Hi Guys... Just got off the phone with my mechanic...He is at a total loss. It ran Fine for 45 minuets this Am, then died, and wont stay re-started for more then 2 min now.
He says: the "intermittent injector has NO pulse"
His name is Bill, his numner is 951 698 5432
If anyone has any thoughts, please email me so I can tell him, or call him...
Thank you for any help you can give me...Just want my lil guy back

He also cant seem to locate a "crank angle sensor"???

dr bob

Hmmm. His number starts with 951. A sign?

Does the '84 L-Jet have the infamous "green wire" guys?

Bill51sdr

Also, other manufacturers that have L-Jet FI put "Crank sensors" in the distributor, usually a Hall Sensor. Having never worked on a L-Jet 928, I do not know if this is the case with Porsche. Anyone care to chime in?

Green wire.
No crank position sensor.

I had similar problems. Replaced injector & fuel pump relays. Removed alarm module completely + jumpered the alarm at the Z plug. Cleaned grounds. These things fixed it.

Does this specific car have an alarm circuit?

Bill51sdr

Socalgirl, I suggest you have your mechanic call Jim Bailey at 928 Int'l 714/632-9288 and have Jim educate him on the infamous Green Wire. I have a feeling it is at the root of your problem

Mrmerlin

check to see if the car has an alarm, let us know please

socalgirl

It has no alarm that I am aware of...
Two days ago he replaced the fuel relay pump, after he replaced the alternator

KraigG

You're thinking of the infamous "909"

socalgirl

Thanks for the Email Bill
Jim, would it be ok if I have my mechanic call you tomorrow?...

Hey Jim, I passed your phone number along to my mechanic. His name is Bill, I believe he has a Green Wire question. I would be happy to pay you for your time, the advice and assistance would be invaluable to Mr Guesswork!
Thank you so Much Lisa
