Here's the scoop, 85 K5...Symptoms : Cranking big time, doesn't sound like it's firing... This happened me last year, and thru this site, with everybodys hekp, I traced it to the ECM... Now, here's this years problem.... Go to start it as normaal, turns over (craanking) fine, but isn't firing..... Batt volts are hovering aroun 10 V.....Hmmm, I thought, and jumped it with my wifed 96 Concorde...... The pos (*_ terminal on my battery started to smoke, but why I thought?// I got that Battery in September..... Anyway... Btt V 10V.....I bought a can of 'starting fluid', sprayed it in, and it started and runs sweet...ALL DAY....I know, that tomorrow morning it's touch snd go as to if, or if not it'll start...It can't be the ECM again???? That was my first thought...next battery, but, my point is, if it was the ECM, OR battery, why should starting fluid sprayed in the carb work????? Anybody any comments?
