Well... I've been racking peoples brains and trying to post for help with minimal luck. After doing head gaskets and manual swap to my 95 4runner V6, she won't start!! The only problem (I hope) is there is no spark. I know there is fuel... Yes I found out the hard way. But my ignitor has no voltage, thus from what I understand there is a wiring problem between the ignitor, ignitor coils and ignition switch. I'm at a loss of what to check or where to look. Has anyone ever had this problem? Any insight? Please help me guys!!

 

Its possible your ignition fuse is blown or your switch could be bad or you could have a broken wire. You have a good grasp on what your problem is. Your way forward is to grab a FSM or chilton manual and look at the wiring diagram. Trace the circuit out and confirm power or lack thereof along the circuit path until you find where the problem has occurred.

 

The injectors, TPS, Dist, Igniter and the AFM use all the same B+ wire.

Follow it backward and look for a split/break.

 

Finally got it running! Such a relief! It turned out the MAF was bad so I stuck in a manual ecu and new sensor and she started right up!

 

Im having the same issue. how did you determine it was the mass air flow sensor???? thanks for the help

 

All I did was Ohms test it. Look in the Hanes manual for the correct readings but between the pins there is a certaint resistance between them
