im having some serious issues with the car. its throwing these codes

po174
po336
p1641
p1642
po161

when i try and start the car, i have to prime it like 6 times, and i have to stomp on the gas to get it started, then when it starts it runs fine for like 20 minutes, then it starts chuggin when i hit the gas, throttle response gets bad and there is about as much power as a v6 mustang. then when i drive it and stop somewhere and shut it off, it wont start unless i let it cool for like 2 hours, i am completely lots and would love some help.

could and problems be from my new holley 155lph fuel pump?

i cant handle dring my jeep around anymore please help

thank you.

 

po174 - Fuel Trim too Lean (Bank 2)
po336 - Crankshaft Position Sensor A Circuit Range/Performance out of spec
p1641 - Fuel Pump Primary Circuit Failure
p1642 - Fuel Pump Monitor Circuit High Input
po161 - O2 Sensor Heater Circuit Malfunction (Bank 2 Sensor 2)




Your fuel pump can't keep up. Why you installed a 155 lph is beyond me anyway. The problem seems to be fuel pressure though, get a fuel pressure regulator. Also make sure the pump is installed correctly. Replace the bad O2 sensor and crank sensor, and you should be good to go.

 

i thought the fuel pump was an upgrade

 

The stock pump can flow 155 lph AFAIK. Either way, I think you somehow messed up your installation. Your motor isn't getting enough fuel, which begs the need for an adjustable regulator

 

is there a fuel pump relay or something that could have gone bad or something?

i just replaced the crank sensor, i think that one is showing because of the cam i put in it, has anyone else had this problem with the cc-305 cam?

 

what would cause

p1641 - Fuel Pump Primary Circuit Failure
p1642 - Fuel Pump Monitor Circuit High Input

bad pump, does it have a relay?

 

Don't know where that info about fuel pump is coming from, but the codes are for the fans:

P1641 Fan Control (FC) relay 1 control circuit
P1642 Fan Control (FC) relay 2 and 3 control circuit

If you have a manual fan switch that is not wired in with some extra resistors, it can cause those codes.

 

can o2 sensors cause that many driveablity issues and stating issues?

 

and there is also no pressure in my gas tank
