Hi there.

I would start with re checking the plugs as they don't take much to foul up, with the plugs out re check spark, and if OK re fit plugs and re try

Re checked spark plugs and continued getting spark.
Mobile mechanic came out and diagnosed a crank angle sensor. I am a little dubious about this, as i understand that if the crank angle sensor has failed that you will not see any spark at the plugs. Is this correct?

Hi there,

That is normally the case, do you know what code he pulled? did you have a good spark? if spark is a problem often DFI modules can act up on these engines, would like the code if you can.

The mobile mechanic did not use a diagnostic computer he used a small tool between the spark plug lead and the spark plug and determined that there was no spark. Last week when we encountered the problem i bridged 2 terminals on the computer plug under the dash and got code 12 which after doing some research was found to be the "everything is ok" code.

there is a procedure for testing the ignition system, i will have to dig it up as it is not in this US data base.
