So, after a long, cold hard winter and burning up my plugs, I got some new ones. Ordered direct from indusadist. Pulled the old plugs which were all pretty blackened and rusted, but none were swollen. Installed the new ones without incident. (All Wellman 070s)
But nothing changed. I'm still only getting white smoke. Engine cranks and cranks but won't catch and fire up, even with temps in the high 70s.
Some of the connectors seem a bit loose, so I'm going to replace all of those, but I wonder if there isn't something else going on. If it were a GP issue, shouldn't it still fire up with temps close to 80 outside?
Also, the wait light comes on and stays on for way too long. Relay clicks on, stays on for a long time, then finally clicks off, but over a minute later. Never really stayed on for more than 10-15 seconds before this past winter. Also, when it does fire up periodically, sometimes the wait light comes on for a few seconds while running right after start-up.
All plugs still show proper resistance (most are right at 1.5). Relay shows 13v at top post and 25v at bottom when activated.
From my searches on here, I'm thinking possible solutions are:
-new GP connectors
-GP relay
-bypass GP control card (haven't checked if it's burnt up yet, we'll see)
-Replace lift pump (AC Delco 43254?) & Install new check valve (HPCA off IP?)
Any other thoughts? I don't quite get the "bypassing the resistors on the firewall" mod. Not sure if that would apply to my situation.
Sometimes after trying to cycle through 4 or 5 times and shutting it off to let the starter cool down, it will finally catch and then it runs like a dream (other than a serious vibration at speeds over 55mph, but that's another issue for another post...). Once it's warm and pumping fuel, it will be fine to drive around town. But if it sets for more than 4 or 5 hours, it goes back to hard starting.
Seems like the problem I'm having isn't unique, but the causes are wide and varied. Any suggestions?
