I have an '80 toyota 4x4, and a 94 toyota pu 4x4 that I got for a donor truck. pulled the engine out along with the entire engine bay harness all the way to the ECU/ computer and cut it 5" on outgoing side. I have wired the fuel pump into a keyed power. It will turn over but not fire, I'm wondering if I missed a wire or ground. I don't read diagrams well,
so i'm wondering if anyone one can tell me which wires coming out of the computer need power or grounded?????
thanks for any help!

 

Not sure based on the wires but the EFI system needs power.

Did you put the EFI fuel pump into your tank?

When it comes down to it all you need is fuel and spark to fire a motor. Find out which one you aren't getting first. Also, make sure the AFM is connected. The 22re won't run without it.

 

LOL thanks for your thoughts! I took the fuel tank out of the 94 cause it was also larger +gal.
I forgot the positive Batt wire going to the ECU everything else was hooked up. wired that one wire and it started right up
