Got the car used, with 'check eng. light ' on, was told it was just a loose wire wrong, ran fine for a while, then quit on road, would not restart, Seemed to be heat related , cooled down restarted. this happened twice. took to a garage was told that the wiring was so messed up they said it would be to much $$$$ for them to try to fix.. in short i replaced Water temp sensor, replaced Cam shaft sensor. starts fine cold runs fine at temp. turn it off and will not restart, get code saying the Crankshaft sensor is wrong shuts car down. every thing is related to system "A" can't find any help on line with where it is, what does it do, all i get is later models with a V-6, mine is a 4 ???.
