If I were concerned with EPA regulations, I would have the system evacuated, tagged, and disassembled.
If I weren't concerned about that, I'd invest in a pair of bolt cutters and clip, clip, clip.

Crank sensor was what I thought the problem and I changed it. (It was junk) but the new one in,I I put a test light to the plug coming off of it and it lit up, then I have 12 volts to each prong on the ignition control module but and I changed out coil packs for known good ones and wires and still just cranking. I have spark to prongs on ignition controls module but nothing past it. Magent will fall off crank, the magnet is on crank on on 3300. It's in switch on most other GM models, . It needs right gap as well real close to .050. Also need a good cam sensor for spark too. |

So we tried starting the car after it was jacked up at a downward angle and it turned over but no fire. So we sprayed ether in the intake and it fired. And then we accidentally cut and inline fuse for the bunch that came from the computer to the relays. Could it have been an inline fuse to the injectors and that's why it won't fire?

That is your problem |

That's exactly what it was. Dug through the mess of wires and connected it and it fired right up

Well I believe I have it figured out. After pulling off the balancer again and seeing the crank sensor chewed up again, I found out that the guy had replaced the original harmonic balancer... but the new one wasn't the same. I'm thinking maybe he thought the 3800 was the same as the 3300? But regardless, going to Pull apart to get the right balancer and I'll hopefully have some good news for ya later

How hard is it to get to and weld the spiders in a 2.8?

Does anyone have the coil pack order for a 93 century? I can't find an exact one I keep seeing all different ones. It'll backfired once then just crank and it'll start on starting fluid for a second then stall out. I have the firing order
63
25
41 and and 63 is the front coil. I have a weak orange spark though so I'm assuming the firing order is wrong.

That's the order I have now. But still weak orange spark. It's almost like I'm not getting fuel somewhere, but I thought it might have just been the wrong firing order causing it.. but if the firing order is correct then I'm not too sure where to go from here. Any thoughts?

I would guess If the conpomemts that fire your coils all test out and don't have any bad wires, ecm. It's supplies the 5 volt to run all the sensors and stuff that is needed to run. Just a guess but would be my next attempt.

Could injectors be stuck?

Could injectors be stuck? Could be bad injectors, they are same unjectors as 2.8/3.1 |

It's looking like no injector pulse.

I can pull a plug and see if it smells like gas when I start it or pull an injector and see if it sprays when I start it right? Are those legible ways to check.
