Charlie, Do you have any idea if there are companies out there that will refurbish my old ECU. I'd love to have a spare. Andre

ECU fixed it It was indeed the ECU. Used one I bought on ebay came in the mail yesterday. The truck fired up with no hesitation. It's running really well. Couple things I've learned: the OBD to ECU communication line will "idle" at 0.45V (as you indicated, PhattyDuck.) When the ECU is talking...

Update: 2/27/26 I've verified the mechanical timing. The belt is good and the timing marks are good. The cam and crank sensors are good, clean, clear of obstruction. Definitely think the ECU is bad, but I’m baffled as to why or how? Other than the 'Linking Error' and the IAC valve clicking...

I did reattach the intake before trying to start it with the IAC valve unplugged. I didn't want the MAF to kill the engine with low readings by leaving the boot off. I've tested all the grounds I can find. Both brown wire grounds on the ECU (there might be more?) both grounds on the OBD plug...

Hey, yeah, I am going to check the timing. When it cranks it sounds normal but you never know. The timing belt isn't broken. If it has slipped a couple teeth I would think it would still start and run, even if poorly, but that is a good suggestion. I was measuring the ECU communication line...

more info Thanks for the reply, Phatty. I pulled the ECU and inspected. Looks fine, no loose pins, the inside looks clean and new, no corrosion or burn spots, no loose parts or debris. The OBD port has 4 wires. Two grounds (pins 4 & 5 - tested good,) power (pin 16 - tested good, batt...

Maf I see it. It definitely has a MAF sensor. All jokes aside, the MAF sensor wouldn't be clicking. Also, unplugging the MAF sensor doesn't stop the clicking. Also, if the MAF sensor is bad it would start and die.

'96 4x4 Automatic: ran fine until it just didn't run at all. No rough running, no CEL; it was running fine, I parked it and a couple hours later it wouldn't start. The battery, fully charged, turns the engine over fine. Lights on the dash seem normal. No blown fuses. No clicking relays. Two...

Yeah, nice video, I watched it several times studying up for this job. I wasn't planning to replace the knock sensors because they weren't throwing a code or damaged. The wiring harness came apart but initially the sensors were fine. Unfortunately I chipped the connector on one of them which got...

I believe you, but not according to my local Toyota dealership parts desk. NBD, my 4Runner is back on the road and not leaking, so it's kind of a low priority project at this point.

Lower air intake gasket - Google Photos I just did this over the holiday. It was easy until it was very, very hard. There's been a bit of antifreeze in the valley of the engine for years now (seriously, I know, I'm horrible.) Until a few months ago it was just a bit. It would all burn off once...

Mind blown This thread is kinda blowing my mind. God's work, B. You're doing God's work, lol. You started welding in 2015 or started welding these frames up then? Just curious.

Coolant hose I see there's a coolant pipe under there. I do not believe it's leaking. I'm debating replacing the o-ring. Hate to disturb anything that's working though, lol

I have coolant on both sides of the valley in between the intake manifold and heads. So, I'm preparing for gasket replacement. I have a couple questions for anyone who's been in there; are there other things I should look at replacing "while I'm in there." Second, can you take the manifold out...

J/B 3 is a junction, not a box really Thanks TK, My left rear blinker went out but the bulb was good. I measured 1.5v at the socket (for reference, the left hand one was blinking at 5.5v.) I had continuity to ground from the socket.The front right was working so I figured the switch on the...
