Truck won't start - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Got a problem with my truck. While driving around Thursday I noticed the amp meter drop to 0 three times for about 10 seconds before coming back up. When I got home I shut the truck off and when I went to start it, it was dead.

I have a powermaster one wire alternator that's only about 1 year old and I thought I might have a problem with it. I tried jumping the truck but nothing. I charged the battery fully and it tests good but still nothing. When you stick the key in, the dash lights come on and it buzzes weakly but won't start. To make sure it wasn't the battery I swapped it with a brand new one I had and It does the same thing. There's not enough power to turn the headlights on or roll up the windows which seems like a battery problem.

I tried jumping it strait to the starter and was able to get it to turn over for short bursts before it stopped but it wouldn't start.
Anybody have any ideas for me to try?

Make sure all battery cables are tight and ground wires going to frame also.

im no electrical expert but sounds like you may have had a short somewhere. popped a fuseable link perhaps? im sure others will chime in with more info.

these trucks are notorious for the inline fuse up on the firewall for going bad which will cause exactly what you are describing it is located at the top of the firewall near the middle of the truck is just off a connector block there hope this helps

If the battery is good, then my guess is battery cables.

The inline fuses at the firewall and starter look good and I have 12.4V at the battery, the starter and the firewall. And I grounded it both off the battery and frame so I don't think its a ground issue or battery cable issue.
Any other ideas?

is the solenoid at the starter ok

just an idea other than that sorry no clue

check your main power cable to the starter make sure it didnt touch the exaust maniful and is shorting there i had a problem like that before and that is what i found it was

also might be the ignition switch in the column but I still think its an inline fuse maybe the inline fuse down by the starter good luck electrical can be very aggravating

Figured out what the problem was. The ignition module in the distributor was bad. Got a new one and it fired right up.
