Exclamation Delayed start problem

I purchased a 2002 Maxima GLE that had heavy front-end damage. I was able to start the car prior to repairs, but it would take from 10 to 90 seconds of cranking to start. Once running it idles good and engine is strong. I had to replace the engine compartment wiring harness during the repairs, but the problem is still there. I replaced the ECM with a used one and had it reprogrammed and replaced the crank sensor and the two cam sensors trying to resolve the problem, those didn't fix it. I pulled the fitting off the end of the fuel rail and tested the fuel pressure it is right at 40psi. Sometimes it starts in 10seconds and sometimes it will just crank for minutes without starting now. There is an engine light on for the front O2 sensor and for a valve in the emissions cannister.
Does anyone have an idea were to check next? Thanks
