1992 Chevy Silverado won't restart

Ok guys the fuel pressure is 11 pounds and the book says it should be between 9-13 pounds. Have replaced iac and tps. Any other thoughts on what problem would be?

Yes I have spark haven't been able to check to see if have fuel pulses. It has always died when i'm by myself and I just pour gas in tbi and it fires right up and it may go a few days before it does it again.
Thanks

It may not be spraying if I have to pour gas in to get it started, but I will check the next time to see.
If it's not spraying do you have any idea of something else I could check? Thank you for your help this is driving me crazy.
Thanks again

PLEASE HELP; I checked the injectors when the motor died and I am NOT getting any pulses when I try to restart. I can pour gas in the tbi and it will start.
Thank you

I just replaced the map and it didn't help.
I will test the injectors and get back to you.
Please excuse my ignorance, but how do you test ecm driver ground?
Thank you for helping, maybe we can find the problem.

Tested the injectors and am getting voltage to one wire on each side but could not get pulse on other wires.
Thanks

Thanks for answering; I went out today to crank it and it cranked up but when I put it in gear it died, so I replaced the egr solenoid valve and the ignition module and it cranked right up and drove perfectly!
Maybe the module was going bad, it was a little coroded and had been on the truck for 16 years, so maybe that did it. If that dosen't fix it I will have the computer tested. I will keep you informed and thank you very much for your help and have a Merry Christmas.
