No power at ECMB on fuse panel

No power at ECMB on fuse panel

Postby Chevyguy713 [OP] » September 16th 2012, 6:31pm

1994 Astro EXT 4.3L TBI (Z engine) So got a real jerker of a fuel/electrical problem here... no power to ECMB at fuse panel... fusable link gone at fire wall? Van has been sitting for a few months. Dropped tank replaced fuel pump, fuel filter, fuel relay (firewall). Check all electrical connections? Oil pressure sensor is the only thing not replaced, but no power at the fuse panel? My understanding was the ECMB power at the fuse panel came straight from the battery. Suggestions to prevent insanity? :banghead:

??? Fusible link gone at firewall ??? What do you actually mean ? Is the link fried, MIA, or what. Have you checked for voltage thru the

f/l ? and down stream of them (the red wires that continue the circuit. Open up the large wire loom in back of the battery, and see if

one of the power wires broken open due to corrosion (battery acid related). I had this happen two times. Looked like a gnarled discolored

nodule on the red wire. Cut out the bad boy, and repaired with solder and shrink wrap.

Yeah it appears the fusible links have all been snipped out and shrink wrapped. Going to check that thanks, I am correct to say power at ECMB at panel all the time? Thank you I'll get back to you. :bouncy:

Amazing!!! Bad wire in the feed at the firewall didn't see it until I almost gave up... soft browned orange wire... cut it shrink wrapped the sucker and boom! there we have pump power. Spent tons of cash, tons of time, hours of blogging, THANK YOU, good for another 450k!!!!!!!!!!! These vans do rule after the bs gets worked out! :bow: :banana: :sleep: :ty:
