What is in the plastic box that is mounted to the side of the fuse box under hood on left front? The box has two connectors going to it with 4 wires to one and 5 wires to the other.it is about an inch thick and maybe 4x6 inches square and just has "GUIDE" printed on it. Car starts sometimes(and runs fine) after tweaking connectors. Connectors and wires are in good shape. When it won't start still turns over and have fuel and spark. Thanks, Phil

Phil:
Is it possible for you to upload a picture of it or give me a part number. There are so many different connections that are there. Also, if you have fuel and spark, it has to run. Unless, the injectors lose power. Have you checked that?
