ran good at start up, over heating, shut it back down, replace water pump.
battery went dead, jumped off--no good, new battery, turns over great!
will not fire up, no spark at #1 plug.
it has new cap, rotor,wires,plugs,coil, icm,cam sensor,crank sensor.
all fues are good at the box, check with test light.took all wires loose, clean all, grounds, checked inline fuses as well. omhs through coil wire good,

Re: 1196 chey blazer
Overheating could be caused by a stuck thermostat or a clogged radiator not firing on #1 plug could be a fouled plug or bad wire or it may be grounding on the block and your coiil may not have been put in at the right mark

Most likely you have a bad battery. The second option is that you have a faulty wiring and there is a constant load that takes a lot of power, but it does not make a short circuit. Check the electrical relays, maybe it's in them.
I`m positive you have a bad head gasket.I just did one for a friend of mine that had the same problem on his Buick Rondevous.Same motor.These are good motors but they have a tendency to blow the head gaskets.It is usually the back one for the #1 cylinder.Hope this helps.Good luck.
These cars are known for having engine related electrical problems that can be difficult to track down. One dead sensor is sufficient to prevent start up .
It is possible that your problem had nothing to do with the jump start or battery replacement.
Without a full diagnosis anyone not able to test the vehicle will be guessing.
One thing I would do is to check your fuse panels for all engine related fuses such as fuel pump, ignition and fuel injection to ensure these fuses are sound. Check all visible wiring carefully including your battery connections. Carefully disconnect and then re-connect the battery at both terminals.
Your best option is to have the car towed to a reputable repairer that is familiar with these cars so he can run a full check and isolate the problem.
Whether you have blown something in the course of jump starting the car is unknown.
In future, when jump starting these older vehicles always turn the headlights on and do not turn them off again whilst the vehicle is running until after the spare battery used for the jump start has been fully disconnected. Everything else should be off.
mario, try taking the battery cables completely off and cleaning them.
<:AtomicElement>with a wire brush, put them back on and wait for about 15 min. if it don't start by turning the key over jump it off if the battery is still good it will charge if not you need a new battery. watch your voltmeter on the dashboard while it's running. good-luck, ray
I had a similar problem and believe it or not it was the CAT. An easy way to test for this is to remove the O2 sensor right in front of the CAT. Once you removed it, plug it back in while unscrewed from the exhaust pipe and start up the truck. If it runs fine, the CAT is your problem. This is just a guess and it would be an easy and very cheap($0) test. You did not say if the truck was diesel or gas. Mine is gas that was exhibiting the same problem as yours...good luck!
The most likely senario is that the water pump went bad which caused the overheating in the first place. Then after the engine shut down, the water pump seized up. When the engine was restarted, the timing belt started to smoke because the water pump, which runs off the timing belt, was not turning. Since the engine overheated to the point of shutting down, blown head gaskets are a possibility. Put a new timing belt and water pump on it and start it up. If it runs OK, you're good to go.
