I'm looking at a 1993 Corvette 6 speed. It's a two owner car, the second owner being an old friend of mine. He passed away in January of 2015, and his sister has decided to sell it. It's black on black with a leather interior, and only 17,000 miles. I can get it pretty cheap, but wondered if there were any well know trouble spots with that year. Not planning to autocross it, just a street ride.

Imagine the carnage after over 10 years. She took it to a dealer, (OMG!), who found it had no fuel pressure. They replaced the pump and strainer, drained the old fuel, and charged her a little over $1,000. I'm still tempted.

Before you go the dealer route, check your fuel pressure by tapping into the Schrader valve on the fuel rails. Turn on the ignition to energize the fuel pump, but don't start the engine. You should see a fuel pressure reading of 43.5 psi (optimal) or a reading within the range of 38-46 psi. If the fuel pressure is off, it will affect the whole system. If your reading is too low, change the in-line fuel filter (underneath the Vette on the passenger side), and then retest.

If the fuel pump needs replacement, it's an easy job on the '93 Corvette. Remove the fuel filler door, remove the rubber tray gasket, and then remove the fuel sender/fuel pump assembly. I've done my '89 several times over the years. (The last time was because 10% ethanol fuel destroyed the ground wiring connection on the fuel sender. The replacement assembly I got from ZIP Corvette for good for E85 so I won't have that problem again.)

If the fuel pressure is within limits, the next suspect would be the injectors (providing there are no vacuum leaks detected). Try Techron fuel injection cleaner first by adding it to the fuel tank to see if that helps. If not, and you haven't discovered another reason for the hard start/idle, you'll need to remove the injectors and have them cleaned/rebuilt or exchanged for new ones. I like the Fuel Injection Connection for their parts and service.

Hope this gets you going!

The current owner already took it to a dealer. I've all but talked myself out of it. Once the fuel issue is fixed, there may still be an issue with the opti. I simply don't want to buy another project.
