SOURCE: will not start.

The "spider" up under the plastic intake plenm, the poppets athe end of each of the plastic tubes that supply the fuel to the cylinders get carbon on them and cant spray fuel. to buy a new one at GM its $550.00 Gm is the oly place you should look for one no matter the price aftermarket "copies" are not the same and while you are in there change the fuel prssure regulator at the sam time they are bot a big problem with the vortec
Change the fuel filte also and then EVERY EVERY 15,000 mles and don't worry about the engine oil change that once every 4 or 5 years that is not nearly as important as the fuel filter nothing will happen just remember the fuel filter and forget oil changes don't worry about all that 3000 mile stuff.

Replace the coolant sensor on the front of the intake manifold.The coolant sensors on this engine does go bad and wont set a check engine light. The sensor will read about -32 to 0 degrees when they do go bad. The computer thinks it is that cold and sends tons of fuel to the engine. If you try to start the engine with the throttle depressed to the floor it puts the fuel system in clear flood mode and wont fire the injectors. Engine will start then and run very rich. The coolant sensor has two wires on it and sometimes you need to replace the wiring pigtail going to it as the sensor can seep coolant into the connector and corrode the terminals. All the parts are available at pepboys and autozone or napa. Good luck

The engine will match up but the sensor plugs may not so you may have to swap the sensors between the engines.

You may potentially have an serious electrical drain in your car circuits. The drain is slow and continuous, draining your battery charge even if you do a start. Check the cabling and look for load on your battery with a Volt meter to check for any charge drainage. Check this as a precaution before replacing any more parts.

What would case my 99 gmc jimmy to bog down and run rough when giving it gas


If you have replaced the fuel filter this year, the next thing to check is fuel pressure with a gauge. GM vortec engines require 60psi or more to run.
If the check engine light is on you should also have the computer scanned for trouble codes.

It can take 70psi to start a vortec engine cold. It should start on starting fluid tho.
You might want to look at a couple of spark plugs to see if they are in good enough condition to run. The spark could be weak under compression if the plugs are worn.
