This one has got me stumped. I'm ready to just trade it in and start anew. Here's the issue. Key in ignition. Try and crank but seems to only engage the starter as it spins but it will not start. Replaced Starter. Still having issue. Have had it towed to shop twice and each time it arrives at the shop and they go to start it it starts right up. Can't reproduce. Please help quickly . I can't keep renting a car every time this thing doesn't start.
