[QUOTE=dinasrt;773668]Based on post #13, I'm thinking O.P. may have a fuel delivery problem at startup, and THOUGHT he had a low voltage issue. Blueeyes - You need to do the tests that Padgett suggested, to rule out the battery, and/or find the drain. Buy an inexpensive digital voltage meter and just do it; or have someone else do it for you. I'm thinking now that it is merely a bad check valve and it's taking longer to start up than usual??[/QUOTE
]I changed the battery used a new 80 700 ha acc, constant voltage with voltmeter 12.8 for two days and no voltage is dropped after two days that the car has been stationary at startup I still had the problem injection, what do you mean for check valve? where it is placed in the SRT6? and how do I check if it is working properly?
