i have a 2000 tacoma 2.7L with no crank no start. i believe the 5volt reference is shorted.assist me

battery is good. alternator is good. starter is good. check engine light won’t illuminate as you engage the key to the on position.

 

Welcome to Tacoma World. Do any other lights come on? Have you checked fuses? When did it last run? Have you done any repairs to it for this problem?

 

That would my questions too, What other lights, if any, come on when the key is 'on'? Headlights, turn signals, emergency flashers, etc? Any power to the OBDII port? The check engine light could be burned out.

 

I use to have a 2000 tacoma that did that. Ended up being a severed wire on one of the coil pack plugs. I'll add it took me 2 weeks to find it, after pulling bed and replacing fuel pump thinking that was the problem.

 

fuses appear to be okay and relays. i’ll check all the lights that illuminate. the last time it ran was a week ago he pumped gas at a shell. it’s been having crank no start issues since. only the alternator was replaced and a new battery.

 

Clutch button may have ratteled loose. On my 02 I have two of them. Top and bottom

 

The powertrain control module (PCM) is grounded on the intake manifold. There is a group of brown wires with a ring terminal, 6 wires IIRC. I would check those first. The CEL HAS to illuminate during the bulb check routine of the key on position.
