The engine will start then stop in a few seconds. Then will not start for hours the start again and stop. I can get it to run by spraying starter fluid in the intake and it runs, so electrical is good. Timing light works on all plugs. Fuel pressure at the cold start injector, good. Cold start injector operates with 24vdc, good. I get no voltage at the connector of the cold start injector. What tells the injector to open? What is the next step to locate the problem? I am sure it is fuel because of the starter fluid test.

Re: 94 Celica GT, Fuel Problem?
This is most likely going to be a control module (ECM), a relay wouldn't have this effect. Check to see if this model has a control module for the injection system, if not the problem may lie in the main ECM. If the car has these features, check the fuel kill switch (in case of crash switch), if this switch is malfunctioning it could cause the fuel pump to turn off after the initial start, and the security system, some have a fuel kill along with an electrical kill.

Good fuel pressure, starts, runs for about 7 seconds, dies after a sudden drop in fuel pressure. ...starts 15 minutes later, runs fine then stumbles and dies again 3 answers ... I drove carhome shut off and next morning would not start, but will turn ...
Did it have this problem before you changed the fuel pump an filter ? When it dies an won't restart for hours ,is there spark at the coils ? What engine does yours have V-6 . Check for spark the way this guy does in this video. GM Ignition System diagnosis 1988 Olds Cutlass Same ignition system >
You can try this. Turn on the key and listen for the fuel pump to prime. It will sound like a gentle hum. when it stops, turn the key off. wait a few seconds and do it again. Do this three or four times, but don't try to start it. after the third or fourth time you turn it off, try to start it. It may not be priming the fuel injectors fast enough.
I had a problem like this on my 95 gt 2,2 and it was the distributor cap and rotor. I changed fuel filter, fuel lines, etc. thinking it was fuel related, nope, cap and rotor and 10 minutes of labor and shes perfect.
I had a broken wire that runs the power from the battery to the fuse box under the hood in my 94 Celica. It had symptoms of a bad battery or alternator. I spliced the wire and haven't had any issue since then.
It sounds to me as though you have a case of excessive fuel pressure, which could be due to a faulty fuel pressure regulator or a blocked fuel return line.
I don't know whether or not there is a Schraeder valve on the fuel rail of your car (it looks like a tyre valve) but if there is then it may be worth connecting a fuel pressure gauge to it and observing the fuel pressure build up.
You could also disconnect the fuel return line from the fuel rail, push another length of rubber pipe onto the rail, hold the end in a suitable glass container, and then have someone start the engine whilst you gauge the fuel flow from the pipe. It should be a good steady flow, and, if the engine doesn't cut out with the return line disconnected then you know there is a blockage in the return line and you can make arrangements to blow it through.
