Ok....so i just dropped a rebuilt 350 motor into my 86 IROC. It was turning over but not starting.....so i went to adjust the timing on the distributor and when i went to start it again...nothing. I have checked all of my connections throughout the whole ignition and cant find anything.....can anyone help me?

Fuel/Air/Spark
Air is probably not an issure. Do you have fuel getting to the engine? Is the timing correct?

Yes...fuel is getting to it....it just isnt turning over

Is this a freshly built engine? Not some crate? Is the timing set lined up dot to dot? If yes, was the distributor installed pointing to #6, not #1?

Make sure youre not 180° out on the dizzy.

Make sure your getting power to the small terminal with the key in the crank position. Do you even have 12v to the big terminal. Easy way to check that without a meter is to use a screwdriver and connect the two terminals.

if itis a tpi check the distributor wire and the wire under the back of the tune port as they plug into each other .i learned this the long time wait way good luck

Are you by any chance referring to the wires going to the ignition module from the igntion coil and the ECM.

P.S. don't get confused and connect the harness for the MAT into the ignition module instead of the ignition coil harness. The connectors are the same.

yep thats the one it took me amonth to figure that out the only way i did was by talking to preevious owner

First, as said, make sure you're getting fuel/air/spark. Next, check to be sure you're getting spark at the right moment- it's very easy to be 180 off, or even just out of sync. Next, if your car still won't turn over, be sure your valves are properly adjusted. That was my problem. Other than that, you're set. All it takes for a car to start is fuel, air, spark, and compression. Many people forget about compression.
