Chevy Astro CPI Fuel Injector Install Part 1

The leaking fuel pressure regulator on my Chevy Astro needed to be replaced. My van has 175k miles on the odometer and I thought it would be best to replace the injector and regulator as a unit. The regulator kit alone cost is around $100.00, and the unit with the injector and regulator comes in at around $140.00. The fuel line kit (aka nut kit) should cost around another $50.00. 90% of the work is done form the inside of the van. Sorry for the bad lighting.

Can you tell me how much different this job would be on a 99 Astro? I believe I have a CSFI engine?

I have a 1997 gmc safari. I change the fuel pump, fuel filter and still no fuel reaches the engine. It is possible that all the injectors are clogged. thanks

@sebaelcordobe83

Check your fuel pump relay, and injector harness. If your van just called it quits with little or no notice, you may have a electrical issue.

I don't think that all you your injectors would clogged at once, but one at a time over a period of time could and does happen. More than two clogged injectors at a time would make the van very hard to drive if you could get it running.

The first symptom was the smell of raw fuel out of the tail pipe after the van rested for a while. (like six or more hours) The next indication was the engine loading up or chugging under acceleration after setting overnight.

Where did you get your parts? Around me the regulator is $50 and the spider (injector) is about $280.

If you'd stripped that torx bolt, you'd have had to taken off the whole lower intake.
