Im going crazy here. If you have read my last post, car has sat for 7/8 years. New F/P good pressure good spark, I could used to make the car start by pouring gas in the TPI T/B. It wont start like that anymore. Codes just keep reading 12. Whats next??

Re: Fire, spark, fuel pressure good but no start.???

If you have fuel pressure and good spark, you are probably not firing the injectors. First to check is you have 12 volts at the injectors with the key "on" (run or crank). Then check to see if your injectors are being pulsed (use a noid light). If you find no injector pulse, search the DFI and ECM section for threads concerning "no injector pulse". It would be a good idea to replace those old injectors because sitting for 7/8 years isn't good. HTH!

Yeah, that will work fine. I have not dealt with them for injectors, but SouthBay has a great reputation and many members swear by them! HTH!
