If it spits n sputter, its gettin a lil spark, just not enough to get a clean full burn.

Just got it home this evenin been workin 12s so hadn't had time to mess with it much. But the more I mess with it the more I'm thinkin its the ignition. When I got pulled home none of the gauges on the dash worked(speedometer gas gauge battery gauge) so I'm thinkin its the ignition cause the radio ain't even gettin power now... so I'm gonna go ahead and check for spark tomorrow mornin if not ill just get a hole new steerin column. If any of ya'll know of someone with an '88-'98 Chevy or GMC parts truck in the south Houston area gimme a shout or pm me...

Sounds like ur crank position sensor or cam position sensor.
Could be ur computer but I'd try that first.
No spark could be caused by those sensors because if no rpm is read it won't
Throw spark.

The only thing that's gettin electric is the lights and starter. No lights on the dash work an its not throwin any spark. Wouldn't that be a component in the ignition not givin anything power?

If dash or nothin working
Go with PCM or ignition but most likely its PCM
Txt me 254-366-0315
Let me see if I can find info on the PCM fuses and relays

If u aint getn even dash lights, its more than ignition if its the ignition to begin with. If im not mistaken, the gage n dash cluster are solid circuitry. There may be a good bit of corrosion on the terminals n possibly a lil ark n spark across the boards.
As for ur crank n cam pos sensors, look near the hormonic balancer for a sensor near it and the cam sensor will be at the front or back of block or head/s where the cam/s will be or even on the center gear where the chains go from the center gear to the cams. Looks for a sensor or wires goin into the timing cover. Its kinda hard to discribe w/o lookn at that tck or 1 similar

Other than electrical here's a few things you need to know. Air fire fuel. Without any of these you won't have anything. If its turning over first thin yo check for would be enough fuel pressure. You can buy a cheap giraffe or rent borrow one. If you fuel is good check to make sure there is no restriction on air flow. Rats nest dead animals in filter or air duct etc. If that is good check to make sure you have fire. First start with the COIL wire coming of your distributor to see if your getting fire from the distributor. Make sure your ignition wire is plugged into the distributor. Google had wiring diagrams. Next if you have enough fire to the plugs you could always do a compression test. There are different ways of goin about this which I can explain in further detail. This will tell if you have enough compression. There is also other ways of performing pressure tests to see if you have broke valves or what not.
That's just the mechanical side of it.
Also in that year model the most common thing about going out is is the ignition module that is on top of the distributor. Over time moisture and heat will make them go out. Best way to check is go to the junk yard and get a few and try them out at the parts store they are about 40 bucks. Any questions just get with me in here

I would try the ignition module in the distributor first check for fire and then go wit PCM. Igniton module is way cheaper than PCM. |

its not gettin any fire and there's no corrosion wwitin on a buddy to bring me my tools back so I can see if there's any power goin from the ignition to the pcm |

check fuel pressure - its a 4.3, probably has spider type injectors. The crack in the intake and you lose fuel pressure and volume.
After you confirmed your getting enough fuel - check for spark, and if it will jump over at least 30 thousands of a gap

Been workin on my truck all day changed the tumbler ignition sensor and ecm still nothin the ecm was burnt up I could smell it when I pulled the glove box off its gettin power to the dis cap but not makin spark and the radio and cig lighter ain't workin so I'm guessin a short or popped wire somewhere. That's on my 95 4x4 with the 350 tbi
Now on the 98 I changed out the cpm and reset it and still nothin tried takin it back to parts unlimited but they closed as I was pullin in the parkin lot. Think I'm gonna change out the hole ignition.
He!! of a time for both my vehicles to $hit out on me. supposed to be up in Huntsville Wednesday mornin and I still have a hole houseful of crap to put in storage.

Hey I don't know if have fix ur truck! If not is the engine light on on the cluster? If so get someone to hook it up and pull the codes. If it's not on, when you turn the key to the on position an the gauges on the cluster are jumping back and forth will the windshield wipers work or will the windows roll down if they are electric! But what I have read from your question it sounds like the ECM/ECU is bad! You can pull it out and have it checked. It's easy to pull it out! Just pull the glove box it's two screws just under the dash. Then you will be looking at the computer. Also you might pull the computer and on top of it there will be two screws pull them and make sure the chip is in it or make sure it's pushed all the way in! Just something to try! Let me know!
