This could be a real stretch but I had a similar problem where I had trouble getting the truck to start every few days where I had to turn the key a couple times, then would stutter when first going, a couple times just stalled out. Drove myself nuts with hoses, fuel pressure etc.
Had a rusted battery terminal screw. It was being shaken when driving, caused the battery not to charge properly when driving. An easy test is to jiggle each wire separately(obviously do not create a connection with yourself and the car). You will hear the power go on and off.
Again probably not it but was listed as one of the first things to check and I ignored it because had one of those duralast batteries

Oct 04, 2009 (1:58 pm)
Hey guys, my blazer died and wont restart. I smell gas after 2 turn-overs,but cant find any spark from the coil. also every time I turn the switch, my ECM/Batt fuse blows. Any ideas?

I think it might be the crank position sensor which is located on the front of the engine near the harmonic balancer and main pully. Try this first, its cheap! 20 dolars if that. if that will not work then its the ecm, it being bad will send mixed signals. But i would try the crank position sensor first.

I need to keep this truck running but every time it gets hot, it stalls out. Unless you have your foot on the gas and the idle high, it will stall out every time. Does not
do it when its cold . I have had a new motor put in , rebuilt carb (for high altitude)
new fuel pump and water pump. Truck should run great......does for about 10 minutes and then it stalls. Any suggestions

New coil? You are describing a very typical coil failure, and I doubt the new engine came with one.

Yes sir, we put new coil, plugs, wires, I am wondering about the EFE relay switch, mounting on the firewall, it was buzzing ??? so I ordered another switch, when it comes in I will install it. Thanks

Relays can fail in a number of ways. Check the voltage going to the coil of the relay. If it is below the rated voltage (typically 12VDC on a car) the coil cannot fully engage the relay contacts and you will get the buzzing you describe. Usually the coil just fails, but I have seen cases where some of the windings will short and also cause the "buzzing" sound.

I will check that once the switch gets here. Thanks and I will let you know !
#310 of 496 1992 chevy 4.3 v6 won,t idle
Oct 24, 2009 (3:09 pm)
I have a 1992 chevy pickup with a 4.3 v6. When i crank it i have to throttle the gas to keep it running. If i unplug the map sensor it will run at a high idle. I have tested the map sensor and it tests fine, i have even replaced it but that didn't work. I have replaced the ECM, IAC,TPS,EGR valve, fuel filter. I have cleaned the throttle body. I have checked the vacuum lines, distributor, wires and plugs. The vacuum selinoid works fine and the spark control module works fine.I had a diagnostic tool run on it but no codes. I have ohmed out the wiring and found no breaks. Can anyone give me some ideas on what this problem can be? Please help!!!

I have a 95 chevy blazer automatic with a 4.3 vortex. When I drive it the RPMs jump around and then it stalls out if I hit the brakes. Does anyone have any Ideas of what may be wrong?
