August 1, 201212 yr Author comment_397385 Zed sorry for my lack of clarity, I disconnected the solenoid wire from the starter and then turned the key to the start (crank) position and could hear the fuel pump run.I have till the end of next week to figure it out, I spoke to John Williams and I will bring it to him if I can't solve it by Monday.I will check the constant voltage tomorrow and let you know.Thanks again for all your helpRandy Link to comment https://www.classiczcars.com/forums/topic/43951-1978-280z-fuel-pouring-from-throttle-body/?&page=3#findComment-397385 Share on other sites More sharing options...

August 4, 201212 yr comment_397666 That's the old raise the radiator cap and back another car under there and lower the cap. Just kidding! Those new injectors should really help. Put a Fram G3 fuel filter from walmart, $4 bucks, between the tank and the pump and keep all the new goodies nice and clean. Nice work, do it right the first time.

August 7, 201212 yr comment_397834 Normally I would say throwing parts at the problem is a waist of money, but most of the items you described are common replacements for a tune up and maintenance, but what do you think the main culprit was? glad to here you're up and running again. How much did the injectors set you back?

August 7, 201212 yr Author comment_397850 I got the injectors from autozonepro.com They dropped the price to 35 per injector at the pick up counter. They were new injectors (GP brand) made in Germany.If I had to guess I would say the CSV got stuck open.
