I am about to buy a 1991 mazda rx7 and the owner of the car jsyt put in a jsep motor he said that everything is hooked up right but he has no clue what it acan be. when you start the egnition the motr cranks like it wants to start but it won't kick over. He said that when it was first put it it would start idle low and then die out now it won't start at all. If anyone has an ida about what this problem might be lease let me know thanx. :

 

get new plugs,wires
check the fuel pump

 

take out your spark plugs and squirt some ATF in each hole. put everything back then crank

 

Uhg. If you have to dribble some sort of liquid into the spark plug holes, just use regular 'motor' oil. That ATF garbage will do more harm than good.

wwilliam54 has the right idea. Check for spark though before spending any money. Otherwise, you'll be better off having a shop diagnose your car. Then again, a jspec is no longer stock, and some shops won't even touch it and/or guarantee their work on something like that.

Hmm... Is the starter cranking too slowly?
