02 Suburban 2WD LS 5.3L Won't start (ECU, Ignition, Starter?)
What's up guys, I'm new.
checked pages and pages of posts and didn't see anything specific to help troubleshoot and I wanted your help.
3 weeks ago I started my Burb and my
cluster went bezerk. Once it warmed up it was fine. Then this week I went to start it and it was almost completely dead. I had spitfire starter click and it eventually went dead.
- New Battery last month
- Jumpstarted and charged for 30min & nothing
- opened under hood fuse box, reseated everything and it started.
So I went to store and came out and I get the one click start and got towed 😫
This morning I disconnected ECU, checked for intrusion and cleaned the seals and reseated (still nothing).
All the symptoms seem electrical, so I don't think it's the starter. I had my alternator tested last month hence the bad battery for new.
Do you think it could be my ignition switch or still be a bad ECU issue?
Still have juice and car really seems fine other than it won't start.
I'd appreciate y'alls help troubleshooting before I take it to a mechanic.
