    Stumped, no spark=no start

    Woot Woot ! She runs !!!!!!!!!!!!!!!!! and she is running pretty good too, idling really low (400 rpms) but revs up nice and purrs. I think I took the hard way to a crash course in 3FE. I changed out the fusible links, nada, soaked the CSI in carb cleaner while replacing the sock. Put it all...

    Stumped, no spark=no start

    Tested fuel pressure at the CSI with the B+-FP jumped, key to start, got 12 psi. Too low, so I plan to pull the pump and replace the fuel sock and check it again. I also checked the fuel cap and it was under vacuum after days of not being opened, whatever that means. Also replaced the fusible...

    Stumped, no spark=no start

    10-4, I will resist the urge to mess with the screw. I picked up a fuel pressure kit this morning at Autozone and will look for a spot to hook that up. I'm still trying to wrap my brain around the circuit that fuel takes to start and run the engine. Is there a split where fuel runs to CSI first...

    Stumped, no spark=no start

    09/17 Update - I tried starter fluid and she runs ! Sounds like a cinder block rattling in there but she is going full revolution. I ordered a fusible link set and fuel sock and they should be in tomorrow morning. I will install those and give it a try. IF that doesn't do it, I will check...

    Stumped, no spark=no start

    ZA80 - I'm not sure what that is but I will look for it. Tricky - I will do the links as a maintenance/rule it out item. I tried starting with the B+ to FP, no luck there. J- I pulled #1 and smelled a hint of fuel on it but it did not look or smell fowled. I may pull some more and check them...

    Stumped, no spark=no start

    9/16 Update - Rechecked Jon's list items and found; Coil reading for original Coil, Primary reading of 0.9-1.0 and secondary Reading 12.8. The just purchased after market coil read 2.3 and 13.37. Have the original on now as it is closer to spec. * Pickup coil values are G to G- = 257 and NE...

    Anyone know where to connect a remote start switch on this rig ? I will be doing the troubleshooting by myself today.

    I will go with an off the shelf for now. Autozone is close. Next tune up I will order OEM. Once again I am getting confident for my next session of TLC anger management therapy. I will keep you guys posted, thanks again Kirk

    Stumped, no spark=no start

    Mine is that color, maybe even darker. It is not imploded, more wedged shape. I will go ahead and change it, might as well while I'm in there. Are they easy to get ? I need to get rolling soon.

    Stumped, no spark=no start

    Frank, thanks for the ideas. I am trying to put together a check list of sorts to work off of and write results. Will definitely check all connections I can see or pull. Summit - Before I pulled the pump, I thought it had never been serviced due to all of the crud on top of the tank. After I...

    Stumped, no spark=no start

    No Tricky, I just checked fuel pressure at the CSI after trying to crank it for a bit. I knew I would need to fill the filter and lines and possibly crack off an air lock. It shot fuel out, no air. I have 12+ at the Diagnostic points and confirmed visually the pump works. I will try what you are...

    Stumped, no spark=no start

    No offense taken. Obviously this troubleshooting adventure has me troubled and I feel like shooting the truck. I put direct from battery power to the connector inside the cabin under the floorplate to the pump. I could not hear it pumping and assumed it was inop. Couple days later I pulled it...

    Stumped, no spark=no start

    Update, tried shorting FP circuit at diagnostic port. Also tried moving the dizzy to different positions. No luck. Same deal, get an initial running spark and it dies off within two seconds. Looking thru the archives, I started to think it was AFM (which is why I hot wired the FP). Next I will...

    Stumped, no spark=no start

    I want to thank everyone who has chimed in to lend a hand. :) My parts came in, just installed them and still no start. I am definitely getting a spark now as the engine is stumbling, she is really close. I wonder if I jumped time on my last trip out as it was backfiring a bit. I have not...

    Which one should I sell?

    I had a 6.5 '95 suburban and miss it. I am looking for another. I need the additional seating or I would recommend you sell the Tahoe, ...cheap,........ to me :)

    No Spark in my 3FE 1990 80 Series. At wits end need help please

    I have been following this and glad to hear you have spark and found the problem. Did you check continuity at the fuse panel and each accessory to find the break? I have a similar problem and would like to know how you found the open circuit. That is something free I can check while I wait for...

    Stumped, no spark=no start

    Will do Jon, I think I have messed with enough for today. I did pretty much confirm the pump is inop, ran wire straight from battery to the terminals at the connector, nada. I plan to pull it this weekend and confirm. At least it will give me an opportunity to clean things up and replace the...
