No Spark!! 89 blazer s10 tahoe
Hey guys! Well started up fine till i changed the cap
rotor, plug wires now i am not getting a spark, so i bought a new ignition coil and still no spark to the distributor. I checked the fuse box and all is good, seems like i am not getting gas now eithier. What could possibly go wrong with just changing this stuff? Checked the fuel pump relay fuses and there good to. Cranks over fine, distributor, rotor and wires were pretty funky and it started fine, i just dont get it. Any suggestion would be great, Thanks 4.3

Is there spark if you pull one out, ground it and look at it while its cranking? If so I agree with the last post, timing is off or the new parts are not installed correctly, wires backwards/mixed up, etc...

I havent had to test one in a long time but I would ground one lead on the voltmeter and check for +12v on the lead wire to the coil, not the spark output. There should be 2 poles on the coil to check. Here is a cool animated GIF that shows how it works...
