2003 Chevrolet Astro Logo

Anonymous Posted on Mar 06, 2015

I have a 2003 chevy astro awd that wont start. I have replaced spark plugs, wires. Coil pack, and distributer. It started right up. I drove it 300 miles, parked it, the next day it wouldnt start again. I checked the timing, the fuel pressure it was all fine. So i towed into shop. They have had it a week. The check engine light came on. It said that the cat was bad. Which i have replaced twice in the last six months including the muffler both times. Also had a random miss fire crank shaft two wires melted together and one cut fixed. Shop told me it needs a new computer. Got a used one still will not fire. I did notice that the security light came on. Would that have anything to do with it. And how do i go about fixing that.

If security light is on, turn the key on and it may take 15-20 min for it to reset. Turn key back to off and then try to restart. Security light should be off and it it should start. If you for instance use a key, like a spare that you have not been using, security system may recognize a difference (because of wear, etc) and think someone is trying to steal it. Good chance that will work. Secuirty system sounds to be the problem.

    If you indeed have spark and fuel the NEXT BEST GUESS is the crank position sensor. It's not firing at the correct time to make it run.

SOURCE: 2004freestar will not start

Go to town hall on edmunds.com and look up 2004 Ford Freestar engine problems and be amazed. After the anger subsides, file a report with the NHTSA to become part of the investigation.

My cabrio wont start it will crank but not fire

When you squirt water on plug wires and the car stalls, that means that your plug wires are bad. PLUG WIRES (not rotor, cap, or any sensor).
Replace your spark plug wires with new, and you should be fine.

No spark at plug wires, but have spark at coil on 2002 chevy astro van

Is it a strong spark at the coil? If it is to weak it won't travel through the wire.

I have a 2003 Saab 9-3 Turbo convertible, I have replaced the coil pack, the battery, starter, fuel pump, crankshaft position sensor, spark plugs & more, the engine cranks like nobodys busines

did you check for voltage at the coil pack low tension input
this comes from the electronic ignition and the distributer dc setting on a multimeter

check inside the distributer that the little magnet is still in place on the rotor and that the sensor is outputing pulses as it turns over
{you can use a meter set to AC range for this ...}
pull a plug out and place its metal to ground check for actual sparks
if this is there then its fuel ...

Car wont start in the rain/cold weather changed everything electrcal wires /plugs /roter/ spark plugs /all sensors /still wont start cant go to work /do nothing

Check for fuel delivery problem by spraying starting fluid into the intake and observing whether it starts for a few seconds or not. If it does start, and dies, then the fuel pump may be at fault. If it doesn't start at all, check for spark with a spark tester off of one of the spark plug wires.

Not getting spark

Testing the coil packs.

1. Get an INSULATED wire and hook it to a ground on the car.
2. Get some one to help you
3. pull a spark plug wire off the coil
4. hold grounded wire close to, but not touching, the part where the spark plug wire connects
5. keep hands away from coil and have your helper turn the engine over ( start car and turn off)
6. if there was a spark between the wire and the coil pack it is good. if not, the coil pack needs replaced
7. replace the spark plug wire
8. test the rest
