Hello All
Have a 09 Saab 9-7x 4.2i. crank good...no start....seems not getting spark....replace camshaft sensor, crankshaft senor, new throttle body, throttle peddle, new fuel pump, new MAP sensor....don't have a Tech tool to do C.A.S.E relearn....VVT solenoid has good screens....relays and fuses are good....
Any advice on what to check?

Hi and welcome.

Put the parts shotgun away until you find what really is going on. There's already lots on info on how to troubleshoot this issue. Recommend that you give these a read:

One quick thing you can try to eliminate a fuel problem is to spray some starting fluid in the throttle and see if it starts. If it does, then it's a fuel problem.

Changed your title to get better responses.

Hello
Tried the starter fluid and in fired up temporarily with the fluid...so I have spark....
Relays are good...thinking the dealer didn't completely program my pass lock when they replaced my theft module...
Are there any other methods to try other than a Tech2?

If Passlock was the issue, it wouldn't even crank or spark. Something is going on with the fuel supply or injectors.

hello
any recommendations on things and wiring to check...all fuses seem to be good....something is shutting off the fuel supply.....when I can get it to crank it dies in 1-5minutes....then no start just a dry crank.
thanks

Fixing Fuel problems starts with checking fuel pressure. You didn't state your miles, could be a bad fuel pump.
