Hello scholars and masochists.

I’m requesting help on solving the issue of excessive cranking on start-up. Not once since I bought the car has it ever fired right up like others described for their cars. I had hoped that this issue was related to the other issues I’ve solved with the help of my friends here, but no luck. The behavior remains unchanged.

To start this off, I rigged a little hidden fuel pressure gauge to the car so that you all can see for yourself. For the context of this attempt, the engine is cold at around 60F, I did not touch the throttle and the ignition was in the on position prior to cranking.

some OT subject matter for light relief.
and for @Emerygt350 amusement.

finally made it to the tub stage on the falcon ute yesterday.
all that is left to do.
getting ext/int trim back in and fitted was a delicate task given the beautifully brittle plastic (probably since new being state of the art 1980s/90s aus heavy molecules).
but i broke nothing and its done.

had a friend who is a cultural objects conservator doing the interior clean.
all she uses is water, water, water, scrub scrub scrub (toothbrushes etc) and occasionally a very mild detergent. and time. boy is she patient. three quarters of an hour on the steering wheel. but i couldn't believe the end result. its a 300K car and the wheel came back like showroom. looks it and feels it. like putting your hands on pure vinyl again.

conservator in question has an interest in cars. her father ran one of the biggest GM dealerships in NSW and they won bathurst 500 back in 1968. but she bribed me. i had to take her for a run in the 914 yesterday for about 2 hours. which i duly did.

the car is a bit like a northern USA car. heaps of rust but perfect interior. a rare thing in aus. usually its the other way around. i dealt with the rust thanks to dickhead dan the dicktator and learned new skills, though not sure i want to deploy them again.

you will be pleased to know @Van B the local news last night was dominated by disclosure that the dicktator is vid + and has to go into isolation for 14 days.
along with his family. feel real sorry for him.

have managed to plough through 2 cars in about 2.5 years.
i'm a mere month away from getting the 914 back in and up on a hoist instead of jackstands to to the fuel pump/fuel line mods and a few other tuning touches again.

914 nearly done and ute awaiting either burial at sea or major surgery.
