Engine Turns, Wont Start

Saw some previous threads like this but was hoping that someone might have information that could help me out.

1995 Taco V6 Manual- 255K

Engine turns over, but it wont start. I have verified the following:

- EFI Relay is functioning properly
- Circuit Opening Relay is functioning properly
- Fuel pump is functioning (not fuel to engine though)
- New Fuel Filter
- New Starter
- Battery Level is Good
- Fuses are Good

When i put the key in and turn to the On position, i can see the Circuit Opening Relay click on, the EFI relay click on and the Check Engine Light come on. A lot of the threads I have seen mention the CEL light not coming on and offer advice on how to troubleshoot that specific situation.

I also tried cranking the engine with the high beams on, and they do dim.

 

I clean out the intake and it started momentarily on the cleaner. Not sure why it is not getting gas.

Only obdii codes are from the MAF because i tried starting when it was disconnected.

Since obdii works does this rule out a bad ecu?

 

Sounds like maybe the injectors aren't firing. Maybe take a spark plug out after cranking it to see if the cylinders are wet with gas.

Possibly a very weak spark and somehow the cleaner had an easier time igniting.

ECUs are pretty reliable on Toyotas, so you're better off checking other things first.

 

Check coils

 

plugs?

 

Hey guys. I too am having similar issues.

Checked efi and open relay both make clicking sound when swapped at the fuse box.

What fuses are there to check?

Also getting 12 v to pump, and pump works when connected straight from battery.

No fuel is primed tho. Checked by cracking fuel filter to pump and cranking.
