Engine not starting?

Sounds like the fuel pump is pumping, but not strong enough. If you borrow a gauge from AutoZone, you can check the actual fuel pressure. Your van requires somewhere around 60 psi at a minimum to start the engine. Much less than that and it will struggle to start. This is a very common issue with the S-series trucks and the Astro van.

Please run down this guide and report back.

I get that, but you probably are not getting enough pressure. If it is less than about 60 psi, then the van will not start. But it could still be enough to idle the engine after starting it with starting fluid. So again I suggest checking your fuel pressure and getting an exact reading of what it is.

Here is our how-to guide on checking fuel pressure: https://www.2carpros.com/articles/how-to-check-fuel-system-pressure-and-regulator

Check it with the key on, and engine off. You can borrow a fuel pressure tester from AutoZone for free, you just have to put a deposit on it.

The image below is a direct pull from ALLData. Let me ask you this, when you do start it with the starting fluid, does it stay idling on its own, or do you have to keep spraying starting fluid down the intake?

Okay, Is the service engine light on? If so, you will need to get the codes (can be done without a scanner). If not, then you will have to check your fuses. In particular look at the ones for INJ (injectors), ECM (computer).

Here is a how-to guide for getting those codes: https://www.2carpros.com/articles/buick-cadillac-chevy-gmc-oldsmobile-pontiac-gm-1983-1995-obd1-code-definitions-and-retrieval-method

Try that and let us know what you find.

Try having the battery load tested to check its condition-if its good connect it properly/cleaned and tight and retry.

When you turn key to On do you see all the lights that you normally see. Could be the ignition switch

If you do see the lights-have helper put key to start position while you bang on the starter-if it engages the engiine the starter is bad. If not check the purple wire at the starter solenoid for battery voltage. This is where we stop till you get back.

When it refuses to restart, have a helper crank it, while you visually check for spark at the spark plugs. If no spark, check for primary voltage at the coil. We can go from there.

Hi Maygion stark,

The two answers you are referring to are actually your own re-post. I have forwarded your question to one of our expert professionals. You will see a new response soon.
