Hello All,
I have a Pontiac grand prix GTP supercharged 3800 series 2 engine
This past weekend I had changed my intake manifold gasket because I was getting coolant mixing with the oil. So after I put everything back together the car started right up, I let it run for 15 minutes. Then I shut it off and now it's been 2 days since it was last turned on. I can't get it to start. Below I will list some things I changed, replaced, checked.
Changed:
Lower Intake Manifold gasket
Supercharger gasket
throttle body gasket
fuel injector "o" rings
PCV valve
oil filter
air filter
oil
coolant
spark plug wires
Checked:
Fluid levels - fine
Fuel pressure - fine
Spark plug gap - fine
Problems:
-I had originally put new spark plugs in but the car wouldn't start so I put the old ones in and it started right up for the first time
-Fuel injectors, when I was putting the fuel rail back on with the injectors I was pushing down on it to hard and the gasket at the tip by the O rings shattered. All of them did. Some of those little pieces fell into the engine but I know I got most of them out. Some still remain in the engine. To replace those gaskets I used nylon washes. It's what the put on the new injectors made today. So I went to a hardware store and bought some. Then I machined them to the correct size. I just don't know if these washers are heat resistant.
-A vacuum line fitting ripped on me while I was taking it off. I didn't have another one to replace it with so I put it back on, put some RTV silicone on it with a pipe clamp to hold it in place.
-I am getting the check engine light, low oil light, temperature light, and the battery light. I get these lights when I turn the key to the AUX position. I don't know if those lights always come on and stay on until the car starts but I did hook a battery charger up to the battery. Since then the starter seems to work faster. Without the charger it does not try to start as fast.
-Some of the codes I am getting with a scanner is P0123 and P0118.
With all of that said, I hope I provided enough information to help someone give me advice. Like I said, it won't start anymore but it started the before and ran for 15 minutes. It sounded great.
Thanks Guys. I hope you can help.
