How does the gas get to the engine? - Cars & Trucks

ask the dealer or , go there and see part for the car there
and see what transmission it is, for 2002 the move to 2003
and see if the same (gm parts)
there are 2 engines used, why post at all lacking such a key fact?
2.2L or 3.4liter, v6 is latter.and transmission vary buy engine max power torque, and more, gear counts for economy.

Oldsmobile Alero
or ask any engine rebuilder selling engine that (ever google that)
Or ask the shop doing it.

that is the GM answer, others like engine builders/sellers
my say different even tell you what must be changed to do it

1 minutes work me. just reading at gm.com

obviously gas.

same for all engines. (no engine stated, so no exact answers)
is your gas or diesel (ill guess gas)?
gasoline and not LPG or other fuels. real gas ,nor flex fuels on E100
cranks but no starts.
blown fuses, check fuses first, ( always #1 with EFI)
bad gas.,
the first check is spark , gas dont burn lacking SPark (mr,otto cycle)
watch funny guy SCOTTY.

any engine can run on test fuel, if it has spark (Otto)
some engines will never start

1. lost compreesion 1 or more cylinders
2. melted CAT converter, blocking exhaust
3. EgR stuck open, wide, if your unstated engine has one.
4. fuel pressure zero or 10psi. dead. must be at spec.

have a look at the cable for the throttle it may not be set correctly at the throttle body easy to do its just a turning knob that ajust it

2.0L Gas Engine : 65 to 72 ft lbs 2.4L Gas Engine : 65 to 72 ft lbs
2.6L Gas Engine : 65 to 72 ft lbs 3.0L V6 Gas Engine : 76 to 83 ft lbs 2.3L Turbo Diesel Engine : 76 to 83 ft lbs 2.5L Turbo Diesel Engine : 76 to 83 ft lbs

Remove all plugd and disable coil pack (for safety) and crank engine.

The pistons on all cyc. will push all gas + coolant out of the engine.


Please use towel /newspaper to protect the engine bay and floor before cracking the engine.
The oil/gas/coolant mix will make the floor.

What engine ? could have come with three different one's ? 3.5 ,3.9, 5.3 LGZ is a RPO code - look at RPO sticker on your vehicle . Could be driver door jam ,glove box , maybe trunk .

When mixing parts from different model year vehicles in the electronic age one never knows what will happen . Try it an see what happens .

hello wyatt...... Is your jag.built with a carburetor or fuel injected?
Carb, your choke is not set to close when cold, and should be set. When set, it also sets a cam that keeps the engine running fast. Then when warm, you hit the pedal and the cam moves, and the engine speed goes to normal. Unless the choke is set, the engine cannot keep running, as it tries to run on cold gas and it can't run good on cold gas. It needs more gas, therefore, and the choke makes more gas go into the engine.

Fuel Injected, the computer should adjust the amount of gas your car is getting when cold. If not, the coolant sensor might be bad.
The coolant sensor senses the cold engine and tells the computer to add more gas. Once the engine is warm, the coolant sensor tells the computer to put the gas to normal.
So, if the sensor is not working, the engine will try to run normal, and if cold, it can't. Joe Thanks for choosing Fixya!

IF IT COME ON EVERY TIME YOU GET GAS.GAS CAP HAS BAD SEAL IT MORE LIKELY YOUR PROBLEM BUT LET AUTO ZONE SCAN IT FREE TO SEE WHAT TROUBLE CODE YOU ARE GETTING.

Most of the time Check engine light will come due to Gas and gas cap issues. If you ran out of gas and gas lost pressure it will bring the light on. Make sure to fill take with premium (91 octane) gas and make sure gas cap is closed completely. loose gas cap will cause the engine light to come on. If after doing this you still get the engine light warning, take to authorized mercedez deal for code check.
