fuelinjection, aggregated by home.social.

  1. Because of AI slop and confusion caused by (often well-meaning) Americans on international online spaces, I was unsure if the engine on my #GolfGTI had just direct or multi point #fuelinjection

    Managed to snag an official VW workshop manual and checked with my own eyes, was pleased to see the CHHA engine in my car does indeed have the extra fuel rail and injectors in the intake manifold (this is good, as #petrol sprays over the back of the intake valves and keeps then cleaner, without it they are prone to coke up and require walnut blasting)

    I do not know why Americans only get engines with direct injection (into the combustion chamber), whether this is simply cost cutting by #Volkswagen of #America or some other reason..

  2. What makes this even more mind blowing is that Formula 1 engines rev past 15,000 rpm on the regular (not sure how far, I seem to recall something like 18,000). Just watching the fuel injectors, that means the metal pistons are going up and down equally fast! Mind blown.

  3. Well... there's still no ground at the #19 wire, just 11.4v positive. Why would a working ECU that's supposed to put out 12v ground on the fuel pump relay #85 be putting out positive. It should never put out positive. Is there a short in one of the other 30 or so wires!?

    I fucking hate #electronics

  4. I don't know what to do next...

    I could try another ebay #ECU, pour another $100 down the drain, and pray that it's not fried too.

    I could try to replace the original ECU and wiring with a modern #MegaSquirt ECU.

    I could tear all the fucking #fuelinjection shit out, find some #carburetors, linkage, manifolds, and low pressure fuel pump.

    I could buy a $20k electric conversion kit.

    I could set it on fire and roll it into the Columbia river.

  5. I am so fucking sick of this. I've had this car for over a year stinking up my garage and I haven't even gotten the fuel pump to come on.

    I bought a spare ECU, I sourced a replacement transistor, I soldered it on an ancient PCB, I've traced wires all the way from one end of the car to the next.

    Fuel Injection was a mistake. I see why everyone converts these fuckers to carbs.

  6. I finally got the ECU back together, so now I have to try and remember how to test it to see if the new transistor fixed it.

    I should be getting 12v Ground on the #19 wire for a few seconds after turning the key.

    Fingers crossed!!

  7. See here's my perfectionism getting the better of me again; I want the ECU's fuel pump relay circuit to work, but I could easily just ground the #19 wire and it would run the pump as long as the key is on. In fact, the previous owner just bypassed the relay entirely with a wire directly to the fuel pump.

  8. Well, fuck! (i.r.t. mastodon.social/@schizanon/112)

    Battery is at 12v, and I'm supposed to get ground from the #19 wire from the ECU but I'm getting 11.2v which I see at the relay as well.

    Either this ECU has the same problem, or the issue is somewhere else.

    I don't know what to check next; maybe check for a short in the ECU harness?

  9. I'm getting 8v positive at this wire with the key on and the ECU connected, which is probably a bad sign. ๐Ÿ˜Ÿ

    The shop manual says the ECU should be sending ground.

    Either the ECU is fried or there's a short somewhere in the wiring harness.

  10. I noticed the wiring diagram mentions a "single wire connector" somewhere along the wire that runs from ECU 19 to the fuel pump relay terminal 85. I followed the wiring loom into the engine bay and found this grubby looking connector. I tested from the ECU connector 19 to it, and there was continuity. Now I need to test for continuity across it. I've got a feeling this could be the problem.

  11. More bad news: according to the manual, the ECU sends ground to the pump relay to trigger it, and I'm not getting ground on that wire. So either the ECU is bad or the wire that runs to it is disconnected somewhere. I'm hoping it's the later.

  12. After months of putting off installing the new fuel pump relay on my #vw #type3 #squareback, I finally got around to it.

    Bad news: this was not the fuel pump relay. ๐Ÿ˜ฉ mas.to/@schizanon/110605332390

    Good news: the actual relay is still connected to the wires that run to the ECU and Voltage supply, so I don't have to search for those anymore!

  13. After a couple months of sitting in the rain with the passenger door unable to close I finally got the #Squareback wedged into the garage!

    Now I can take the door off and start prepping it to weld a new hinge on.

    It'll also be a lot easier to work on the #fuelInjection without having to deal with the weather!

    I just need to get rid of some stuff to make some more room.

  14. Any #electronic experts have recommendations for a #multimeter?

    I need to figure out which of a loom of wires coming out of my car's ECU is supposed to be running to the fuel pump relay which a previous owner deleted.

    I've heard that "clamp" style meters can measure wires without probing them. Will that work if the wire I'm looking for has been disconnected?

    Any other features I should look for?

  15. I've got to get out there and finish installing the fuel pump relay on my #VW #type3 ๐Ÿ˜ฉ

    I just have no idea what to make of this mess of old fucked up wiring, and a mental block about #electrical in general.

    I think this is the "Voltage Supply Relay" so one of the wires that runs off of it will go up front to the fuel pump relay. Then I just have to figure out which wire runs to the ECU.

    I think I need an induction loop meter...

  16. I got my new fuel pump relay for my #vw #squareback, now I just have to find the wires that some monkey cut off to bypass the old one. The diagram shows wires running to the pump, ECU, voltage regulator, and auxiliary air valve. I *think* I know where all those are, and I have a test light so I can tell if they have voltage.

  17. What's this? The #fuelpump relay? Some fucking monkey decided to wire the fuel pump directly to the ignition switch. So as long as the key is turned it'll squirt #gasoline. This #car is a bomb! How did anyone survive the 1970s? #volkswagen #vw #aircooledvw #type3 #fuelInjection
