I meant coil for both.

 

thinking out loud - w/o an expensive scan tool - can you test to determine if the ASD is being tripped. does the pcm put a signal on, or take a signal off the ASD relay or some other measurable point?

 

Ill have to check more tomorrow. Raining hard right now. Got my other truck that's down at the moment in the middle of my carport and the debris of my kitchen reno in my garage...

Any suggestions to get at the rotor cap easily? That thing is back there!

 

put a piece of plywood across both fenders and lay on it.
raining cats and dogs over here too.

 

Yeah, I'm not having challenges with leaning into the bay, just getting my hands under the cowl and then back behind the engine... may have to take apart more than I want to... I need to find a flow chart of how the spark system works... I think I know off the top of my head... but I'd rather be able to trace it back or forwards to save time. Borrowing my buddy's '85 Jeep Cherokee 5spd... but it's still raining here, his wipers don't work, went to pull the lights button, came right off... yeah...

 

Oh yeah, forgot to mention, for several weeks now, my radio has been powering on/off when driving... if I hit a bump, like a pot hole or speed bump, the radio would typically power off... then come back on after another bump possibly... so I'm thinking loose ground somewhere, because I know the hot is good... could a common ground through the truck cause a no spark scenario?

 

check the ground at the power steering pump bracket. thats a quick way to lose spark. been there done that a couple times.

 

Fixed my issue.

Probed the ignition plug, not the disty cap wire, but the two wire plug on the bottom. Grounded it out on the battery. Put the voltmeter against my window to see it while cranking the truck. Wasn't getting my 12v while cranking so it lead me to the engine computer... Checked the 30a fuse in the relay box, looked fine initially, but I popped off the clear plastic tab and the fuse link was barley blown...but enough not to send my switching signal to the ignition coil... I bent the link back together for test purposes, cranked the first try. Voltmeter read the 12v I needed. No idea why it blew... Aside the short in the radio I have. Ill have to trace it down this weekend. Bought an extra 50a fuse in case it blows while driving again. At least that way I can limp it to safety then figure it out. But for now, she's back on the road!

 

good work.

 

So I spoke too soon... I've now put 5 fuses in my engine computer slot under the hood. I bought an extra just in case... And guess what... Fuse blew while pulling my trailer. Picked up a 79 hatchback civic to haul back to my place, blew fuses twice more. I pulled the fuses for anything I "modified" while on the road...so that would include ge radio and cig. lighter fuses. I can't think of anything in particular that is happening to cause the fuse to blow... I had the called for 30a in it, blew... Put a 40a... Blew...50a... Blew 3? After tha one to make it home I pulled out a 60a... My buddy put that one in and he said the link inside the fuse almost instantly browned, but didn't blow. I haven't had time to go back and check it...I'm looking for suggestions on where to look for the issue... I would assume probe backwards as the surge has to happen before the fuse...right? Or could I come from either direction as a surge? Does it have to be a surge, could it be a grounding issue? I'm at a loss.

Thanks.
