my 1988 4 cylinder pickup wont start without priming it, could it be the cold start switch causing the problem?
I recently put a new head gasket, timing chain and cover, new plugs and wiring. Now the truck doesn't start unless you prime it first. I replaced the sending unit and another switch however I unable to obtain one switch from the parts store. I've been told its possibly a broken wire, I need advise.
Have you checked the cold start injector and switch?
yes but cant get ne from parts stores, they advised they cant even order it.
So if you have checked them, is the injector bad or the switch?
the switch shows ohms going through. could it be the injector?
Both of those are high fail units, the switch controls the ground for the injector, so you need to check for power to the cold injector, if you have power and ground the injector should trigger, if it don't then the injector is bad.
