This is a discussion on 1988 Suburban 5.7 TBI, Just died!!! within the Technical / Maintenance forums, part of the General Discussion category; I started it up, Let it run fir 5 min, then Pow!!! It just died! Everthing has power, It turns ...
I started it up, Let it run fir 5 min, then Pow!!! It just died! Everthing has power, It turns over, just no fire! I cannot find anything wrong! Checked all fuses and the ECM Fuse was blown, Replaced it and still nothing.
Any help or directions would be Great.
Nope, Fuse is good.
Replaced the Ecm, Still the same.
But now I found that my Headlights dont work.
Start with the basics. Fuel pressure, spark.
I have fuel pressure, No spark.
I think a wire is fried, If this was a older car, I'd say it was a fusable link.
there has to be a wire shorting out somewhere causing your issues. Pull out one fuse at a time and see if your truck starts. Ovioulst dont pull the fuses for the things your truck needs to run. Try pulling the fuses for the lights, wipers, etc. If the truck starts with one of those fuses out then your electrical issues is in that circuit
Could be the distributor or coil.
Here is what i found,There is no power to or from The ECMB Fuse, I ran 12 V to the top of the fuse and she fired right up. So i am pulling the fusebox out.

Traced lack of power to starter, Found a Fusable link smoked.
Glad you found it. Keep an eye on it, that fusible link melted for a reason.
nice job dude i hate electrical stuff, it just befuddles my mind and makes my head hurt when i try to figure them out haha
