Hi Guys:
Worked on it for several hours today, still same issues I dont have a NOID light and could not find my O-Scope leads (it has not been plugged in in over 10 maybe 15 years so not sure it will even work anymore it was a 20 buck unit donated to the local school.)
I Pulled #1 plug confirmed TDC and Timing Mark, cleaned distributor cap pins and rotor, re-adjusted the distributor after pulling the jumper to set timing to off. Re-adjusted Timing to ~14degrees it was retarded about 5 deg. I pulled the plug to the distributor and re-inserted checking for possible corrosion no change.
Plugged jumper back in no change would not start, took a shot of ether to get it going would not start without it and still similar issues timing stayed the same throughout the RPM range & under quick throttle response I get no advance from the distributor advance. SHOULD have had an advance...
The PCM controls both the fuel pump OFF/ON relay & the Timing Advance so was next to look at. So I pulled the Plug/connector and re-inserted it to see if there were issues w the plug, did the same with the Fuel Pump Relay and PCM Power Relay, no change... SO pulled out the PCM it is in the trunk ready to head to junkyard for a replacement..
Still thinking it is SO aggravating not being able to FIX the dang thing.... Thanks for help so far.
I didnt look closely at the grounds on the truck/battery side will take a closer look there and will also put a meter on the injectors individually looking for shorts...
thanks guys
