Today while driving home from work, my '03 Tacoma just died while cruising along at 65 MPH. No noise, or other noticeable problems - it just died, and I coasted to a stop as quickly as I could to the shoulder. It has the 3.4 V6 engine in it, and automatic trans with 4WD trans case.
Thinking the worst, I took the top of the timing belt cover loose, but as far as I can tell it's ok. Checked for CEL codes, and there were no errors codes current, or otherwise. Did a little side of the road Googling, and was thinking maybe fuel pump and/or fuel filter ot maybe fuel pump fuse and relay. Had my wife get both, and a can of starting fluid and bring them to me. Tried a shot of starting fluid in the intake, and still nothing. I'm still going to replace both due to age and mileage, but since the starting fluid did not work, I think I can rule out fuel problem. Still need to check fuse and relay, but again - starter fluid didn't work, so I think ok here. I've got a strong crank, but nothing more. Gas was recently filled, and still about 80% full.
Voltage at the time was 12.5 volts, measured at the battery. I have a K&N oil air filter, and it was recently cleaned, and re-oiled. The MAF may need cleaned, but can't see how it would keep it from starting without throwing a code. The truck has 405K on it, and has had great maintenance - Pennzoil Platinum and Fram filter every 20K to 25K miles. Engine didn't have any lifter noise at all, ran like a well tuned clock. I'm due on the timing belt (I change at roughly 100K instead of the 125K recommended interval), so I think I'm good there.
A/T Temp light was also on, but not sure if that is related. AT has nice red fluid, at proper level, engine oil is a tad black (time for a change), and antifreeze looks ok too (even though it was a little low).
I'm new on this forum, but not new to working on cars/trucks. I've searched the forum, and if there is another similar post, I didn't see it. I'm low on time and cash to get this fixed, so any advice would be welcomed.
