96 Z28 Convertible rebuilt LT1 to stock specs, and driven approx 4000 miles since rebuild, and it just quit on the street at wide open throttle. Had it shopped and was told there was fuel pressure, and he thought there was spark. He couldn't get to the job for some time, so I towed the car to its winter storage. Now that I had a warm day, I connected my fuel pressure gauge and turned the key on and saw 45 plus psi but it quickly dropped to 0. There appears to be a relay clicking sound just before the pressure drop. Shouldn't the pressure stay up with the key in the on position? The car will crank, almost start, and slowly lope a few rotations, yet, it has no affect from throttling as it lopes.
Also, I suspect the new replacement Accel opti may have dropped its rotor screws, causing this problem. Past posts read something to the effect that a rotor screw has been known to remove itself over time. Is there a way of knowing this without full removal of the opti?
There was a previous CEL code that told me that my crankshaft position sensor was out of sorts, but the car ran fine under that condition. I did change out my CPS with cheap auto store replacements, (yes, my next one will be a factory part) but the code kept returning. I am in Chicago where an emission test is required, and due in two months. CEL is not acceptable.

Sorry for the long question, but I am trying to cover all the basics.

 

check your oil for gas smell. if injector is stuck open it will drain down into the oil. have you hit it with a shot of starting fluid to see if it will help? it does sound like it could be the opti, coil or ingition module.

 

As I suspected, I pulled the Accel Distributor and found both rotor screws at the bottom of the unit. The only problem I see with reassembling this unit is that the indexing tabs that center the reluctor ring were sheared and I don't think I would get proper or exact timing if I tried to reassemble as is. I ordered a new Accel unit from Autozone with a 20% off coupon code, and expect delivery in 3 or 4 days. I will apply lock tight this time and expect this one to last. The previous unit gave me no problems, and provided expected performance until the screw incident.
Another question. Upon disassembly of the front of the motor, I discovered a copper ground strap which is attached to the bolt that holds the coil to the head. (I may have damaged it when I removed the air pump). I need to know where the other end attaches to. The strap is maybe 12 inches long so its other connection cant be to far away.

 

i would have tried to return it. faulty part failed. that brand is not the best for opti's. be sure to locktight the screws on the new one. the ground strap should go to the frame.

 

The day my MSD opti came in, I brought it to work, tore the cover off and loctited the screws in. Never had one come out personally, but I wasn't taking any chances.

That strap should go from the head, to the driver side frame, just below the ABS block.
