Well we put in the oil and Temp gauges from Auto meter and now It won't start? This is a 90 Bronco with 302. We just ditched the Stock Temp sensor but I am not sure if it is important to have it or not. Any ill affects leaving it unhooked in favour of the mechanical one? We have everything back together correctly so I don't understand what the probelm is. The temp sensor is the one at the front of the engine on the lower intake right above the T-stat housing correct? Any ideas? It started the first time we tried it but it kept stalling like the MAP or PCV was unplugged shich they aren't. Completely confused!
