My boss had me take the car out to do another job I had parts for. Anyway, I found that if I cycled the key about 3 times without trying to start it, priming the fuel pump it would fire right up, and I noticed if I tried to restart it as soon as I shut it off it would fire right back up, but if I waited 30 seconds or more, just cranking like crazy. I monitored everything I could on the scan tool while it was running, injectors seem to be working fine electronically, o2 sensors working, short term fuel trim around 0, long term bounces between -4 and -7, temp seems to match up, timing about 6degrees, cam and crank sensor reading about the same. No codes other than the no serial communication, a couple history codes for the shifter and cluster. Fuel pump turns on when key turned on, but I'm wondering if its bleeding down on pressure.

oh and I did notice that when cranking the security light stays on about 10 seconds then goes out, but isn't on any other time and definitely no security codes.

EDIT: ok I'm really confused, I tried another fuel pressure gauge, same thing when about the 3rd time I cycled the key it shot up to 58psi and the car fired right up and didn't drop below 55 while cranking, spec is 50-60psi according to alldata. but I found that if I shut it off, gauge would not drop but it wouldn't restart until about 5 key cycles then the gauge would drop to 30 and come back to 58 and start right up. Tried my gauge again which is snapon, other one is napa, just to see if any difference, about 1 psi but it acted the same. I think there is a check valve in these gauges so the pressure didn't bleed off. even after I unhooked both gauges they stayed at 55psi, had to hook up the hose that had that fuel release button for the gauges to drop.
