I'm having a problem with my 93' blazer. It starts normally most of the time and runs great, but sometimes (getting worse) it won't start without priming, or turning the key on and off, usually 10 times. I have hooked up my auto-xray, but I don't know what values are normal, and which ones are out of normal range. Also I noticed that my ecm is in open loop each time the truck is started. I know this is normal when cold, but is this normal in an already warmed up engine. It does switch to closed after about 30 seconds. Any help appriciated. I have to fix this myself, I havn't any money to get it fixed. I have a new baby on the way, end of august.
