Hi all new to the forum and new to me 1995 4Runner owner. Got a nice truck V6 3.0, Manual Trans. Was running yesterday and had 2 codes when I picked it up 25 and 71. Looking under the hood it had broken wires on the ECU/exhaust Temperature sensor so I replaced the sensor. I Pulled the 20 amp ECU fuse to reset it, and now the vehicle WILL NOT START. Turns over all day, but no fire. Checked all fuses - good, There is power at the fuse box to the ECU, not sure how to check power AT the ecu. Only other thing I did was change the air filter - wondering if I tweaked something on the MAF?. Re-attaching the code jumper yields no check engine light at all, no solid, no blinks, NADA. Any ideas on what else to try? Had the truck 1 day and I broke it. This one is baffling me.
