billyboyxoxox Posted April 30, 2016 Share Posted April 30, 2016 I know this is getting old. I've gone over everything in Cruiser54's tips and upgraded the grounding with Napa cables from the block to the firewall, the negative battery terminal to the radiator support, the fuel pump ground to frame, removed the C101 and cleaned and even soldered the connections by the dipstick tube. The CPS is putting out .8 vac and is a new Napa part. The coil and ICU are only month old. The ECU is only about 10 days old. I even replaced the ignition switch on the steering column with a new Napa one. The truck last started when I put the old distributor in with the harness unplugged. I forgot to do that and it started right up. I plugged it back up and it warmed up for 5-7 minutes before it died without fire again. I've tried unplugging the distributor harness again but nothing yet. I'm turning the key on and jumping the starter relay and the coil only fires when I let off. I will tell you honestly that I'm touching the coil with my finger and taking it and of course it shocks the hell out of me but I promise I'm tough enough to do that no matter how crazy it sounds. There is of course power to the coil with the ignition on. Has anybody ever experienced a problem like this? What am I missing? I'm so sorry to bother you with this but I need and miss my truck! I won't be allowed to borrow the one I've had this past week much longer. Link to comment Share on other sites More sharing options...

billyboyxoxox Posted May 1, 2016 Author Share Posted May 1, 2016 The C101 has been eliminated. Maybe I'll go over the joints and make sure something hasn't failed. It's really an odd problem. Link to comment Share on other sites More sharing options...

billyboyxoxox Posted May 1, 2016 Author Share Posted May 1, 2016 Yes, the wires are all soldered very well. Like the one fellow who commented on your tip 26 for getting rid of that connector, there are four wires that had no mates. Three on one side and one on the other. They are taped up. There are only a couple of pair where the colors don't match from side to side but the gauges are correct and I was extremely careful and used a continuity tester on each pair before I made any cuts. --It will give me a fire when I let off the starter but nothing while it's turning over. That's what surprises me and it did start and run for about 7 minutes last week before it died with no fire again. This is an unusual one isn't it? I have to do this by myself so you are the only other brain right now. I'm taking a break while the rain comes down and probably will give up for the night. My poor starter is taking a lot of extra work! It's not that old and holding up better than my battery which is 4 years old and will get another charge tonight. Thank you for all of your suggestions Cruiser! We'll get it sooner or later. I got a can of electrical parts cleaner and sprayed all of the connectors under the hood out and even took the ECU off and sprayed those connectors out real good too. Just for the heck of it I took a wire wheel to the ECU mounting points to make sure it was grounding well. It has ground continuity every place I've tested and as far as my tester wires will reach.

cruiser54 Posted May 2, 2016 Share Posted May 2, 2016 That could be a faulty ignition switch..... Link to comment Share on other sites More sharing options...
HOrnbrod Posted May 2, 2016 Share Posted May 2, 2016 Jiggle the connections then. Wiggle the C101 while cranking. Jiggle and Wiggle! :banana: Hope you find it OP........ Link to comment Share on other sites More sharing options...
billyboyxoxox Posted May 2, 2016 Author Share Posted May 2, 2016 The ignition switch is a new Napa part. It seems to be adjusted correctly. It will turn the motor over like it should and of course all the dash lights are doing what they normally do. I've tried jiggling it when the ignition is on and then jumping the starter at the relay but it's always the same. I'm doing this by myself for now. The coil will fire only when I take my screwdriver jumper off and not every time. I remember when it would run weeks ago I would get a constant shock from the coil when jumping the starter relay, plug the coil wire back up and it would start and run and get me to my next stop. If and when I find my problem, I promise I'll post what I learned for others. I promise I'm tired of this! Thank you for your help! Link to comment Share on other sites More sharing options...
