Likely trouble-spots for heat-related intermittents include connectors and relays located near sources of engine heat such as the exhaust manifolds, exhaust pipes, radiator or heater core. Best of all, TSBs will usually show you which components or wires to check so you dont have to search through pages of wiring diagrams in an attempt to figure out which circuits are which and what goes where. Period. To check wiring continuity, youll need an ohmmeter, DVOM or self-powered test light. Environmental factors often play havoc with electrical systems, too. I have a 98gmc Yukon suburban with breathalyzer installed but the hot wires to it were cut and hanging down under the dash.they didn't have tape or wire nuts on the ends.I shoved them up and the end of one hit something right near the diagnosis port.acloud of smoke came out from under the dash. With the power to the fridge disconnected, disconnect wires to the heater, plug the power in and repeat what sequence was making it blow the fuse. (There's an outside chance that one leg of the circuit is still off, which can cause super-weird stuff to happen.) I would like to find out why this happened. Bad contact in or at the circuit breaker itself (or the neutral at the panel) would show itself as the entire circuit going out. There are a few things that could cause your fuel pump to start working intermittently. I'd however suspect this is more likely with some mass produced items. Most often, its due to the failed circuit that prevents the ignition system from engaging. That the timer would not advance in sensor dry is probably related. .
