I used to have a high pitched squeal that came from a vacuum leak. This squeal would come on and off intermittently. One day the squealing stopped. Did a component fail that was driven by vacuum? Anyways, the truck may have started stalling around this point. At first it was once a month or so. But it would fire up again right away. As time progressed, it became more and more frequent. No rhyme or reason to when it would stall. Sometimes cold or hot. Sometimes it would fire up right away, sometimes it would have to sit over night. sometimes I would be going down the road it would stall, sputter, backfire and then fire up again. Here are the parts I have replaced so far: ignition coil, ignition control module and the TFI or DI distributor stator (PIP sensor). The last time it stalled, my headlight fuseable link was broken. Would this mean that the somewhere the ignition wire shorted out on the headlight circuit? This would mean that the wires would have to be next to each other somewhere. I thought a likely spot to check for shorts would be around the radiator. What color is the ignition wire that runs infront of the radiator from the battery area to the radiator reservoir area? Maybe replace that? I'm sure open to suggestions. Thanks so much!
