Turns over but will not start takes about a hour to start have to spray carbirator cleaner into the breather and have to pull the fuel pump relay out

This is how fuel pumps act. One day they work and the next they don't. Check the fuel pump. Even a weak pump pressure will fail to start the car. Unless you were in an accident a fuel cut-off switch won't activate.

Also: Start by checking if it's a fuel or spark problem. Take a plug wire off and turn motor over.If there is fire, Take the hose going from the air cleaner to the throttle body off and spray a small amount of carb. cleaner in.If it's a fuel prob.,check the fuel pump relay (under the hood in a black box) (swap the relay out with another relay in the box ) If the relay is o.k., it's probably the fuel pump. If it's a spark prob., start with the coil and wires going to the coil.

This is a difficult problem to solve because it seems like you have fuel that you can see and won't run; and then when you add fuel manually, it runs.

The TPS throttle position switch is suppose to regulate the fuel dumped into the engine..
You may have a dead spot on this switch. Another part, a crankshaft sensor, is suppose to report to the ECM about its' revolutions. The ECM then increases fuel pressure to match the RPM.

Since you changed the fuel pump you need to check the fuel pressure.ed

can you spray it with brake cleaner or caarb cleaner in the intake breather hose to see if it will run might not b the fuel pump.could be spark or we call fire .if you spray it and it runs ,yes its a fuel problem if not spark or compression

Trouble Code: U1000

Controller Area Network Line Malfunction

Possible Causes:


CAN connector is damaged or is disconnectedCAN communication line is open, shorted to ground or to powerOne of the modules is shorted and pulling the CAN voltage low

ok pull a plug wire off might take two people scewdriver stick in plug socket turn truck over hold scewdriver close to metal :) hold in of scewdriver) if ya got fire then you prob dont have gas if ya got the tool check fuel pressure if not here is the other way:) remove breather from engine open throttle body with your hand sqiurt a little carb cleaner in release walk around an start if it tries to crank theres your answer fuel pump or maybe fuel relay but un likley

a possibility, is the fuel pump or fuse and relay!!

check fuel pump relay and or fuel pump pressure.
If you can take some starting fluid and spray some into the breather and it starts then look at fuel pump and or fuel pressure and or relay.

fuel pump relay is failing some times they get that way and also make you replace the pump and its the relay

Did you try changing fuel pump relay?

Start by checking if it's a fuel or fire problem. Take a plug wire off and turn motor over.If there is fire, Take the hose going from the air cleaner to the throtle body off and spray a small amount of carb. cleaner in.If it's a fuel prob.,check the fuel pump relay (under the hood in a black box) (swap the relay out with another relay in the box ) If the relay is o.k., it's probly the fuel pump. If it;s a fireing prob., start with the coil and wires going to the coil.
