I recently purchased this car and pretty much everything is great on it and starts up at a cold start great, only thing is that when i go run errands, after about the third stop of turning the car on and off the engine will crank but not start then after about 30 mins it will start. I put this issue on a Facebook forum and immediately someone said the EFI relay is bad. After researching it definitely seems like that's the issue. SO, i tried bringing to a shop and they didn't know much about this car and the part online for a OEM used one is easily $150-$200... I saw another owner on here say they used a Bosch 30 amp relay, clipped some wires and connectors and it worked great here is the post - I'm all for trying this but i have no clue how to connect which wire to what etc., and my relay has 4 prongs, not 5 like this owners. Can someone explain how they've done this? I've seen other owners with the same issue do the same and say it solved the problems.
