Haven't been able to start my 1997 Astro for about 1 month. Fuel pressure 60-64 holds for a l ong time. Spark at spark plugs. tested with spark tester. Spark shows 20kv. Not over though. No codes. Crank sensor must be ok if I get spark. Right? I discovered today the crank fuse, by the brake pedal has no power. It won't start wiht starting fluid. I test injectors with noid lights at the connector into the plum. All light up when cranking.
JA: Is the power loss consistent, or does it fluctuate?
Customer: It seems consistant. Just at the fuse and the illumination fuse above it. Tested with the key on.
JA: Are you fixing your Astro yourself? What have you tried so far?

Hello,

What was the average compression numbers of the other cylinders?

Below is the correct way to test for compression on these vehicles. Thought I would send it just in case.

Conduct the following steps in order to check cylinder compression:

    1. Engine should be at room temperature.
    2. Disconnect the BAT terminal and the terminal connector from the distributor.
    3. Remove the spark plugs.
    4. Block the throttle body plate wide open.
    5. Battery should be at or near full charge.
  1. For each cylinder, crank engine through four compression strokes.
  2. The lowest reading cylinder should not be less than 70% of the highest.
  3. No cylinder reading should be less that 689 kPa (100 psi) .

Do you smell gas when trying to start the vehicle, coming from the engine compartment?

Ask Your Own Chevy Question
Customer reply replied 1 year ago
Cranks but no start. I hve spark, gas, air. It should go. It was running fine, according to my daughter prior to parking it. The next day it wouldn't start.
I have only checked compression in the number 4 cyl. Plugs smelt like gas when I pulled them. Cylinders 4&6. The engine sputters a little and then backfires a little when I try to start. I am not sure if this has chevy PassLock, but tried to reset it anyway. No Luck. Is there a way to test for a security lock out issure or how do I know if I have PassLock? Does Passlock throw off the timing so it can't run?

I don't think you have addressed my questions. I didn't ask how to check compression and don't think the top 2 reasons for an Astro van not starting will help me. I have already check the top reasons as you can see from my previous posts. Spark and fuel I have. You are asking for a rating when you haven't really commented on my issue.
