i have had problems lately and it only happens on about every 15 starts.. i turn the key and it makes a sucking noise and tries to start and then i stop and try it again and it starts fine. i just cleaned my plugs and got a new air filter and checked for any loose wires. any suggestions??

96 Sonoma won't start, No idiot lights or fuel pump activation by gmcdriver1

I have a 96 automatic 4.3 litre Sonoma with about 139K miles. It has been running good. A few days ago it stalled while idoling, restarted fine without incident. I drove it a few miles, running fine, then I shut it off for about 5 minutes and it would not start. The fuel pump does not go on when the ignition is on. The idiot lights do not illuminate in the dash either. It will crank over but does not fire. Does anyone have any suggestions??
 
Thanks.

something shuts off all electricals. It will start with a jump. Seems to reload (lights flashing on instrument panel). During jump, acts like low battery, but battery checks out. it's a 2002 S10 v6 that runs like a watch except sometimes. Any info prognosis or advice?

Chevy s10 1996 here and a very similar problem. Pepboys charged me $160 to tell me that something was wrong, but they didn't know what it was. Thats what I told them when I walked in there and then they charged me for it? LOL
 
Bought it in September when it was still mostly warm. The rain doesn't seem to cause it to not start, but as soon as it got cold it started having issues. Its automatic and I'm more used to driving manual, but once its started at least I know that it need more gas to keep it started. It shimmies and shakes until I get it moving, then maybe 100yards later it evens out. Three seperate mechanics think I'm nuts cause it always starts when they try it. Automatic is started just by turning the key right? I shouldn't have to pump the gas to get it started right?

I have read of similar problems. It was cause by carbon collecting on the intake valves and absorbing the fuel on cold start, sorta like no choke.
I thought I would throw this out for you to mull over.
