It takes several minutes to get my 996 to start, never used to be like this. Just had the eprom, ecu, and some fuel hoses in the tank replaced. Started just fine after getting it back for a few times and now it will catch for a sec but not fire up. I have to mess with the throttle to get it to start. I can hear the pump kick on with the key. It will restart fine after I have it running and it runs just fine. However after a few hours of sitting it is the same thing again. Need help!
