Question about 2003 Chevrolet Astro

Astro van with random starting issue

My van has started randomly not starting every week or so. It turns over but doesn't start. I've taken it to a mechanic who has replaced a number of parts but not yet fixed the problem. The van computer shows a security error each time.

So far I've had new spark plugs, replaced the security module in the steering column (took a while for the computer to reset after this was replaced), new mass air flow sensor, and computer.

Any suggestions for why this is happening?
Thanks

    Had a somewhat similar problem on a 2000 Astro. Actually died once while driving, otherwise would randomly decide not to start. It sat at a garage for 3 weeks until they could get it to fail long enough to diagnose.

    Was a defective coil.

This van or tipe of vehicles have a very coming problem with the injector assembly fault, if you ever get it to star make sure to see if you see any black smog coming from the exaust or if you notice like spending too much gas then that will be the proble and this part is not too chep to replace

You never take your vehicle to places like midas , pep boy's , firestone etc.. Find yourself a local independent repair shop . Po300 is a random misfire , not cylinder specific ! Causes ,lean air fuel mixture , vacuum leaks , low fuel pressure , clogged fuel filter , a O2 sensor problem . You need to find someone like this guy !

1999 Chevy astro van won't start


Had the same issue with our 1999 chevy astro van, would crank but would not start. It had been raining and windshield had a leak, after 2 days of no rain it started. Pulled codes and was the Security system in the ignition switch. Hope this helps.

2000 Astro Random Misfire


This sounds like a classic GM plugged catalytic converter symptom. If you like you could remove the oxygen sensor in front of the cat and try driving it. With the sensor removed, the exhaust can escape a little more easily and will drive better if the cat is the problem. If you have the right fitting and a gauge, you could actually measure the back pressure at the oxygen sensor hole. It should not be any higher than about 2 psi at 3000 rpm. I have seen this problem several times now on these vans and I'm almost certain this is your problem.
Hope this helps,
Dave
