Dodge 7,248 Posted August 12, 2014 Share Posted August 12, 2014 (edited) Thought maybe this would be a good place to start an auto repair Topic. There are forums all over the web about how to work on cars. From changing the oil, to replacing the engine. Now we have an XDBX Automotive Repair Topic. So here is a Topic for posting questions, tid bits, or common fixes for automotive problems. Personally I specialize in Chrysler, and BMW.

Dodge 7,248 Posted August 12, 2014 Author Share Posted August 12, 2014 Hey Dodge, how are you on mower repair? Brigg & Stratton 18hp boxer Twin? Im all out on small engine. Somebody else might have an idea though. Post your problem. Quote Link to comment Share on other sites More sharing options...
Beez 5,091 Posted August 12, 2014 Share Posted August 12, 2014 Well, I need to dig in further before I can ask the right questions. I was just gauging your expertise. Quote Link to comment Share on other sites More sharing options...

From changing the oil, to replacing the engine. Now we have an XDBX Automotive Repair Topic. So here is a Topic for posting questions, tid bits, or common fixes for automotive problems. Personally I specialize in Chrysler, and BMW. Haha, free car advice What do you know about the fuel sender of an infiniti G35? I know its fairly close to the BMW setup (2 senders, 1 in each side of the tank). I have already pulled both out (independently) and found the drivers side (one w/o fuel pump) to have an awkward shaped rod holding the float. Given the bends in the rod, it couldn't provide any feedback above a half tank. I looked briefly at a new unit and noted its float setup. From there I bent the rod, eyeballing an approximate full tank reading/setup. Before modifying, the gauge never read 100% full, maybe only 75% and would rapidly drop to E when empty (within 30 miles perhaps). After the modification, it displays full for ~90% of the tank, quickly drops to 1/2 a tank then to E (and can go that same 30 miles) Do you know what the ohm output of the potentiometer "should" read for each sending unit? That info sure would assist in troubleshooting Quote Link to comment Share on other sites More sharing options...
Dodge 7,248 Posted September 3, 2014 Author Share Posted September 3, 2014 (edited) Do you know what the ohm output of the potentiometer "should" read for each sending unit? That info sure would assist in troubleshooting Ohms will show the resistance. But the fuel level should be measured off of Volts. I understand that you can calculate one using the other. My understanding is that the system should rely on a 5 Volt Feed. So, you can infer the fuel level by monitoring the voltage being sent from sender. 5V ~ Full and .5V or so ~ Empty. My guess is you have a faulty sending unit. Probably a dead spot or 2 on the potentiometer. Now you have figure out which one it is. Left or Right sender. Fuel level is usually determined by an algorithm in the PCM based on voltage output from both units in the saddle tank. That doesnt really make manual diagnosis easy. The only way I know to diagnose that issue is to trick the senders into believing that one side is fuller than the other, and make the transfer pump engage. Hopefully this helps a little.

I understand the principle and the application, but if I had one in my hand, it might as well be a paper weight. Quote Link to comment Share on other sites More sharing options...

Thanks Dodge. I'll see what I can figure out Good info BTW! 1 Quote Link to comment Share on other sites More sharing options...

I know a little, rebuilt several Quadrajunks back in the day, and a few Holley's 1 Quote The funniest thing about this particular signature is that by the time you realise it doesn't say anything it's to late to stop reading it.

shortround 1,160 Posted September 16, 2014 Share Posted September 16, 2014 I have a mk5 VW Golf GTI, I was driving earlier and overtook someone and I looked in my rear view and saw a puff of smoke. I didn't get a real good look at the colour but I think it was grey. Any ideas on how fucked she is and do I need to burn the fucker out?

Smurf 947 Posted July 3, 2022 Share Posted July 3, 2022 (edited) broke my ignition coil in 2 after changing 8 spark plug, right where the coil starts, then I lost the nut cap. The question is, is it safe to drive if I put the 2 parts together and screw it down with a screw from another ignition coil just to keep them all firing?

If it fires, it'll work for a little while. But I'd get a coil on order. 1 Quote Link to comment Share on other sites More sharing options...
