Yes, I know, always remove the battery cable before working on the car, but in my haste to (once again) take the UIM off to diagnose my continuing rich running problem, I forgot to do it. When removing the alternator, I accidentally grounded one of the leads.

When I put it all back together (I think the problem with the richness was a crimped fuel return line causing a restriction and higher fuel pressure....I hope!), when I went to start the car, I had no juice. When I grounded the alternator lead, I blew the main fuse. When I replaced that, the car now cranks, the windows work, the headlights too. But there's no readout on my commander for the PFC, and the car will not start.

Tell me I haven't really screwed up the car. Have I messed up the PFC?

 

Check your relays. I had the same problem, caused by something else. But usually its the relays. Which sucks because they are kinda expensive. Good luck ...

 

Thanks. Is there a procedure for checking relays? Or, is it a remove and replace deal?

 

egi fuse check it.

 

My car died last night.. Found the egi fuse blown. Put anothr one in and tried to start it blew again..Alternator probably bad correct? Or what else??

 

120A is it?
