1997 1500 5.0 (M) 2wd.I've already replaced fuel pump, cap, rotor, plugs, wires, module, csfi module, fuel filter, pick up coil, coil, starter. I first tried to start her with injection cleaner, it worked. Now I cant get her to stay running. Spark is good, fuel pressure is good. Fuel pressure stays at 59 for 10 mins before it starts to drop. I have restabbed the distributor 3 times now and no results.I work at a shop and none of the techs can figure it out. Weve got atleast 75 years worth of experience between us all. I'm am broke and exhausted.I dont know what else could cause it not to start. I pulled the plugs for the 3rd time and #3 n #5 were the only ones that were dirty, bent valves? I'd appreciate any help you can give me. Thanks. :

You can compression test 3 & 5.
I would expect a ruogh run though not a no start.

I have already tested 3 n 5. 3 was round 140 n #5 was round 130. I do not know what a poppet valve is though. Thanks for a quick response.I'm lost.
And I have not pulled any codes, there is none to be pulled. I tried to switch batteries and lost all codes.
