I know a few of you guys have done a 3.4 swap into the older Yotas, so maybe you can help me. Instead, I swapped over a 1980 body onto a 2002 Tacoma chassis, complete with drivetrain, chassis, ECU and wire harnasses, but she won't crank.

There is no 12V at the connector to the starter solenoid when the key is turned on, so I hooked up direct 12V straight from the battery to this terminal, and she started fine.

I have checked the starter relay, and not only does it click, but it would start my other truck, so I know it's fine. Also checked the park/neutral switch, and it's fine. Also swapped bateries, and either/or would start my other truck, but not this one. The check engine light does not stay on once I start it with direct 12V to the starter, so should have no codes, though I haven't hooked up the OBD. Checked all the fuses.

So, I have no signal between the starter relay and the solenoid. The solenoid doesn't even click, yet she would start fine with direct 12V.

Any idea what kind of wiring issue I have that would prevent there being a 12V signal to the starter?

Thanks

Check yer fuses.

Trace the wire from the relay to the starter. You have 12 volts at the relay and none at the starter. Find some point in between and test the voltage there. If you have voltage there, check between there and the starter, otherwise between there and the relay. Maybe a connector pin is loose or a wire broken some place.

And, we need more information. Because...

Thanks for the advise guys. I feel like an idiot. It was indeed a loose connector between the relay and solenoid. The one just below the engine bay fuse box on the Taco's.

I will post some pics once I have the hood and fenders back on there in a few days. Should make for a dependable, reliable old truck.

Thanks again.

Shoot, take a couple pics before throwing the skin back on so we can see your fitment. <img src="/forums/images/graemlins/smile.gif" alt="" />

Okay, how about I post some before, during and after pics in a few days, so you guys can get the complete picture.

Heck yeah, can't wait to check it out.

Also.... do you have gas in it?
Clutch "all the way in" switch? i know my buddies 80' doesnt have one... maybe u need to add one? my 89' does nothing unless u have the clutch in all the way (unless u hit the clutch start cancel switch)
