1993 cavalier won't start

[mchristine87]

I had an oil change done last weekend, and since then its been running hot. I replaced the thermostat, was never low on coolant or oil, no leaks at all. I was driving down the highway, and i felt like i was losing power, and the engine started to kick a little bit, and when i pressed the accelerator again, it kicked harder then shut off. Since then I've changed the ect sensor, checked the air filter, tested the spark plugs, the fuel pump...all of that is working. My car will turn over, but it won't start. Help?

You need to replace your fuel pressure regulator it should be near your top rails near the injectors

have you checked the computer for codes?
have you done a fuel pressure test?
have you tested for spark at the plugs?
have you done a compression test?
does the oil still look clean on the dipstick?
do you have any light brown creamy looking substance in the oil filler cap?
