What's worse it's an intermittent problem and don't trust it any
further than I can push it
'Bout two weeks it started fine, but when I turned on the lights, the
engine died--no fuel to the TBI
Didn't make the connection for a while as I swapped fuel pumps and
everything was fine (for a while)
Died again a few miles from home and this time I noticed no
headlights, no tail lights, no interior lights, no fuel pump, but will
Towed it home and discovered the fuel pump would work when connected
to a 12V source
Swapped the headlight switch....... no luck
Took apart the engine wiring harness to the fuse block, didn't see any
corrosion and everything worked again until yesterday
Have power thru the fuse block from the two hot wires
Plan on going out today to check on just fuses which have power and
which don't with ign switch on.
Anyone else ever have this c**p happen to 'em?
Must be a short somewhere but where?
Take a good look at the condition of the connections at grounding points,
particularly where a cable is grounded to the frame. Corrosion is sometimes
hard to detect and it can drive you to wit's end. Also, inspect the
negative battery cable terminal. I've seen corrosion build up beneath the
insulation (where it's nearly impossible to detect) and cause a poor
electrical connection. Good luck.
Thanks for the reply
Finally found the problem after taking out the entire dash.
(Like they say: "Kids, don't try this at home")
Turned out one of the two hot wires in the connection block between
the engine wiring harness, thru the firewall and into the fuse block
just decided not to connect.
Nothing was visibly fried, corroded, broken or otherwise fouled, but
Picked up another wire and connectors from the local Pick n Pull and
Only took about 5 hours to get everything back together.
I'd hate to see what a shop would have charged me to find n fix it.
Probably would have sold me an entire wiring harness, but wouldn't
have taken two weeks to figure it out
I have seen that a couple times. The usual problem is that the pins
didn't get seated fully when the harness was made. When first built they
connect but a few years of hot/cold cycles and rough roads and they
become intermittent. It's a PIA to find, because as you discovered with
yours. Nothing looks like it's messed up in the block.
I have also seen more than one where the fuse connectors LOOK fine but
they no longer pass current. Pull the fuse block and they still look OK
until you actually test the clips.
