‘85S ROW 5.4L stroker running LH2.3
Been having hot start issues lately. Car won’t start after sitting for 20-30min. Cranks, but won’t start. Has almost stranded me a few times, but it eventually starts right up if I let it sit long enough, which seems to vary.
- Swapped fuel pump relay for new, no change
- Jumped fuel pump, can hear it running, but no start
- Fuel injectors are original to car, tested and cleaned by witch-hunter about 9k miles ago. (I suspect they may be dribbly)
I’ve read a couple threads that point to the fuel pump check valve, mine is original to the car. A easy $25 possible fix, but it seems that it may be NLA. Has anyone found a work-around? Or a way to test if mine is working properly?
I found that the air hose between the fuel pump check valve and the other little metal control valve is cracked at the bend. If I recall correctly, this hose was NLA also when I last checked. I’ll try to repair with some adhesive-lined shrink tube for now. Wondering if this is leaking vacuum and my fuel is boiling.
Thanks for listening.
