Car Forum / Oldsmobile Cars / April 200694 Regency intermittent no-start
3600 starts good cold, starts good hot, but leave it sit an hour, no start. Just cranks. Let it sit 2 hours and get cool and then it does start. Power's good, fuel economy good otherwise. 126,000 miles Was convinced it was the O2 sensor (heard that one on Car Talk) , but that didn't help. Then I tried ignition coils, coolant temp sensor, new plugs, ignition wires, fuel filter. No change. Then found that there is no spark to any plugs when it's in it's mood.. Is there another sensor I'm missing ? Ignition control module? Maybe it's got a French part that's on strike. At some point you really need to just randomly stop putting parts in this and have it properly diagnosed, do you have cranking rpms on a scanner when this happens, do you have injector pulse? > 3600 starts good cold, starts good hot, but leave it sit an hour, no > start.

This old car is an OBD-I and I couldn't bring myself to the additional investment for OBD-I capability since this is the last car I will be able to use it on. Can I check for an injector pulse with a DVM (which I have)? > At some point you really need to just randomly stop putting parts in this > and have it properly diagnosed, do you have cranking rpms on a scanner [quoted text clipped - 17 lines] > ----= East and West-Coast Server Farms - Total Privacy via Encryption > =---- A cheap noid lite set will come in handy on all injected cars. > Shep thanks -- all I have is an OBD-II scanner.
