No start

I have a 96 tacoma 2.7 5 speed I was driving from Tennessee to Missouri and stopped for fuel ,filled up and truck will not start .i did notice when trying to start the check engine light no longer comes on with the key I'm getting to spark and no fuel I'm thinking possible pcm any help would be great!!

 

Codes?

 

No codes cannot communicate with pcm I've been checking power and ground but can't find the schematic I'm needing

 

I found the schematic on the pcm I have power and ground so I guess the pcm is bad

 

If anyone has a pcm with part nunber 89661-04190 I would appreciate it

 

Welcome aboard

 

Welcome and good luck getting this sorted.

 

I'm glad to be on here I believe the pcm is the culprit I'll let you no when I replace it

 

It's weird that it would just die at a fuel stop.

 

I agree

 

There's more to diagnosing a bad PCM than that, isn't there? I guess I'm just seeing what's here in the thread, but pulled over for gas and filled up and now truck won't start and you verified juice and ground at the PCM so PCM is bad? I'm not saying it isn't that, I'm just thinking there could be a few other culprits to check before jumping to a bad PCM right?

 

You are correct sorry I'm new to this I checked all the wiring and there is nothing coming from the pcm to anything else no signal at all grounds are all good there's really nothing left to check

 

No, I'm not correct man, I just don't want you to spend on a PCM quite yet.
So just for clarity, you turn the key and hold to start and what happens? Does the engine turn and turn but not fire up? Does the starter just click loud once and then nothing?

 

Or maybe I misread, you already checked all of that stuff like fuel pump, etc?
You double checked fuses, under the hood fuses as well?

 

Yep I checked all fuses engine turns over good but no fuel and no spark thank you for all the input I don't want it to be a pcm but it really looks like it is

 

When the knock sensors fail they can cause no start condition. I think same with crank position sensor.

 

I thought the same thing but when you turn the key on the check engine light doesn't come on but the rest of the lights come on so that tells me the pcm is not firing up to do the self check

 

Oh I missed that I guess. Gotcha gotcha. Sucks. My bad.

 

No problem I appreciate all the help it only has 306000 miles on it

 

Even then, it's just so rare for the ecus to fail. But it does happen
