Recently on two occasions the car started fine and I was driving down a garage ramp when the car died. Pulled into a open space, car turned over strong, but wouldn't kick in. Next day car turned over fine and kicked in on 10 try's. Several days later it did the same thing going down a small hill. Pulled over parked. Had car towed to garage, next day car started right up and did so on 10 trys. HELP

Hey Roach!

Sounds like the good old fuel pump relay problem, typical for these cars. Open the hood and remove the fusebox cover (4 torx screws) to gain access to the relays located there. One of them is probably a green one (I think it's labeled 103). If so you have the old type of relay and should replace it with the new and improved one, which is red (I think the part # is 9434225, but just make sure that you get a RED relay). A used one is cheap and should do just fine.

Here's a link to a topic about this at another site:

Like tonygrantham said; the problem is with spark, fuel delivery or compression. Checking a plug for spark is easy: Just unscrew it and hold it to ground with a pair of insulated pliers or something similar while the problem is present. Have someone crank the engine while you look for spark. If the engine starts while lacking one plug it will sound horrible, but will not be harmed as long as you don¨'t run it for long and don't rev it.

If you've got both spark and fuel you might want to check compression and timing even though they are, in my opinion, unlikely culprits.

Good luck, mate!

Id start with fuel, make sure it's gettin fuel. then check your fire, spark plugs dist, ect. 75% of the time that's where you will find the problem with those troubles
