98 blazer won't turn over

Asked by Mar 28, 2017 at 11:28 PM about the 1998 Chevrolet Blazer LS 4-Door 4WD

Question type: Maintenance & Repair

I have a 98 blazer, it was running really rough and throwing
a code,  had the code checked and it was the fuel pressure
regulator. I changed the fuel pressure regulator and now it
won't even turn over, it will turn over slightly then stop and
act like the battery is dead. Battery is good, have tried two
different ones in it, same thing. Any thoughts for some help
with this.

These vehicles are notorious for the "spider" fuel injector assembly to fail. You may have a cylinder with gasoline in it from a failed fuel injector. Remove the 6 spark plugs and try to crank it over. If gasoline squirts out of one or more of the spark plug holes that's your problem. Liquid can't be compressed so the engine won't crank over. Replace the entire assembly, not just the bad injector(s). Be sure you get the newer design as well. Specify that when you order the new assembly. HTH. -Jim

Totally agree with Js08016 on this...repairs to this spider assembly if they even work, never last. You end up with the same problem within 6 months. The new spider assemblies have ben redesigned.
