Turns over fine but only starts when I use starting fluid then dies I thought it was the fuel pump but I put a new one in. Its getting gas all the way to a fuel pressure valve on the manifold area after that not sure what to do plus I couldn't here the pump intel I replace it.

Have you checked the actual fuel pressure yet?ALso have you checked to see if you have battery voltage to the injectors with the key in the run position?ALso the other wire to the injectors should be a pulsing ground while cranking?

Iam trying to figure out if you have the fuel injectors inside the intake manifold which would have a large connector on top of the intake manifold. Or can you see each fuel injector with each connector going to it?We have a fuel problem so checking the pressure would be a good idea and is pretty easy to do. Any codes in the computer?

I also have a 1991 infiniti g20 did not pass smog failed on the HC max 83 gp 293 meas 174 and CO failed max 559 gp 2002 meas 2142 they said timing is off it should be at 15 BTDC. And it is at 25 BTDC way to high they said that possibly could be the problem I have a timing light can u tell me how to set the timing to the correct setting or do you think it could be the problem. And wants to charge me $70 to set the timing and that would pay for the retest I thought that was a little high the smog test already cost me $51 .
