Gary Lewis Posted August 19, 2021 Author Share Posted August 19, 2021 Me too. And I'm actually on a bit of a roll with that. The trailer wiring was last night. Tonight I looked at why my walk-behind mower's transmission was locked up. Turned out to be a piece of a stick wedged between the pulley and the guard! Took about an hour to get it apart to find and remove the stick and then put it back together. But I was expecting to find stuff shredded inside the transmission. I should probably try some other projects before my luck runs out! I'm also glad that you were able to get your truck back on the road! Bob - That is great luck! Both on the wiring as well as the mower's transmission. Hope the luck continues. Link to comment Share on other sites More sharing options...

Well, I'm still having absolutely no luck getting my truck to run. Replaced the TFI and distributor and now I have no spark at all. Anyone have driveshafts for a C6 4x4 truck? I'm /this/ close to doing a complete drivetrain swap next weekend. Link to comment Share on other sites More sharing options...

Even so, are you getting good voltage through your ignition switch? Link to comment Share on other sites More sharing options...

ArdWrknTrk Posted August 21, 2021 Share Posted August 21, 2021 Yes, it turns over great. 12v at the coil. Fuel, compression and spark... One of those three has to be missing. 🤷♂️ Link to comment Share on other sites More sharing options...
Angelo Voltura Posted August 21, 2021 Share Posted August 21, 2021 Fuel, compression and spark... One of those three has to be missing. 🤷♂️ Had all 3 and good timing and it still wouldn't pop off. Now it has lost spark entirely. I'm starting to think there is a broken wire in the engine harness somewhere. I'm at my wits end and about to send it to the scrap yard and cut my losses. This is the project I was trying to avoid. Link to comment Share on other sites More sharing options...

This is the project I was trying to avoid. I hear you. But compression doesn't rely on a harness. If you have a noid light you can see the injector pulses. Now you know you don't get spark. Unplug the SPOUT. If you get spark then, it's the ECU. If you still don't get spark it is the coil or PIP. There's not much else... Link to comment Share on other sites More sharing options...

Had the ECU apart and verified the circuit board was OK. Just checked 3 different coils and all of them had 0 resistance between terminals, so I might be onto something now. I'm just frustrated.

I got the time to swap in a new NAPA fuel filter this afternoon. I'm busy getting my dock locker to higher ground. Link to comment Share on other sites More sharing options...

That reminds me to put that on my list. Swapped coils, no dice. I'm ohming wires to the TFI module right now and found one that has 2.2 ohms resistance, so looks like I'm going to be opening the engine harness. Also, something keeps beeping at me over on the drivers side the more I keep wiggling stuff around. Link to comment Share on other sites More sharing options...
