Here is my last post

Ok my 99 1500 5.9l truck, Dose not like to start, I have to push down the gas pedal and hold it and crank the truck for a few seconds for her to fire. Then the hole Truck shakes. But when I let go of the Gas and it will die. I have to keep on the gas and get the truck moving for the truck to stay running, And other time it will start like normal. with no problems.

Could this be a grounding problem or something else.

my family calls this a money pit, But I will never give
up on this truck!!!


Thanks everyone have a great day.

I was told to replace
IAC sensor

DiD that no change. Now that its cold it wont stay started.
Any New Ideas people?

 

Did you have the battery disconnected when you replaced it?

 

ASD Relay?

 

If it were the ASD relay, it wouldn't start at all.... and gas pedal position would make zero difference. I would look at the throttle position sensor, and/or the engine coolant temp sensor. TPS you can test with a multi-meter, ECT you need a scanner to see what it thinks when the engine is cold. Might check the connector in any event, should be right near the thermostat housing.... make sure it is plugged in tight.

 

I think that's my problem on mine only its good if its cold and hates being warm

 

^Your issue sounds like the pre-cat 02 sensor going out on you.

 

When I replace the IAC sensor the battery was still connected.

 

TBS Sensor have been replace.

 

is there a by pass for the 02 sensor. as its really cold. I dont want to lay in snow. LOL

 

Nope.
