I have a 1998 Toyota Tacoma with just under 200k miles on it. While on
a road trip, the engine threw a rod. My neighbor told me that if I
found a replacement engine, he could swap it for me. So, i got an
engine, had the truck towed back to the house. A long story short, got
the new engine in, everything hooked back up and it won't start...

After some digging around, we found that there is no spark at any of
the spark plugs. I dug around on the internet and found a couple of
suggestions that i tried. One was to hook a light probe up to the +12
of the battery and touch the 2nd to the left wire on the plug that
goes to one of the coil packs. When you crank the truck the light
should flash indicating that it is sending a signal to the coil to
tell it to fire. No flashing light, the bulb stays dimly lit. I
checked the voltage on the wire and it is approx. 8 volts.

Today a friend brought over his OBD II scanner and we hooked it up to
the truck and the codes it returned were P1300, P1310. Both are
"Igniter Circuit Malfunction". Well, that doesn't tell me anything
that i already didn't know.

The engine sounds strong like it wants to start but just won't. I'm at
a loss and am going to take it to a mechanic but i would really like
to get it fixed myself.

Any ideas what else i could try?

Have you checked your cam and crank sensors yet ?

I check the resistance on both and they where within the limits.

I don't know the engine you are using but I had a similar problem after
doing a head gasket replacement. Check mass airflow sensor for proper
readings.
