Engine Mechanical problem
1995 Chevy Blazer 6 cyl Four Wheel Drive Automatic

Ok here goes, first off started to be a fuel problem. No power was getting to the fuel pump, turned out to be the fuel sending unit. Now the fuel pump engages. Now comes another problem. I am getting no spark. Engines turns over but wont start. Let me say that the crankshaft sensor, coil, ignition modues, oil sending unit and fuel pump relays are all new. What other problem might there be that wont allow it to get spark? Any help?

Hello,

Look on the fire wall about center... There should be a ESC Module (Electronic Spark Control) it looks like this.......

Thanks for the suggestion, that is one thing that I didnt think to check. But just for the heck of it I took out the new Crankshaft Position Sensor and put the old one back in. The thing started right up. Turns out I got a bad one from the parts store. But seeing as I got the Blazer given to me I figure its worth spending a few bucks on new parts.
