well I had posted that my truck was running good..... that was only for 10 min and now it's a no start again...
1993 GMC Jimmy 4.3 CPI
ran good , but started acting like it was out of fuel again.... now no start.... checked fuel pressure and I have 60+ psi while cranking and with the key on..... maybe it's not a fuel problem....
is there a way to test the coil?.... I did the "screwdriver trick" and saw a spark, but could it be weak?
just looking for some direction to see what to check next..... don't wanna spend $200 to have it checked out.
(edit) also showing EGR and IAC trouble codes..... any help appreciated.

 

Probably would be best to keep this in the previous thread... Just so we don't duplicate the steps that were already suggested...
