I have 1984 Dodge van with 88,000 miles on it. For last few months it has been difficult to impossible to start when either the engine is hot, or the ambient outside temperature is hot. For instance, it starts fine in the cool hours of the night or early morning, but if it is midday 95-degree weather, it will not start most of the time. Likewise, if I drive it somewhere and the engine warms up, when I get ready to leave the store it will not start. Sometimes it takes
30 minutes up to 2-3 hours before it will start. I've left it to cool off then went back to start it later. I'm scared to drive it anywhere, since the probability of being stranded is high. I have had two different mechanics work on it. The first one couldn't find the problem and did a tune-up. The second one replaced an ignition switch and relay, but that didn't solve it. I intend to take it back in. Any suggestions that I should have the guy check? If they don't figure out what it is, I'll only be able to drive the van in the winter. Thanks for info.GS
