I have a 1989 Astro 4.3L engine 80,000 miles. A month ago the van ran fine and turned over fine. All up until I decided to change the intake gaskets. I changed the gaskets put everything back together and then tried to start the van up. The van would turn over but then wouldn't start. As I would try to start it the engine would cough as though through the air filter it was spitting gas. Some one told me it was the timing. So I then reset the timing, while I was under the hood turning the engine by hand I noticed that two wires were exposed one was the ignition switch wire and the other was some sort of positive wire but I don't no what. Mistakenly I touched the two wires and the engauge the engine. But instead of a crank I got a ringing sound as though the batteries ground wire was not grounded to the frame. Thinking nothing of it I then finished setting the timing and tried to start the the van (I taped the loose wires by the way before I tried to start it) The van would not crank when I turned the switch nor would the starter ingauge at all. I tried to bypass the start, at first I got only clunks, but then after a few tries the starter wouldn't even clunk anymore. Now the starter dosent say anything either when I bypass it. I change the coil pack, the starter the ignition switch the and ECM and still I get nothing, I don't think its the belt because as I rotatethe engine I can see that it rotates the distributer. In doing this I found out that I am not getting any spark in the distributer cap and their is no power at the spark plug wires. SO I no the problem is electrical. I am lost hope the motor is not seized but as I said no spark at the distributor. Please help. Maybe I overlooked somthing
have the same problem?
