89 corvette wont start

[shearphysics]

ok i have a 89 corvette it doent want to start all the time. some times it starts but most of the time it doesnt want to start if i give it a small shot of starting fluid it starts but then dies again. ive tried turning it over and i dont smell gas at the exaust,if i go underneath the car you can hear the fuel pump.so i was wondering if anyone had a idea where to start.thanks

what would cause it to flood the motor with fuel, would the fuel pressure regulator being bad cause it to flood the motor or cause it to run lean

[Schrade]

A vacuum leak could cause it to flood. Where are you puttin' in the startin' fluid - right at the throttle body? Or further down - ahead of the mass air sensor?

A bad regulator could cause many problems. Pluggin' in a PSI testor to the schraeder valve is pretty easy on a TPI.

ive replaced the mas sensor and it still does the same thing,checked fuel pressure at the regulator and its at 40 psi

I doubt it's the fuel regulator.

It normally reads pressure, and once proper pressure is attained, it opens a valve that allows excess pressure (fuel) to return to the tank.

If it goes bad, I don't know what safety is built-in, to allow pressure from building up to much.

I don't think that if it IS bad, it would cut off completely the fuel flow.

How many miles? Any DTC codes? Do you know how to 'jump' the link for DTC, with a paper clip'?

Did it start all of a sudden, or has it slowly gotten worse?
