[DMCForum] Re: very frustrated!! - starting problem please back on track

["Brian" <TK581@xxxxxxxxxxxxx>]

I would like to thank everybody who offers thier knowledge.  When it 
comes to electronics I am a beginner though so please be patient.

Okay, I got the starting fluid and tried it with the jumper in 
place.  It did indeed start... then stop.  duh - should have known.  
It seems pretty obvious that there is not enough or no power going 
to the pump.  What struck me as odd though is that my pump is hot 
where I never noticed that before.  I double checked the wires that 
plug in right under the spare tire well (you know, the ones nearly 
imposible to hook and un-hook - at least in my car)  The hot pump 
kind of scares me but I'm going to swap the old pump back becasue it 
makes sense in my own mind.  If that one doesn't get enough power 
then I can assume it is an electrical problem.  I'll probably get a 
new relay anyways just in case.

I hope I didn't blow anything up...
