FIXED!! Help, 2006 2.7 cranks but no start. Quit on the road, spray starter fluid starts up.

Installed new fuel pump but still no start.

 

Check fuel pump fuse and relay.

 

Did you check the leads at the fuel pump for power and ground? Fuse okay? Does the 2.7 have a separate fuel filter?

 

All fuses good, all relays good. Installed new pump & cam sensor, no change.

 

Jumped hot wire to pump, it runs but no start. Cranks good.

 

Gas in tank?

 

So injectors? What would take them all off line? Is there another fuel filter/screen somewhere on the rails?

 

Plenty of gas. When I spray in starting fluid it starts & runs for a minute so don’t think it could be injectors. Can’t find a good color wiring diagram for a 2006.

 

Where are you spraying the starter fluid? Through the throttle body?

 

Very valid question. The following thread is a whole diagnostic mess, that ended up being the fuel gauge showed gas in the tank, but was actually out of gas.

Open the fitting on the fuel rail and see if fuel come out when the the engine is cranked. This will at least confirm your getting fuel to the rail.

 

Can’t say that didn’t happen to me on a previous vehicle.

 

Check engine light? I would run it for codes. I'm leaning mass airflow sensor

 

Plenty of gas, no codes

C/OPN Relay? IGN Fuse?

Check all fuses using a meter, don't depend on vision as sometimes it can be misleading.

 

Thanks for wiring diagram, all fuses & relays checked & double checked. Power is good to fuel pump on crank, still no start. Gonna start checking wire connections to eco now.

Why would this rule out the injectors? Not saying it is the injectors, esp all of them at once.

Crack open the rail as suggested to see if your fuel is getting that far.

 

Like I mentioned before. Loosen the fitting and on the fuel rail. Crank over the engine. If fuel is spraying out you have eliminated everything up to the fuel rail. Don’t go over thinking this.

 

Took fuel loose at rail, very good pressure when cranking only.
