2007 1500 4.7 cranks wont start

[combs155]

Looking for some help. I have a 2007 1500 4.7 with flex fuel with about 257k. Just purchased it less then 2 weeks ago. My son was driving it and it died on him. Could not hear fuel pump kicking on. I was able to use starting fluid and it would fire up but not run. Guessing it was fuel pump. Replaced pump cranks and wont start, replaced Cam, Crankshaft sensors and all new plugs. Tried starting fluid again with no luck. Had mechanic scanner hooked up to it and had no communication. I was able to turn the key 3 times to get codes on dash no code were present. I just ordered a ecm thinking its bad.

Any suggestions

Check wire connector that feeds fuel pump under driver side firewall. Had similar problem where fuel pump would work sporadically and fount the connector was coming apart

I can hear it kicking on on the rail if I push it in fuel comes out

If you push what in…the connector? In that case there’s your issue

Sorry the schrader valve on the fuel rail

Update replaced ecm it starts but runs really rough and code 0174

That would be a Bank 1 lean code. It could be bad injectors, an exhaust leak, etc.

Thanks I just can’t seem to win with this truck. Bought it for my son it’s his first vehicle

Back to a no start again i seriously hate this truck now

Sounds electrical. I’d start by checking if fuel pump is getting power

You can hear it kicking on I tried using starting fluid with no luck also

update its alive finally. Bad oil pump causing no pressure to gauge. ECM was damaged replacement was good. Changed out timing chain and lifters runs great so far

 

[combs155]

Oh I hate this truck back to a no start not hearing the fuel pump kicking on

I think I’m having this problem now is this located inside the cab and maybe a description if you can please

No, it’s under truck near driver side firewall. One side runs up into engine bay, other side run back along frame rail to fuel pump.

Awesome thanks I just re-read some posts and saw this again I just had body work done on that side so I’m thinking maybe a wire issue now thanks for the help

No, a 171 is a bank one lean code.... 174 is for bank two!
