If the car is being stored for long periods of time, are you using a fuel stabilizer in the gas tank?

Is it turning over and just not catching for a while?

If you store the car for an extended period of time, (one month plus) I highly recommend the use of a fuel stabilizer. Todays fuels are very unstable. Also, keep the fuel tank filled before placing it in storage.

Nope, but someday.
questions, please

HI there,
First off, do you have a check engine light on the vehicle??????
Second, has anyone serviced your car recently??
When the car finally starts, do you see any smoke out of the back of the car, and do you smell anything, like gas??
Please let us know, c4c5

no warning or check engine light comes on. last month i had the oil changed but no other servicing. no smoke out the back and no gasoline smell. just no start on first try.

Ok, the next move I believe would be to check the fuel pressure with a pressure gauge.
A vehicle that sits as much as this, may have a bad vane in the pump, so this should be your next course of action, because if you were NOT getting spark, you would see black smoke, or light gray smoke out of the exhaust on initial startup, due to fuel loading in the cylinders.
Best , c4c5

hey c4c5 -

you mentioned something about gas smelling smoke kicking out the pipes when the car is started; my 87 coupe does that all the time. i thought the engine was just old. is it something else that can be fixed??

lunar, it's probably the valve seals; not the guides, the seals. A lot of Chevy engines did this, my truck did it when it was brand-new in '88. My '87 Corvette does it after it's been running, then sitting awhile , then re-starting. If it sits overnight, there's usually not that much smoke.

The General changed the style of the seal sometime... (?) It's something that can be fixed without removing the heads, if you're thinking of repairing it.

Hi LUnar,
Well, Ken is right on the money here, as the exhaust valve stem seals do break away after time, and the oil that drains down the valve stem ignites, when the first few fires occur.
However, you may also have leaking fuel injectors, which are common on your model.
You can confirm this, by checking your fuel pressure drop, once the flexible lines are pinched off.
This takes the fuel pump and pulsator out of the loop, and if any leakage is present, it will be an injector.
Let us know how you make out, c4c5
