Question about 1985 Oldsmobile Cutlass Salon
Hello i hope you can help. i have a rebuilt 307 5.0 vin Y olds cutlass salon. with a new 1406 600cfm edelbrock and new mallory distributor including plugs and wires. it seems that the timing can't be set correctly. when set with a timing light the car starts perfect when warm. however once cold it won't crank and i have to physically loosen the bolt and advance the timing. then she starts right up. once hot(20 minute ride or better) and i shut it down she won't turn over till she cools down for a few minutes. sometimes up to 15 minutes. I saw you stated in another post that you disconected the 4 wire ECM. was that permantely or just to set the timing?? I'm tired of trying to solve this issue and my mechanic doesn't seem to be able to get it right either. is it possible that the distributor is no good?? the bolt is nice and tight but i was thinking it could be the hold down bracket but that wouldn't make any sense since i can not turn the distributor by hand. this all started happening about 1 month ago when the temps dropped to 30 and under.
This may be a problem with the ignition switch. The ignition switch feeds power to many of the different systems- including the starting system and the dash.A low voltage output of the switch will not allow the starter relay to engergize, along with many other odd problems. A way to check this is that when it is acting up, turn the ignition key back and forth very quickly many several times, or tap and the head of the key with a small hammer. These things will normally cause a faulty ign switch to correct itself for the time being.

It seems that you have a loose wire, bad connector or perhaps the main computer itself that is causing a problem If the shop is not seeing any codes, or codes come and go, likely I'm right...but someone is going to have to actually do some intensive testing to find the real cause. You can likely get another computer from a local scrapyard far cheaper than what the dealer will charge you...as far as wiring, you need a good accurate schematic a good volt/ohmeter and lots of time to trace wiring. When checking connectors test the pin, then probe the wire going into the pin...often the problem is where a wire meets the backside of the pin, either corroding or breaking..This also applies to any modules such as the security system...what you see on the dash does not always tell you that connection to components is good. This is not a "fix, but rather, a direction to go in. (exactly what I"d need to do if I was there)
Right now, everything is suspect including fuel system, till you rule it out!!!

Good Evening, you might want to check those injectors, I can not remember for certain but that setup was sequential and when one or two have a problem it would take out the rest. Ohm out the injectors and see what you have there.
