Hi all,
I have recently bought a 280Z 1978 in London UK. It was an ex Cali car and from the license plate hadnt been driven since 2007. Ive spent the last couple months trying to get her to run right, however She went from initially running a bit rich/smokey to now not running at all.
Ive replaced the fuel pump as the old one was dying on acceleration (Installed a fuel pressure gauge). Ive replaced all normal things, spark plugs, oil, etc. The loom was very corroded so I have replaced the injector plugs with new ones, making sure to keep the right wire numbers/code from the handbook illustration.
The AFM has been siliconed shut as in it has been perhaps tinkered with before. However I have diagnostic tested it and all readings read are that of factory. All readings from the ECU are fine.
I have a vacuum leak somewhere, as is sometimes runs when all the hoses are off, if i go to reconnect say the breather hose back on to the rocker cover it just dies. Im stumped on that one.
Starting to get really frustrated and have even thought of ripping out the F.I and chucking in some old carbs off a 240 or even still, breaking the bank and going with triple webers! Obviously this is not the desired outcome I just want the bloody thing to go!
Any help would be great as like everyone here, I want to enjoy her, especially now that summer is here!
Thanks
JD
