I have a 1992 chevy 350 that I just put a new intake on and had to take the distributer off to get th old one off and the new one on. The plugs were not in order like they should be 1357 driver and 2468 for the passenger side. So I rewired it correctly and now the truck wont start. What do I need to do to fix this?

I believe the firing order is 1, 8, 4, 3, 6, 5, 7, 2 Is the engine trying to start? Backfiring? Are you getting spark and fuel to the engine?

It is deffinally getting fuel and it was getting spark until I redid the wiring for the plug wires. Now it is not getting anything at all. Im usually mechanicly inclined as I have worked on every vehicle I have had. This stumped me.

Changing the plug wires shouldn't have cause you to lose spark. First, make sure the distributor is correctly installed, the plug wires are correct, and then take the distributor cap off and see if the rotor is turning when the engine is cranked. Maybe it isn't fully inserted. Also, check the ignition module wires to make sure they are still connected.

Let me know what you find.

Double check to make sure nothing is disconnected. There is an ignition moduld in the dist. Check to make sure it is connected. Without it, you won't get spark. Also, check to see if there is power to the coil.

Okay so I got it all running but I now have an oil leak coming from the back of the motor so what do you think that could be?

Glad you got it running. What was the problem? As far as the oil leak, most likely the intake unless the distributor isn't properly installed. I know you don't want to hear that, but there really isn't anything back there that could leak oil. The oil sending unit is near the oil filter if I recall. Double check that and let me know what you find.

Okay I just had to time it but I replaced the oil pressure switch and it is still leaking so do you think that it could be the intake?

The intake, sending unit, valve cover, cylinder head, distributor. That is about it.
