I have a 98 chevy blazer and I'm getting no start.

Asked by May 27, 2017 at 07:53 PM about the 1998 Chevrolet Blazer 4 Door LT 4WD

Question type: Maintenance & Repair

OK so awhile ago I replaced the fuel pump and it ran for a long time then I
noticed it was running "off/rich". I then replaced the fuel pressure regulator and
now I know I have fuel to the manifold and I have spark, but no start. I'm
chasing my tail trying to find out what's wrong and I'm at my wits end. Any help
would be appreciated,  oh and I've also replaced the distributor cap and button,
and the camshaft position sensor.

This still could be a fuel issue. Should hook up a fuel pressure gauge to the Schrader Valve to do a fuel pressure bleed down test. Do this by turning the key to the on position with the gauge hooked up, let it build up fuel pressure. Fuel pressure should be 56 to 63 lbs. Then turn the key off and let it sit. Watch the fuel pressure gauge, it should not drop more than 5 lbs. in 3 minutes. If it does drop, not holding fuel pressure within this range then the spider injection assembly needs to be changed out. Trying to repair the spider injection is just fruitless to do. The new assemblies have ben up-graded.
