I have a 1998 gmc and I love it ! You do have to keep it up ! On my distributor only problem I have had is in humidity buildup so I sprayed some anti static from Auto zone. Never had any problems. I’d driven from New York to New Mexico with no proplems. And did have to replace the camshaft sensor once .
I am honestly just real sick of the ignition system in this van. In 30k miles I have replaced the cap and rotor about 6 times, and replaced the entire distributor..... just... wtf.... this is a basic simple engine; it should not have ignition issues like this.
@@ADDvancedthat’s crazy it’s one of those wierd things. I just replaced the starter on my 1998 GMC Safari also AWD but what was happening was that it’s kept engaging even after I turn it off and pulled the key out of the ignition I was like wtf . I end up de connecting the battery 🔋. At the end it was the starter never had that happened to me 😮😮.
@@knightryder5292 That problem is usually a bad ignitions switch that doesn't return all the way after twisting; but I guess a sticky solenoid would cause that too!
I ran into a similar problem on a 4.3. It was burning a hole through the rotor. Did it again in a few month. I replaced a 2nd time with higher quality Standard brand rotor and replaced the plug wires and didn't have a problem again.
mi chinese distribuitor assembly from amazon developed a little play after few months what made the shaft to go up like 1/10 0f an inch and destroyed 2 rotors center metal contact, so i fixed my old distribuitor assembly and even the misfire codes went away
@ADDvanced I ended up fixing my older original part and misfire codes are gone, still going to modify my Chinese distributor assembly to have it as a spare
Okay. Here’s the deal. You have to use factory spec spark plugs. The aftermarket cap and rotor short out. Stick with factory ignition parts. Also the distributor main gears wear out and sometimes the pin sheers off holding the gear on the distributor shaft. Pull the distributor and check the gears wearing pattern. 21 year master GM drivability technician. I’ve seen a hundred of these. Fact is got a 1998 Astro sitting in my driveway. It gets allot of attention. That’s how it goes. 🤷♂️
Keep watching, the problem was ultimately solved by modifying the distributor hold down, and tweaking the distributor angle until the spark was very short. As the engine wears, the timing chain gets slack and the distributor is slightly behind where it should actually be. The spark still fires at the correct time because CPS hasn't been affected, but the distributor has lag. In one of my later videos I show you how to do it. By the time I did this video, I had already replaced the dizzie with a billet unit, brass/cap and rotor, new OEM plugs, etc etc etc. Didn't help. Modifying the hold down on the distributor was the solution, it's been 7500 miles since and no issues.
Good reply to ignition issues. However. Theirs a timing mark on the crank pulley. Mark it like old school timing adjustment. Put the timing light on #1 spark plug and check to see how far advanced or retarded timing is.
Exactly. So why adjust distributor. The timing mark at the base of the distributor marks DTC or number 1. It should line up with rotor point as well. Just saying that if you have a timing light you’ll notice it’s fixed and controlled by pcm and ignition coil on the coil itself. Also. If the cam is advanced or retarded because of slack in chain then so is the valve timing.
I've had all kinds of issues with my distributor I've gone through at least a dozen distributor caps and rotor caps I'm thinking the previous owner threw on some piece of crap aftermarket distributor the worst part about it is when it rains out I don't go anywhere it just will not start crank but no start it's not a fuel issue I've gone through two coils plus the original one that was on the van.... so let me clarify that I'm on my second coil the one that was on the van then another one and now the one that's in there now. I'm thinking about buying a new distributor don't know what kind I think I just have some piece of crap in there I thought about drilling holes in the bottom of I thought about buying a vented distributor cap but when it really comes down to what I think I just have a bum distributor. But what's really perplexing it runs smooth as silk park it overnight and if it rains it's crank no start until the sun comes out and bakes the front of the hood. Then Zippo it starts up. Which kind of makes me think do I have a relay problem realize do wear out a relay is almost like a circuit breaker it pops it resets but being mine's a 2005 with about $184,000 miles on it I wonder if the relays are just worn out and which one would I replace that was one of my thoughts start with a relay and then when I back enough money get a decent distributor soon as I can figure out which one to get I thought about an AC Delco I also thought about a summit racing one your thoughts would be greatly appreciated. I'm just tired of going out to the van after it rains and it's a crank no start it's become very unreliable in bad weather but when the sun's out she runs like a champ.
Dude, you've been told several times throughout the Facebook groups on which distributor to use as a replacement. You're just repeating yourself over and over again. Lol
@@ADDvanced my comment wasn't directed at you. I'm talking to Alan Brophy. All he does is ask the same question over and over again when it's already been answered more than twice. Great video
And quit using high performance plug wires. They are junk. Stick with factory 7 mm wires. Trust me. Your not getting more performance your allowing excessive voltage through to the distributor ignition system. That coil has a coil module to control output. It’s mounted on the coil bracket.
Thanks for making videos about this problem. The exact same thing is happening to mine. Beyond frustrating. Anxious to see how you solve it.

Yeah, but these weren't burned, they literally snapped off. So weird.

Thankyou so much for your video. My 99 is doing the same dumb crap.
You’re going to want to watch the video that comes out tomorrow morning. I think I finally solved it.

nothing like persistence ! glad my 2000 has not been as much of a problem.
Lucky!
keep an extra ignition control module on hand....notorious for going bad
Good reply to ignition issues. However. Theirs a timing mark on the crank pulley. Mark it like old school timing adjustment. Put the timing light on #1 spark plug and check to see how far advanced or retarded timing is.
Twisting the dizzie doesn’t change timing. Timing is done via ecu and crank position sensor.
Exactly. So why adjust distributor. The timing mark at the base of the distributor marks DTC or number 1. It should line up with rotor point as well. Just saying that if you have a timing light you’ll notice it’s fixed and controlled by pcm and ignition coil on the coil itself. Also. If the cam is advanced or retarded because of slack in chain then so is the valve timing.
Because twisting it affects where the cap is, rotationally. The timing is not affected but by twisting it the spark is shorter. Watch the video.

Spray some anti moisture in the inside the distributor I forgot what it’s called they sell it at autozone or online fixed my problem
Wait for the next astro vid, I have your solution

@@HeavyChevyGuy Literally used a billet distributor from the forums, dude. The problem is the mounting. Stay tuned for next vid, you'll see.
