Hard start in warm weather, accumulator replaced

[hog240z_911]

Hello Everyone,

Im new to the forum. Ive always been into old Datsun Z cars but a buddy of mine needed cash and sold his 911 to me. Its a 1978 911 SC and I love it but one of the issues it has is a hard time starting in warm weather. I swapped the the accumulator from Pelican Parts and I still have the issue. What should I look for next?

thanks, Hog240z_911

That's a tough call with those facts...

Does it eventually start?, spark, fuel, electrics is what you need to troubleshoot. Does it always start in the cold? Do you know for sure the starter is good, or the ground strap to the car is not oxidized? Could be so many things WUR, AAR, battery, etc.

Need more info.

Got it fixed. Took it to John Walker Porsche here in Seattle and it was the check valve. The 78 fuel pump has a internal check valve in the pump but John put a external one on for 30 bucks and I was good to go. No more cranking like a idiot on warm days.
