95 Blazer won't startblazerbob91 07-22-2008, 02:13 AM The engine will crank but not start. I have a good blue spark and a steady 60psi fuel pressure. Is it possible to have good pressure and not get gas getting to the cylinders? Its a 4.3 4x4 auto blazerbob91 07-22-2008, 02:17 AM I have good fuel pressure, 60 psi and a nice blue spark, but the thing will not start. How can i tell if the injector is fireing. I don't get any codes. It's a 4.3 4x4 auto. MT-2500 07-22-2008, 08:51 AM Check for 12 volts to them from injector fuse on the positive side. You can use a noid injector pulse test light to check for pulse. Pull plugs and see if wet or dry on end. If dry give it a shot of carb cleaner. If it fires on carb cleaner you have a fuel delivery problem. Also make sure it has spark to all plugs. MT-2500 07-23-2008, 10:36 AM Yes check for injector pulse and 12 volts on pos. side of injector. Will it fire on a squirt of carb cleaner. If so it is a fuel delivery problem. Spark to all spark plugs? Pul, spark plug and see if they are wet or dry. If dry you are not getting fuel. MT blazerbob91 07-23-2008, 10:20 PM Thanks I'll give it a try. blazerbob91 07-28-2008, 03:40 AM I hit with some starting fluid and it fired up. I think I've been chasing an elctrical problems when I really have a fuel delivery problem. I had the spider replaced 50k ago. I don't think they put in a nut kit. I'm goin to take a look. How long should spider assembly work. vBulletin®, Copyright ©2009, Jelsoft Enterprises Ltd.
