After a 45 minute freeway trip I was looking for a parking space when the accellerator became unresponsive and the car died about 3 minutes later and would then crank but not start. 8 hrs later I successfully started the car and drove it about three blocks before it died the same way as before. I towed the car home and since then the car will start and run for about 15 seconds at a time every three or four hours before dying. I removed the fuel filter and found that I could blow through it fairly easily. Service manual suggests shorting the fuel pump circuit through the diagnostic box and then feeling for pressure in the hose above the filter. When I do this, I can hear the pump making noise in the fuel tank, but I can't feel any pressure in the line. What's going on?
please help!!! cant get camry to stay running

-------- Is this an older car where there could be rust in the tank clogging the inlet? Before you said you're not getting any fuel pressure, I would have suspected an electrical condition appearing with the engine hot. One would expect more fuel demand on the freeway than while looking for a parking space. Doesn't quite sound right. Maybe try double checking for spark before continuing to trouble shoot the fuel system. Factory manual suggests using a hot air gun on the distributor or coil to simulate engine heat while testing.
Check your fuel pressure, on a 91 it should be 33-37lb, or fuel pressure regulator or you are getting to low a voltage at idle to run the pump properly , 12v is minimum.
Check battery and cables.
Look into the ignition module.. sounds like it from this angle.
He said he removed the fuel line and cant feel any pressure so if he has the minimum 12v look there before an ignition module, Also a coils fail often not ignition modules.
