Question about 1995 Chevrolet Camaro

1 Answer

I have a 1989 iroc Camaro 5.7 multiport. just installed a new engine. ok car runs fine I dive it to work and that's about 25 miles. for got to say I also put a new fuel filter and fuel pump in. about 1/4 tank it starts to die out. so I limp it to get gas and fill it up no problem runs great so I am thinking fuel pump installed wrong. its done it to me a few times now but have been noticing that the gas gauge is always diffent. now it does it at 3/4 tank. but notice that when im getting gas that my tank has a lot of pressure in it and when I release it buy taking the cap off it runs fine. was wondering if its just a pressure thing?

If you replaced fuel pump, you should have checked orientation of float to make sure it doesn't hit a baffle or anything.
You can use resistors to see if fuel gage reacts properly to the resistors, 90 ohms is full
0 ohms is empty. The wire colors for sending unit are pink and black. Take connector loose, use resistor between proper terminals, key on. If the gage reacts properly, the problem is in the gas tank.
Use a gage, check proper fuel pressure, 34--47 psi.
As far as pressure in the gas tank, check evap system where applicable or vent tube.

i would check the fuel pressure and see what it reads. im not for sure what the reading would be for that year model. you can call your local service department and see what they are. check them with the key on and vehicle off, then check them with the car on. if you dont get the right readings you are supposed to then i would say the fuel pump is not doing what it is supposed to do.

Have a dealer or garage check your Oxygen (O2) sensor. As a quick fix, try disconnecting and reconnecting your car battery. Sometimes this will reset the check engine light.Good Luck!

Steam from the exhaust means, unfortunately, that coolant is entering the cylinders, and very little running like that will destroy the rings and pistons. It could be anything from an intake or head gasket leak to a cracked cylinder.
