Crank sensor?

[Dave Stark]

Okay, I've done some more troubleshooting on this with no results as of yet...

 

1.) Replaced fuel filter. Also i cut it open, it was surprisingly clean inside.

2.) Tested fuel system pressure. Falls into spec with the ever trustworthy Chilton manual.

3.) Replaced manifold air temp sensor.

4.) Cleaned as many terminals as i could find.

 

At this point I'm kind of at a loss. What sensors affect starting on the OBD1 models? :nuts:

Got his XJ into the shop today. Replaced the crank sensor, dropped the crank time by over half.

 

:dunno:

When i cleaned all my terminals I looked at my battery, aside from being 3 years old it is only 430 cold cranking amps. I was wondering if that could have something to do with it...
