It looked me that you have been running in a same circle for a week. You definitely need to find out the root cause why the circuit opening relay stops the +B supply, as I mentioned you last week.
Touching only to the relay does not give you any more progress. Bypassing +B and FP is only for the short time test and too long may harm your engine since +B supply is stopped by the relay which is controlled by the ECU. The ECU detects something serious that needs to prevent the engine to run and the relay keeps the contacts open. There are different items that the ECU judges so. For an example, the continuous opening of fuel injectors is one of them. To read the code is the fastest way to find out the root cause quickly.
Yeah, the fact that the car didn't start when he did the bypass is a red flag. He had fuel and no start. There's two coils in the circuit opening relay, one that operates only when you start the car and the other is energized by the ECU when it detects that the car is running. You need to run down the cause of the no start.
Ok so you got it all worked out then. Let us know what your mechanic says is the root cause. Spraying started fluid in the intake is a pretty common mechanic trick to see if the problem is related to any part of the fuel system. If it starts you would begin to suspect a fuel issue. If It does't start then you start looking at the car not getting spark. Just a test to isolate the issue more. If you knew all this already then I digress.
gave up trying to figure it out, got it towed to a shop.
At first he was thinking the timing belt jumped and through timing off bla bla bla….
ended up finding that the crank sensor was covered in "gunk", cleaned it up got the car running but was not running good at all, so a tune up was recommended and since the car was already there i just say F it, do it. The plugs, wires, distributors is what i was hoping it was in the first place because i could have done that in my driveway but the no power to the fuel pump and thinking it was electrical through me off, but apparently the issue with the crank sensor is what cause that problem.. fun stuff.
$900 later… she's runs like new and is up for sale :P I have two cars so ill just use the 4 cylinder gas sipper and slowly find something new i wanna modify, may go back to the SC world, found a CHEAP 95 black on black.
Glad you got it fixed and thank you for coming back and sharing what you found out. May help others later...
